Dr. Larry Sutter Retires from Michigan Tech with a New Focus: Carbon Neutral Concrete by 2035

Lawrence L. Sutter P.E., Assistant Dean of Research and External Relations, College of Engineering, Michigan Tech
Now that he has retired, Dr. Larry Sutter plans to do a lot more consulting, with a strong focus on the development of sustainable concrete.

After 43 years of distinguished service to Michigan Tech as a staff member, former student, professor, and leader, Dr. Larry Sutter, associate dean of research and external relations in the College of Engineering, and professor of materials science and engineering, officially retired from the University as of June 30.

Sutter first came to Michigan Tech in 1979 to work in the former Department of Metallurgical Engineering, operating and maintaining their powerful electron microscopes. He had previously earned an associates degree in electronics at DeVry University in Ohio and had worked for an instrument vendor for three years. Taking advantage of Michigan Tech’s tuition benefit, while working full time, Sutter took a few undergraduate courses, and then a few more–eventually earning a BS in Metallurgical Engineering. He didn’t stop there. Sutter went on to earn an MS in Environmental Engineering, and finally a PhD in Civil Engineering—all at Michigan Tech.

While pursuing his doctoral degree, Sutter joined the faculty in Michigan Tech’s former School of Technology, teaching courses in civil engineering technology and construction management for nearly a decade, becoming a tenured professor. 

In 2007 Sutter became director of the Michigan Tech Transportation Institute (MTTI), which served as a link between Michigan Tech researchers and the Michigan Department of Transportation (MDOT) and other state DOTS, as well as the Federal Highways Association. Under Sutter’s direction MTTI expanded, growing to 25 employees, focused on transportation research, education and training, outreach, product development and technology transfer, with over $3 million in research expenditures.

He also served as director of the US Department of Transportation-sponsored UTC-MiSTI (University Transportation Center for Materials in Sustainable Transportation Infrastructure). Sutter became actively involved with research through the National Cooperative Highway Research Program, sharing his extensive knowledge of concrete making materials. He also contributed through his strong expertise in material characterization measures, which enabled him to accurately assess concrete durability and the deterioration of concrete pavements.

Sutter joined Michigan Tech’s Department of Materials Science and Engineering in 2013 as a full professor. He advised graduate students and taught courses in scanning electron microscopy, and continued research on  concrete-making materials and concrete durability.

Over the years Sutter’s research focus honed in on various recycled and secondary materials for sustainable concrete, including fly ash and blast furnace slag. He is recognized nationally as a leader in development of standard tests and specifications for using these materials in concrete. 

“My professional goal now is to be a contributor to making the cement and concrete industry carbon neutral by 2035. It is a BHAG (Big Hairy Audacious Goal) but I feel strongly it can be done.”

Dr. Larry Sutter

In recent years Sutter earned several major awards. He was named a Fellow of ASTM International, formerly known as American Society for Testing and Materials. ASTM is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services.

In naming him a Fellow, ASTM recognized Sutter as “a valuable resource and advocate for the responsible use of sustainable materials in concrete mixtures, and a forward-thinking leader in integrating new and developing technologies into new and existing standards.”

Sutter’s dedication is underscored with a summary of his involvement: he is active on ASTM Committee C01 Cement, as well as C09 Concrete. He serves as vice-chair of committee C09, the second largest committee within ASTM, and serves as chair of subcommittee C09.24 Supplementary Cementitious Materials. Sutter is also chair of subcommittee C01.14 Non-hydraulic Cements, and serves on the executive committees of both C01 and C09.

“There are numerous professional activities I am involved in, to get the cement and concrete industry to carbon neutral,” says Sutter.

Sutter was also named Fellow of the American Concrete Institute, or ACI, in 2019. He currently serves as chair of ACI Committee 321 Durability Code, Vice-Chair of Committee 232 on Fly Ash and Bottom Ash Use in Concrete, and secretary of Committee 201 on Durability. He serves on the ACI Board of Direction. And now, he serves as chair of the board of the newly formed ACI Center of Excellence for Carbon Neutral Concrete (NEU).

Sutter earned the Jean-Claude Roumain Innovation in Concrete Award from ACI’s Strategic Development Council, which recognized his strong leadership in concrete materials education and research. The award committee cited Sutter’s work, which has “resulted in the advancement of knowledge of deicer-induced damage to concrete, utilization of fly ash and alternative cements, and characterization of a concrete air-void system to overall improve the sustainability and durability of concrete.” Sutter also received the Delmar L. Bloem Distinguished Service Award from ACI in 2018. 

In 2022 Sutter received the Champion Award from the American Coal Ash Association, the 8th recipient of the award over the past 10 years.

Sutter made his mark outside the world of concrete and Michigan Tech, too. After enjoying hockey as a spectator all of his life, at the age of 37, he got the opportunity to get on the ice and enjoy the game as a participant. This happened because he casually commented to his graduate school office mate, John Sandell, now a faculty member in the Department of Chemical Engineering, that he would love to play hockey—but only if he could play goalie. 

“John assured me that if I wanted to play goalie I could play 7 days a week—because no one else wanted to do it!”

Sutter has played hockey ever since, and even founded the Tuesday Night Hockey League, which involves the game (of course) but also a veritable locker room feast that Sutter prepares himself each week for his teammates.

Sutter’s love of hockey is contagious off campus, too. For each of his many ACI meetings, held in different cities across the country, where possible, Sutter manages to organize an ACI hockey game, which involves finding a rink nearby, recruiting 20 of his ACI colleagues, and playing, too. The game is followed by a reception and the event is always done as a fundraiser for the ACI Richard Stehly Scholarship with each game raising well over a thousand dollars to support the scholarship fund.

Tuesday Night Hockey League at Michigan Tech: first the game, then Larry’s homemade feast! (Larry is first on the lower left).

Sutter is a member of the National Academies Transportation Research Board, and the National Concrete Consortium. Both are leading venues for the dissemination of concrete research. He’s also a volunteer at Little Brothers Friends of the Elderly, something he has done for the past 42 years. 

So what are Sutter’s next steps after retirement?  “My plan is to do a lot more consulting now, with a strong focus on the development of sustainable concrete,” he says. “It’s time to give back.”

Making concrete stepping stones with fourth grade students (as a Mother’s Day gift) became an annual outreach event for Larry. “That was always a highlight of the year.”

Dr. Sutter generously answered our questions about himself and his plans for retirement.

Hometown?

I was raised in a small town Western New York called Perrysburg, about 50 miles south of Buffalo. I am #4 of six children, 3 brothers and two sisters

Why did you choose Michigan Tech?

Actually, Michigan Tech chose me. I came here in 1978 to install an x-ray fluorescence spectrometer in the Metallurgical Engineering department and while I was here I learned of a job opening in the electron microscope lab. I was looking for an opportunity to work at a university and continue my education, and I loved the small town environment of Houghton, so I applied for the job. I came to the interview in December of 1978, the record snow year. Professor Al Hendrickson picked me up at the airport with his VW bug and as we drove to town in that little car, with no heat, with snow banks 6 feet high on either side, I knew this was the place for me. Eventually I was hired, moved here in March of 1979, and so it began.

Part of the job you enjoyed most?

There were many highlights. Operating the electron microscopes, especially the electron microprobe, was a “gadgeteers” dream. That was and always will be the most fun and interesting job. But that wasn’t as professor or dean, that was as a research engineer.

Probably the highlight of my professor time was as director of the UTC. I worked with a very competent and resourceful staff person, Beth Hoy, and we did some very innovative things. We were able to fund a large number of students and we had numerous outreach programs to engage K12 students. Somewhere along that timeline we started making concrete stepping stones for a Mother’s Day present with 4th grade students. That was always a highlight of the year. The students would come, learn about microscopes, materials, and then get dirty making concrete.

Most rewarding aspect of your job?

Teaching in the School of Technology was rewarding as it was a two-year associates degree and I saw a lot of students that reminded me of myself at their age. The associates degree is a path into higher education that allows students to take an incremental step and prove to themselves that they can be successful. I saw so many students come in year one with the attitude that 6 months from now they will be a failure, only to find they like learning, and they can be successful in college, and by the end of year 2 they are looking at BS programs, or going to work with an associates degree and a much different career trajectory than would have been the case without the degree. I saw a lot of young people’s lives change for the better.

“If there is spare time, my first choice is to travel. I have a life goal of seeing every NHL team on their home ice at least once.” (Hopefully that includes at least a few destinations with beautiful beaches!)

Who were some of the people that influenced or helped you along the way?

In my time in the Metallurgical Engineering department as research engineer, the two influences were Professor Don Mikkola and Professor Duane Thayer. Don was the main reason I came to MTU. At one point I turned down the job offer and he called and talked me into coming; Don had a very convincing manner. Over the years he was always a supporter and a mentor, and a close personal friend. Duane Thayer was a major influence on my education and on my ultimate career path, and also a close personal friend. I became interested in the local copper history when I first came to Michigan Tech, and Duane, aka ‘Dewey’, filled in a lot of stories. I became interested in mineral processing/extractive metallurgy and that became my academic pursuit, under his tutelage. And for everyone reading this who was one of ‘Dewey’s Boys’ (and there were girls too), we all know we are in a special fraternity. Knowledge from that training is still serving me today as I work in the cement and concrete industry.

Plus, Dewey told me early on the secret of being a Yooper:  “Be the same way every day. Whatever you are, just be that way and don’t be changing on us.” 

Another major influence of mine came from another Dewey, Civil Engineering Professor George Dewey. He got me engaged in fly ash and concrete. Had he not supported me in my transition from research engineer to graduate student to faculty member, it never would have happened. He introduced me to ACI (the American Concrete Institute) and taught me much about how the construction industry works. His support early in my career was foundational. And more than anyone, he taught me how to write.

Last but not least, I worked with two professional staff, that without their skills, much of the research I led would not have had anywhere near the same level of impact. Those were Dr. Karl Peterson, who is now a professor at the University of Toronto, and Jerry Anzalone, now a successful entrepreneur and beachcomber in central California. Both were graduate students under my supervision at the time, but I received far more from them than I gave. Their laboratory skills and their work with students on the front lines made our research program successful.

Your biggest goal now?

My professional goal now is to be a contributor to making the cement and concrete industry carbon neutral by 2035. It is a BHAG (Big Hairy Audacious Goal) but I feel strongly it can be done.

What will you do in your spare time? 

I don’t see a lot of spare time coming up in the near term. There are numerous professional activities I am involved in, to get the cement and concrete industry to carbon neutral. Plus I have leadership roles in ASTM and also in ACI, most notably as Chair of the Board for the new ACI Center of Excellence for Carbon Neutral Concrete (NEU). But if there is spare time, my first choice is to travel. I also have a life goal of seeing every NHL team on their home ice at least once. So far I have 16 of the 32 teams done. I’ve been to multiple arenas for some teams, like Detroit. I try to see a couple of teams each year. 

Larry as goalie.

What advice do you give to new students? New faculty?

My advice for new students: Put your phones away, listen to your professors, and read the book. And most importantly, ask questions. It will make them a better professor and it will help you understand that not every question has an answer, and for a young engineer that’s job security.

“With intelligent questions, not nonsense, drive your professor to the point where they say ‘I don’t know.'”

Larry Sutter

My advice for new faculty: Nothing is easy but everything is possible. Don’t take “No” for an answer and never forget the importance of the professional staff at the university. They are the cog that makes the machine work. Respect them and make them part of your team.

The College of Engineering and Michigan Tech are thankful for Dr Sutter’s leadership and friendship and wish him every happiness in his retirement!

Dr. William Predebon Retires Today After 47 Years at Michigan Tech

Dr. Bill Predebon is retiring today after a stellar career as professor and chair. He will remain always a mentor, advisor, colleague, and friend.

Today at Michigan Technological University, it feels like the end of an era.

But for Dr. William W. Predebon, J.S. Endowed Department Chair and Professor, it is the beginning of something absolutely new. Dr. Predebon will retire today after 25 years as the chair of the Department of Mechanical Engineering-Engineering Mechanics, and nearly 47 years at Michigan Tech.

“As I look back on all those years as department chair, I want to acknowledge that the progress we made was on the shoulders of those that came before us and the great faculty, staff, students and alumni who have been a part of this journey with me,” he says.

“If there was a hall-of-fame for mechanical engineering department chairs, Bill would get in on the first ballot,” says Greg Odegard, the John O. Hallquist Endowed Chair in Computational Mechanics. “Bill is a tremendous mentor. He worked hard to help young faculty develop into world-class researchers and teachers. He has a very calm, non-dramatic approach to leadership. He is simply honest and straight-forward.”

Under Predebon’s respectful and brilliant watch, the ME-EM department made great strides in conducting interdisciplinary research, growing the doctoral program, expanding research funding, and updating the curriculum and laboratories. He also brought diversity to both the faculty and student body.

Predebon joined the Department of Mechanical Engineering-Engineering Mechanics at Michigan Tech in 1976. He served as the department’s director of graduate studies, and then, in 1997 he became chair of the department.

“The world is changing, and we need to respond to its challenges and opportunities.”

Dr. Bill Predebon

“I’ve been fortunate to work with Bill on many projects over the past 25 years,” says Gordon Parker, the John and Cathi Drake Endowed Chair in Mechanical Engineering. “Bill brought a level of positivity that exceeded the circumstances in every case. This, along with his unwavering focus and kindness, resulted in success.”

“Bill has had a profound and lasting impact on the careers of many students, faculty, and staff,” adds Parker. “He’s a ‘true believer’ in Michigan Tech and the people that define it.”

“Bill made great effort on the development and retention of minority and women faculty members,” says ME-EM Professor Bo Chen. “When I joined Michigan Tech, he assigned two mentors for me, including a woman mentor. Bill has always been supportive of my teaching and research. He always tried his best to accommodate my requests for teaching assistants and research space. I greatly appreciate his help on my career journey at Michigan Tech.”

“Bill is the reason I came to Michigan Tech, and the reason I am still here today,” says Brad King, Richard and Elizabeth Henes Endowed Professor of Space Systems. “When I interviewed 22 years ago, Bill convinced me of his vision to broaden MEEM into new areas, which could include aerospace, and I jumped at the chance to be a part of that change.”

“True to his word, Bill always made room for new ideas and encouraged and rewarded innovation,” adds King. “As a result, there are now hundreds of Michigan Tech alumni in leadership positions within the commercial and government space industry, one Michigan Tech satellite orbiting the Earth, and two more in development. Just last week I saw a commuter bus driving around Houghton with a big satellite graphic on the side. Because of Bill, space and satellites are now an integral part of Michigan Tech’s identity.”

“By hiring talented faculty and staff, together with our great students, our generous and supportive alumni, and with the support of the university administration, we have been able to innovate, push boundaries, be creative, take risks, and be entrepreneurs,” Predebon says.

Over the past 10 years he led the ME-EM Department to rapidly evolve its educational methods, infusing into undergraduate and graduate curriculum the knowledge and critical skills to use big data, machine learning and artificial intelligence in the solution of engineering design problems.

“Bill is the master of the long game.”

John Drake ‘64, ‘69, Michigan Tech mechanical engineering and business alumnus
Dr. Predebon’s early days at Michigan Tech

Predebon grew up in New Jersey, then earned his bachelor’s degree from the University of Notre Dame in 1965 and his master’s and doctorate from Iowa State University in 1968 and 1970, respectively. After he graduated, Predebon held summer appointments at Argonne National Laboratory, Southwest Research Institute, and Honeywell Inc./Alliant Techsystems Inc.

Predebon’s research in ceramics, computational modeling and simulation of impact phenomena, and explosive fragmentation has involved experimental, analytical, and computational elements and has been supported by the National Science Foundation, the Department of Defense, and other government agencies and industrial partners. He has over forty publications and two US patents.

A Fellow of the American Society of Mechanical Engineers (ASME), Predebon has received numerous honors, including the Outstanding Service Award for his work with the student chapter of the Society of Automotive Engineers. At Michigan Tech he earned the first annual Martin Luther King Award by Michigan Tech’s Black Student Organizations; and the Michigan Tech Distinguished Teaching Award. He received the Distinguished Faculty Award from the Michigan Association of Governing Boards of Colleges, and the Michigan Tech Honorary Alumni Award. He also gained membership in Michigan Tech’s Academy of Teaching Excellence.

In 2015 Predebon was recipient of the Michigan Tech Diversity Award, which recognizes the accomplishments of a faculty or staff member who contributes to diversity and inclusion through exemplary leadership and actions. Predebon stood out for his long-term persistence in working on issues of diversity.

“Bill has been known for his willingness to try out-of-the-box strategies for recruiting underrepresented minorities and female faculty and students,” said Carl Anderson, ME-EM professor emeritus and former associate dean of research in the College of Engineering. “He recognized the importance of a diverse workforce well before it became part of the common expectation of a department chair. He led the way.”

“My observations, from over 20 years of Dr. Bill Predebon’s leadership:

Passionate
Resourceful
Enthusiastic
Dedicated
Energetic
Balanced
Optimistic
Notable

Gerald Haycock ‘68, mechanical engineering alumnus

Predebon also led efforts to create the Michigan Tech Learning Resource Center for Self-Paced Programmed Instruction, the ME-EM Engineering Learning Center, as well as a distance learning doctorate degree in mechanical engineering, and a Design Engineer Certificate program with General Motors in 2000. More than six hundred GM employees earned the certificate.

In 2010 Predebon started a Peace Corps Master’s International program in mechanical engineering at Michigan Tech, the first and only one of its kind in the nation.

Predebon is a captain in the US Army Reserves and is a member of four honor societies: Tau Beta Pi (engineering), Phi Kappa Phi (academic excellence), Omicron Delta Kappa (leadership), and Theta Tau (engineering).

In 2019 he was inducted into the Pan American Academy of Engineering, which brings together engineers from across the continent of North America, South America and Mexico—a total of 18 countries.

At Michigan Tech he advised both the Nordic and Alpine ski teams and Delta Sigma Phi fraternity, and chaired building committees for both the Dow Environmental Sciences and Engineering Building and the Great Lakes Research Center.

“The ME-EM department and Michigan Tech are better as a result of Bill’s hard efforts. I only wish I had an opportunity to be one of his students!”

Geoff Weller ‘75, mechanical engineering alumnus

So what are Dr. Predebon’s next steps after retirement? He plans to keep working—this time in development and outreach activities for Michigan Tech, as a Professor and Chair Emeritus.

“Bill is a pioneer at Michigan Tech in advancement. He showed the university how it could be done successfully,” notes Parker.

And Dr. Predebon just might journey with his family to Italy at some point, in order to meet relatives there for the very first time.

“ I thank all of you from the bottom of my heart.

Dr. Bill Predebon

OHM and Michigan Tech Alumni team up to Lead Family Engineering Nights in Detroit Schools

Fifteen OHM staff helped present the Family Engineering Night sessions, including several Michigan Tech alumni.

From May 10-12, Michigan Technological University teamed up with OHM Advisors to provide STEM outreach at five schools in Detroit. 

The program they presented, Family Engineering, engages K-8 students and their families in engineering investigations. Family Engineering was created by Michigan Tech and partners in 2011 with a grant from the National Science Foundation. A key outcome of the program was the publication of the Family Engineering Activity & Event Planning Guide, published in 2011.

Sessions took place at the schools, followed by free pizza at Mackenzie Middle School, Clippert Multicultural Magnet Honors Academy, and Adams Middle School. The event began with short opener activities that adults and children explore together. These included: Glue is the Clue, Domino Diving Board, Who Engineered It?, Let’s Communicate, Boxing Beans, Picture This, Solid Ground, Hoop Glider, Inspired by Nature, Shifting Shapes, All The Right Tools, and Thrillseekers.

Next, families took part in three Engineering Challenges:

  1. Stop & Think – Why was this object designed? What need did it address? Can you make it better?
  1. Team Up – Discover why engineers work in teams. What helps a team work well together? How can we address challenges?
  1. Give Me Hand – How can an engineer help a person who has lost their hand, or some other part of their body?
Family Engineering Night took place recently in Detroit, with volunteer help from OHM Advisors.

Fifteen OHM staff helped present the sessions, including several Michigan Tech alumni.

Ron Cavallaro, Vice President of OHM Michigan, echoed the value of introducing kids to engineering at an early age. He earned his bachelor’s degree in civil engineering at Michigan Tech and is now a member of the Michigan Tech Department of Civil, Environmental and Geospatial Engineering’s Professional Advisory Board. “Many of the families that attended the events brought younger siblings,” said Cavallaro. It was awesome to see the middle school students, their parents and siblings helping each other on the challenges.”

“OHM Advisors has been seeking out ways to get younger children interested in STEM fields. We are fortunate to have had MTU reach out to us to help with this program.”

Ron Cavallaro, Vice President of OHM Michigan

Chandler Park Academy High School and UPrep Science & Math High School hosted another Michigan Tech alum, retired Lt. Colonel Otha Thornton, chair of Michigan Tech’s Diversity, Equity, Inclusion and Sense of Belonging (DEIS) Alumni Advisory Board, formed in Fall 2021. 

Lt. Colonel Otha Thornton

Thornton presented at four student assemblies as part of the outreach effort. He shared how students could find their own pathway to STEM and described STEM careers. Thornton also described highlights of his own career⁠—working directly with President Barack Obama, First Lady Michelle Obama, and Vice President Biden in the White House, along with Congress, to promote passage of the Every Student Succeeds Act. The Act supports STEM education in K-12 schools. 

Thornton’s STEM work is preceded by a 21-year career with the U.S. military. He earned the Bronze Star Medal for exceptional performance in combat operations during Operation Iraqi Freedom. His other military assignments included working with the White House Communications Agency and U.S. forces in Iraq. As the 53rd president of the National Parent Teacher Association (PTA), Thornton was the first and only African American male to serve as President in the National PTA’s 125-year history. 

Any school can access the Family Engineering Activity & Event Planning Guide to provide positive engineering experiences for K-8 students and their families. For more info, contact: Joan Chadde, jchadde@mtu.edu or 906-487-3341.

Michigan Tech SWE Section travels to Wisconsin for ‘Spring Forward’ Professional Day

Michigan Tech SWE section members and alumnae gather for a photo at Spring Forward 2022.

Nine student members of Michigan Tech’s section of the Society of Women Engineers (SWE) and their advisor, Gretchen Hein (MMET), recently attended Spring Forward, a professional development day in Kohler, Wisconsin, hosted by the SWE-Wisconsin.

Laura Kohler, Senior Vice President of Human Resources, Stewardship and Sustainability at Kohler Company gave the keynote address. She spoke about her career path, the importance of diversity, and leadership. 

Michigan Tech SWE Section members toured the Kohler Design Center after attending SWE-Wisconsin Spring Forward 2022

Mechanical Engineering alumna Jackie (Burtka) Yosick ‘14 also works at Kohler. She was on hand to discuss her work with engines and generators.

“We were also pleasantly surprised to meet Helene Cornils, director of the Advanced Development Kitchen and Bath Group at Kohler and the parent of a current Michigan Tech biomedical engineering student,” said Hein.

Two former Michigan Tech SWE Section presidents, Katie Buchalski ’19 and Andrea (Walvatne) Falasco ’12 were also present at the event. Buchlaski is an environmental engineering alumna now working at Ruekert-Mielke, where she designs municipal road and utility projects with a focus on modeling the stormwater runoff from individual sites to city-wide studies. Falasco, a mechanical engineering alumna, is lead mechanical engineer at Kimberly Clark, where she designs new equipment to make products that include Kleenex, Huggies, and Kotex. 

Numerous Michigan Tech students won SWE awards at the event, as well. One of those was biomedical engineering major Kathleen Heusser, who won a first place scholarship from the GE Women’s Network.

“Receiving the first-place 2022 GE Women’s Network Scholarship was an incredible honor,” said Heusser. “In addition to the tuition assistance it provides, the scholarship affirms my confidence in the value of my resume, my education, and my professional references, as well as my scholarship essay on what being an engineer means to me,” she explains. “The last paragraph in my essay shares how my work as an engineer will be motivated by my love of others in order to work hard–creating solutions to the problem of an individual, a company, or a society.

Another highlight of the day: Michigan Tech’s SWE section received the SWE-Wisconsin President’s Choice Award.

After the conference, each Michigan Tech student in attendance reflected on their participation and what they learned:

Aerith Cruz, Management Information Systems: “It was a great opportunity for Michigan Tech SWE members to bond and connect with one another. Being able to travel as a section and experience professional development together is a fulfilling experience. We are able to share learning opportunities and build long-lasting connections with one another. It is also incredibly fun getting to know each other while exploring the area.”

Kathryn Krieger, Environmental Engineering: “It was inspiring to hear the paths of various women, and the impacts they have made. I really enjoyed hearing about modern, female-centered design that benefits women in impactful ways–rather than the stereotypical ‘pink and shrink’ method.”

Natalie Hodge, Electrical and Computer Engineering (dual major): “Laura Kohler shared this quote in her presentation, attributed to Cassie Ho: ‘Don’t compare yourself to others. It’s like comparing the sun and the moon. The sun and the moon shine at their own time.’” 

Katherine Baker, Chemical Engineering: “I especially enjoyed attending the session, ‘Navigating Early Stage Careers: The First 10 Years’. It had a great panel that gave a ton of advice on how to advance as an engineer in the workplace.”

Maci Dostaler, Biomedical Engineering: “Women are necessary when it comes to inclusive design, which was covered during one of the sessions, ‘Breaking the Glass Ceiling’”.

Alli Hummel, Civil Engineering: “Laura Kohler talked about the importance of making time for your personal life and how that is necessary to succeed at work. She is a great example of a woman who succeeds in prioritizing both work and family life.”

Lucy Straubel, Biomedical Engineering: “I really enjoyed the whole experience. It was great to hear all the advice everyone else could give me. And making friends and memories was a bonus, too.”

Amanda West, Mechanical Engineering: “One of the things I liked most about the conference was keynote speaker Laura Kohler’s speech, where she mentioned the importance of having and maintaining relationships with your mentors, an important part in developing your career and professional skills.”

Kathleen Heusser, Biomedical Engineering: “In one session called Navigating Early Stage Careers: The First 10 Years, Tess Cain of DSM, among others, gave insightful tips about saying ‘no’ to a project or demand from management that’s just not feasible. She pointed out that how others accept your ‘no’ depends a lot on how you say it. You should use a response that includes ‘I can’t/Here’s why/Here’s what I would need to make this work’ in order to go in a doable direction with the project. And another inspiring quote, overheard during the Nonlinear Careers and the Versatility of Engineering Degrees panel, was that ‘100 percent of candidates are not 100 percent qualified.’ Raquel Reif of Kohler, in particular, stressed that already having expertise in a job field is not a necessary prerequisite to apply for the job you want.”

Tom Werner: Butterflies, Moths, and Fruit Flies in the Keweenaw

Butterly or moth? Find out during Husky Bites!

Thomas Werner shares his knowledge on Husky Bites, a free, interactive Zoom webinar this Monday, April 4 at 6 pm ET. Learn something new in just 30 minutes (or so), with time after for Q&A! Get the full scoop and register at mtu.edu/huskybites.

Dr. Thomas Werner

What are you doing for supper this Monday night 4/4 at 6 ET? Grab a bite with Dean Janet Callahan and Biological Sciences Associate Professor Thomas Werner. Joining in will be one of his former students, alumna Tessa Steenwinkel.

Tessa Steenwinkel

Steenwinkel earned her BS in Biochemistry and Molecular Biology and her MS in Biology/Biological Sciences, all at Michigan Tech. She works now as an Educational Assistant at Madison Country Day School near Madison, Wisconsin, and she will start a PhD program at Baylor College of Medicine in Houston, Texas, this fall.

During Husky Bites, they will share the most beautiful butterflies, moths, and fruit fly species of the Keweenaw Peninsula. And we’ll learn much more about their Encyclopedia of North American Drosophilids. Be sure to bring your questions!

Dr. Werner started studying insects as a childhood hobby, at age 10, when a beautiful butterfly flew in the window of his family’s 9th floor apartment in Erfurt, in East Germany. Many years later, his interest in insects is still strong, as he leads a fruit fly research lab at Michigan Tech. 

Werner’s research bridges the miniscule and the massive in an effort to better understand the mechanisms behind several unique features of fruit flies, such as the developmental genetics of color pattern formation as well as those of mushroom toxin resistance, among several other questions. Some of their research questions aim to provide insight into human cancer development.

For being so small, fruit flies have had a large impact on genetic research, thanks in great part to Dr. Tom Werner at Michigan Tech.

Werner also teaches courses on general immunology, introduction to genomics, developmental biology, and he used to teach genetics and with a genetic techniques lab. He’s been bestowed with the state-wide Michigan Distinguished Professor of the Year Award 2021 and won Michigan Technological University’s Distinguished Teaching Award twice (both in the non-tenured and the tenured categories).

Callout quote:

“Werner is the epitome of the scholar-teacher. His enthusiasm in the classroom is remarkable, as is his devotion to mentoring more than 100 undergraduate researchers,” says David Hemmer, dean, College of Sciences and Arts.

“Thinking about the long winters here, I would call teaching a powerful antidepressant.”

Dr. Thomas Werner

Steenwinkel started at Michigan Tech in the fall of 2017 by joining the Pavlis Honors College. She majored in Biochemistry and Molecular Biology-Biological Sciences with a minor in Pharmaceutical Chemistry. Originally from the Netherlands, Steenwinkel has lived in the United States since she was 12 years old.

“On Michigan Tech’s annual Preview Day in March 2017, Tessa visited my lab at Michigan Tech as a high school student,” Werner recalls. “I offered her a job on the spot, because I felt that she would become the best student I have ever mentored. And I was correct about that: As my undergraduate research assistant and master’s student, she has published two books and 10 papers with me, while she won 8 university-wide and national awards!”

“When I walked into the lab, I knew that this could be the place for me,” adds Steenwinkel. “After getting started at Tech, I immediately reconnected with Dr. Werner and essentially started working in the lab the next day. I worked there for over four years, working alongside grad students, leading my own project, and managing the lab even when Dr. Werner went on sabbatical in Singapore. I was always so grateful to have Dr. Werner as a mentor.”  

During her first year, Steenwinkel went from assisting in Werner’s research lab to becoming a co-author on his book, Drosophilids of the Midwest and Northeast, with John Jaenike, a professor of biology at the University of Rochester. The three later published a second book together “Drosophilids of the Southeast”, published under the umbrella name “The Encyclopedia of North American Drosophilids.” Both books welcome researchers, teachers, and young students alike into the amazing world of flies and the diversity of their potential use in research.  

The Encyclopedia of North American Drosopholids, Vol 1: covers the Midwest and Northeast.
The trio’s second book covers the Drosophilids of the Southeast.

The books also include a significant outreach component that speaks to young children about science and nature in the form of a bedtime story about fruit flies written by Steenwinkel. Open-access books, they can be downloaded for free here and here.

While at Michigan Tech, Steenswinkel became the first recipient of the Soyring Foundation Scholarship. John Soyring, Tech alumnus and Pavlis Honors College External Advisory Board member, established the scholarship for Pavlis Honors students expressing interest in research and innovation related to water quality management, renewable energy, or solutions to prevent and cure cancer. 

Prof. Werner, what sparked your interest in biology, fruit flies and genetics?

I am a biologist by heart. It all started in former East Germany when a butterfly entered my bedroom on the ninth floor in the middle of the city. On that July morning in 1981, I started collecting butterflies as a 10-year-old boy. This moment defined my life, and today I am associate professor of genetics and developmental biology.

Family?

I have a wife Megan, a daughter Natalia (10), and two sons: Oliver (7) and Oscar (5).

Any hobbies? Pets? What do you like to do in your spare time?

As a hobby, I collect and rear butterflies and moths. I like camping (and collecting fruit flies on these trips for my next field guides). I also have a dog named Frosty, who also likes camping.

Tessa, what sparked your interest in science?

My brother with Down Syndrome first got me interested in biology. From there, I started to learn about genetics, development, and diversity. This is what brought me to Michigan Tech and to start working in Dr. Werner’s lab, where he was using fruit flies to model human cancer. When I started working there, he had just published his first book on fruit flies, and I was immediately fascinated by the beauty and diversity of these small bugs. 

Hometown, family?

I’m originally from the Netherlands. I grew up there with my parents and two younger brothers. In 2012, we moved to Baton Rouge, Louisiana, before moving to Madison, Wisconsin, in 2014. In 2017, I decided to start college at Michigan Tech, where I obtained my undergraduate and master’s degrees.

Any hobbies or pets? What do you like to do in your spare time?

When I’m not in the lab, I enjoy running outside and teaching ski lessons to the local kids. When you live in Houghton, you have to make the best out of it. I’m currently getting ready to start my PhD. I currently have two very enthusiastic turtles. 

Fernando Ponta: The Wind Beneath My Wings/Sails/Turbines

“Since the emergence of the first windmill in ancient times, through the windmills of the middle ages, to the high-tech wind turbines of today, there has been an intimate relationship between the evolution of wind rotors and sailing rigs,” says Fernando Ponta.

Fernando Ponta shares his knowledge on Husky Bites, a free, interactive webinar this Monday, 3/28 at 6 pm. Learn something new in just 30 minutes or so, with time after for Q&A! Get the full scoop and register at mtu.edu/huskybites.

Fernando Ponta

What are you doing for supper this Monday night 3/28 at 6 ET? Grab a bite with Dean Janet Callahan and Fernando Ponta, the Richard and Elizabeth Henes Professor of Wind Energy. Joining in will be one of Dr. Ponta’s mechanical engineering PhD students, Apurva Baruah, who brings industrial experience to his research with Dr. Ponta. Baruah is also a member of the crew on Dr. Ponta’s J-80 sailboat, the Avanti Bianc.

“There’s no better way to understand the wind than trying to harness its power on sails,” says Baruah.

The Avanti Bianc: “I’ve been Apurva’s boat skipper since 2015, and his PhD advisor since 2017,” says Dr. Fernado Ponta. “We’re both part of Michigan Tech’s ‘Wind-Warriors’ team.”

During Husky Bites, Ponta and Baruah will explain the evolution of wind power technology from its beginnings until the current development of next-generation, advanced, mega-scale wind turbines. One aspect of their research involves modeling the wakes of many wind turbines operating in a huge wind farm. They’ll discuss the importance of understanding and modeling these wakes in order to optimize both offshore and inland wind farm performance.

Apurva Baruah

“We’ll also share a brief review of our collaborative work with Sandia National Labs,” adds Baruah. “That includes the novel, aeroelastic-vortex-lattice codes we use to study cutting-edge wind energy technologies.”

At Michigan Tech, Ponta’s research team seeks to understand the detailed physics of a wind-turbine–from the rotor structure and aerodynamics, to turbine control and drivetrain electromechanics. 

“Since the emergence of the first windmill in ancient times, through the windmills of the middle ages, to the high-tech wind turbines of today, there has been an intimate relationship between the evolution of wind rotors and sailing rigs,” he says. “Ancient windmill designs used the principle of aerodynamic drag to produce the forces acting on the blades in the same manner that square rigs used drag to propel ships.”

“In a period of several centuries, sailing rigs progressively evolved into the use of sail arrangements that propel ships via the generation of lift force, which not only give ships the great advantage of going faster in the same conditions, but also of sailing partially into the wind,” adds Ponta. “All this technological experience translated into the evolution of wind rotors that also use lift as their physical mechanism for torque and power generation. In the case of a wind rotor, it has resulted in a dramatically higher efficiency of the conversion process from the kinetic energy of the wind, into mechanical power on the shaft.”

This parallel development was fundamental to the evolution of current wind energy technology, says Ponta. “The basic concept of the lift-driven wind rotor, conceived in the late middle-ages, is essentially the same as the high-tech wind turbines of today. The inherent energy efficiency of the lift generation process versus the generation of drag—with all its associated frictional losses—is the physical underpinning of this fundamental progress.”

Wind turbine blades average almost 200 feet long, and turbine towers average 295 feet tall—about the height of the Statue of Liberty.

Dr. Ponta and Apurva promise to interpret and explains these models for us during Husky Bites.

In modern times, a similar parallel can be traced between the optimization of the kinds of aerodynamic surfaces used in aeronautics, and the refinements of the latest generations of high-tech wind turbines, notes Ponta.

Over a period of years Ponta has developed a novel aeroelastic model for optimizing the rotor blades used in “smart” turbines and the collective control strategies of mega wind farms. The resulting modeling tool is now being applied by Sandia National Labs (SNL) for the study of the advanced lightweight rotors of their National Rotor Testbed (NRT) project. The result is a complete picture of how a wind turbine behaves under various conditions. Ponta’s modeling can be used to design blades and simulate the interaction of multiple wind turbine wakes in a wind farm, as well—particularly, the thousands of meters long wakes of the utility-scale megawatt turbines of today, and the super-turbines of tomorrow.

Dr. Ponta and his daughter enjoy skiing at Mont Ripley, Michigan Tech’s own ski area.

Dr. Ponta, how did you first get into engineering? What sparked your interest?

I’ve always been fascinated with science and technology, even when I was a kid. In my high school years, I attended what in my country of origin is called an industrial college, with a specialty in electronics. I started as a naval and mechanical engineering student, and then I decided to switch to a full career in mechanical engineering. With the years, I focused more and more into computational and theoretical fluid mechanics, in particular as they apply to the study of wind turbines and other renewable energy systems.

Hometown?

I was born in the city of Buenos Aires, Argentina, even though my family lives now in the Patagonia region. Curiously, they live at the same latitude that we are here in Houghton, but in the southern hemisphere. That is, the same temperatures but with a six-month shift! 

The Avanti Bianc, on Traverse Bay

What do you like to do in your spare time?

In summer, sailing and swimming. I own a sailboat which I skipper regularly in the regattas of the Onigaming Yacht Club, of which I’m a member of the directory board. In winter, I ski a lot at Mont Ripley. Alpine skiing is my favorite sport, and I’ve been skiing since I was in my teens in the Andes range in Patagonia. I lift weights all year round.

Apurva, how did you first get into engineering? What sparked your interest?

Apurva is passionate about aviation, too. “Since 2017 I’ve been visiting the EAA AirVenture, a summer air show and gathering of aviation enthusiasts in Oshkosh, Wisconsin at Oshkosh.”

I’ve been fascinated with aircraft from a very young age. I had an amazing physics teacher throughout grade school and figured engineering was the path forward in order to work with airplanes.

During my undergrad years, I just naturally ‘flowed’ towards fluids and aerodynamics. After a few years working in industry, I decided to pursue a graduate degree at Tech. Our research in wind turbines and their wakes in a wind farm is a perfect blend of my interests.

Hometown?

I was born and raised in Mumbai, India. My mom’s terrified yet excited to visit the Keweenaw! She frequently catches our blizzard-y days by watching the HuskyCam feeds!

Any hobbies?

Thanks to Dr. Ponta, I’ve found an immense passion for sailing. It’s an important aspect of our summer ‘research’. I also frequent Michigan Tech’s Student Development Center, aka “the SDC” for racquet sports, including tennis, badminton, and table tennis, and the shooting range. I’m the range safety officer for Michigan Tech’s Competition Rifle team.

Sarah Green: Glasgow—Michigan Tech Agents of Change

Michigan Tech delegation, colleagues and friends at COP26 in Glasgow

Sarah Green shares her knowledge on Husky Bites, a free, interactive Zoom webinar this Monday, March 21 at 6 pm ET. Learn something new in just 30 minutes (or so), with time after for Q&A! Get the full scoop and register at mtu.edu/huskybites.

Dr. Sarah Green: “The ultimate challenge to understanding how things work is to consider the whole Earth as a system of physical, biological and human processes.”

What are you doing for supper this Monday night 3/21 at 6 ET? Grab a bite with Dean Janet Callahan and Professor Sarah Green, interim chair and professor of Chemistry. Last November, six Michigan Tech students and three alumni helped lead events and a press conference at the 26th United Nations COP26 event in Glasgow, Scotland. The group was accompanied by Green, whose interests include all aspects of environmental chemistry, from molecular analytical methods to global climate change. 

The group’s effort was part of the Youth Environmental Alliance in Higher Education (YEAH), a multidisciplinary research and education network involving 10 universities. Formed in 2019 with support from the National Science Foundation, YEAH prepares students to engage on climate-related issues across disciplines and cultures—and to be part of the climate solution as scientists and emerging leaders. 

On the trip were Jessica Daignault, who earned her PhD in Environmental Engineering at Michigan Tech in 2021, and current mechanical engineering PhD student Ayush Chutani. During Husky Bites we’ll hear about their experiences at COP26—and what comes next.

Daignault is now a professor civil engineering at Montana Tech. Chutani is conducting doctoral research at Michigan Tech, testing new solar panel coatings designed to shed snow.

We’ll also get a head start in celebrating United Nations World Water Day, coming up on Wednesday March 22, 2022. At Michigan Tech, World Water Day celebration at the Great Lakes Research Center for a week!

Ayush Chutani: “For me, finding solutions to global problems is as important as our approach to finding them.”
Dr. Jessica Daignault: “There must be transparency and accountability in the negotiation process, and the voices of minority populations must be heard.”

“We are linked to our environment by flows of atoms, and some of them are causing planet-wide changes,” notes Green. “Chemical flows help visualize the big picture of climate change and the human impacts. The ultimate challenge in understanding how things work is to consider the whole Earth as a system of physical, biological and human processes,” she says.

Green first joined the Department of Chemistry at Michigan Tech in 1994, then served as department chair for the next nine years. Her research includes carbon cycling in the Lake Superior basin; origin and fate of organic carbon in terrestrial, lake, and marine environments, response of aquatic systems to climate change; integration of biological, geological, physical, and chemical data for understanding of global cycles, and the communication of climate change science.

At Michigan Tech Green was instrumental in several major climate-related environmental monitoring efforts, beginning with KITES, an NSF-funded project that spawned many subsequent environmental monitoring efforts in the upper Great Lakes. The work continues today with the Army Corps of Engineers, the Alliance for Coastal Technologies and NOAA’s Great Lakes Observing System (GLOS). 

In 2013 she was named a Jefferson Science Fellow by the US State Department, and spent a year working in the Bureau of East Asia-Pacific Affairs. Then, from 2015-2019, Green served as co-chair for the Scientific Advisory Panel on the Sixth Global Environmental Outlook (GEO-6), United Nations Environment Programme.

Green’s work with the State Department and with UN Environment has given her direct experience at the science-policy interface. “Perhaps the most important aspect of policy is listening carefully to identify the key concerns of all players,” she says. “My work with policy has also exposed me to a few of the many smart and dedicated people who are striving to improve the world.”

Green has brought both experiences back to her teaching, especially in her Climate Science and Policy course at Michigan Tech. She also teaches a course on Green Chemistry. 

“I first met Dr. Sarah Green while I was a student in her climate policy course during graduate school,” says Daignault. “Since then I have had the privilege of attending two United Nations COP meetings with her and other MTU delegates.”

“I was a student in Dr. Green’s course on climate policy last semester,” adds Chutani. “I was fortunate to attend COP26 in person last year. I hope to go next year as a part of the MTU delegation.”

“We have the technology to drastically slow global warming,” says Dr. Sarah Green.

“Climate change is an enormously multifaceted problem,” says Green. “Many actions are urgent, so removing impediments to action may be the most critical starting point. Innumerable opportunities are emerging and many would flourish if obstacles were removed.”

“We have the technology to drastically slow global warming,” she says. “The best case scenario is that we collectively commit to deploying that technology, and that we skillfully manage potential economic and social disruption that can result from such large scale changes. The faster we act, the better the chance of keeping global temperatures within tolerable limits.” 

Adds Green: “The worst-case scenarios are bad—and unpredictable. Humans have no experience with a climate warmer by 2 degrees Celsius than the one where civilization developed.”

“Imagine taking the entire population of Earth to a new planet with unknown weather patterns, unknown ecology, new disease pathways and unpredictable crop yields.” 

Dr. Sarah Green

“People can contribute to climate solutions by working on myriad fronts, including new energy systems, cultural change, modern materials, ecology, art, hydrology, communication, transportation systems, philosophy, chemistry and especially cross-disciplinary exchanges.”

Dr. Green, how did you first get interested in chemistry and Earth system science?

I have always wanted to understand how things work. My dad encouraged me to take things apart to figure them out. In college, I spent a few months replacing the engine in my car and saw how mechanical, electrical and chemical processes all join in a coherent system.

Chemical reactions are themselves tiny systems that work when atoms and molecules line up in the right places with the right energies and electron arrangements to transform.

My graduate work focused on carbon-containing molecules in the ocean, which led me toward what is now known as earth system science.”

What do you like best about your work now?

I really like collaborating with people from diverse fields because I always learn new perspectives on the world, new tools to understand it and new connections between its parts.

“Climate change cannot be addressed without considering social justice, gender equality, capitalism, freshwater and ocean resources and impacts to biodiversity.”

Dr. Jessica Daignault

Dr. Daignault, how did you first get into engineering? What sparked your interest? 

Michigan Tech’s Leading Scholars program was my gateway. I wasn’t sure which specific engineering discipline I was going to pursue until I got to campus my first year, where I discovered Environmental Engineering. I was excited to find a program that combined my aptitude for math and science with the physical, chemical, and biological processes related to the environment. 

Hometown, family?

I grew up in Marquette, Michigan on a small hobby farm. I have a deep love for the Upper Peninsula. I have a dog named Smith and a horse named Diams. 

What do you like to do in your spare time?

I love to get outside and adventure on horseback, bicycle, or foot. 

I am interested in energy equity and just transitioning towards a sustainable future.

Ayush Chutani

Ayush, how did you first get into engineering? What sparked your interest?

My engineering interests stem back to a young age from watching Nat Geo and Discovery Channel shows. I always wanted to be a creator and inventor and pretty much started with mechanical engineering; my journey started with aerospace engineering. Still, I later transitioned to renewable energy, sustainability, and climate change during my masters. For me, finding solutions to global problems is as important as our approach to finding them. Also, I am interested in energy equity and just transitioning towards a sustainable future. 

Hometown? And what do you like to do for fun?

I grew up in Faridabad, India, in the National Capital Region. I like to draw, sketch and cook in my free time. I also spend considerable time enjoying popular fiction, including movies and games. I try to look out for unique foods and interesting local stores when I travel.

Reflection and Perspectives from Inside COP25

Caryn Heldt: The Making of a Vaccine

Caryn Heldt shares her knowledge on Husky Bites, a free, interactive Zoom webinar this Monday, March 14 at 6 pm ET. Learn something new in just 30 minutes (or so), with time after for Q&A! Get the full scoop and register at mtu.edu/huskybites

“Our goal is to bring biotherapies to market faster,” says Dr. Caryn Heldt.

What are you doing for supper this Monday night 3/14 at 6 ET? Grab a bite with Dean Janet Callahan and Chemical Engineering Professor Caryn Heldt, to learn how different vaccines are made. Heldt, the James and Lorna Mack Endowed Chair of Cellular and Molecular Bioengineering, will talk about the different types of vaccines, how they are created and designed, and the FDA approval process. 

Caryn Heldt

Joining in will be one of Dr. Heldt’s former students, Dylan Turpeinen, who worked as an undergraduate and graduate researcher in the Heldt Bioseparations Lab at Michigan Tech. Dr. Turpeinen earned his BS in 2016, and his PhD in 2020, both in Chemical Engineering at Michigan Tech. He’s now a downstream process development scientist at the Florida-based biopharmaceutical company Resilience (formerly Ology Bioservices). In his role, Dr. Turpeinen operates and optimizes purification unit operations to produce vaccines.

Heldt is an alumna, as well. She graduated from Michigan Tech in 2001 with a Bachelor’s degree in Chemical Engineering and Chemistry. She earned a Masters in Chemical Engineering in 2005 and her PhD in Chemical Engineering in 2008, both from North Carolina State University. After post-doctoral studies in chemical engineering at Rensselaer Polytechnic Institute in 2010, she joined the chemical engineering faculty at Michigan Tech. Then, in 2015, Heldt won a prestigious NSF CAREER Award, which boosted her efforts and focus on vaccine research and development. She’s a member of the American Chemical Society, the American Institute of Chemical Engineers, the Society of Biological Engineers, and the Biophysical Society.

Pictured: the ultrastructural details of an influenza virus particle, or “virion”. Dr. Heldt is PI on a joint research project with Johns Hopkins University, funded by the FDA, “Integrated and Continuous Manufacturing of an Influenza Vaccine.”

Heldt teaches both undergraduate and graduate classes at Michigan Tech. Her lab, the Heldt Bioseparations Lab, is busier than ever, with seven graduate and five undergraduate students and two postdocs⁠—her vaccine research dream team. “Our lab focuses on the science of viral surface interactions and applies it to vaccine manufacturing and purification,” she explains. “We are interested in how viruses interact with different surfaces and chemistries. This could be important in how viruses infect cells, but we focus on how we can change surfaces to improve purification and manufacturing of viral therapies.”

Dylan Turpeinen

Turpeinen started out in the lab with Dr. Heldt as undergraduate researcher, fabricating and testing graphene-based electrochemical biosensors for rapid protein detection. He shared his enthusiasm for biosensors with middle and high school students the summer after he graduated with his BS, teaching at Michigan Tech’s Summer Youth Program (SYP) and then started work on his master’s degree, conducting graduate research on biosensors to detect malaria.

We are interested in how viruses interact with different surfaces and chemistries.

Turpeinen’s research then shifted to developing and testing a gold nanoparticle aggregation assay for virus detection, which could be used to ensure surface cleanliness on cruise ships, at hospitals or doctor’s offices between patients. His doctoral dissertation was entitled, “Development of Detection and Purification Strategies for Viral Products,” successfully defended (virtually due to the Pandemic) in July 2020.

Observing these chemical reactions in a test tube sometimes reminded him of a sunset: “The gold nanoparticles are the sun that start above the lake displaying a red-ish pink color and as the sun begins to set behind the lake, the color changes to a deep purple. When the sun is set, only the crisp blue color of Lake Superior is left behind.”

“Integrating graduate and undergraduate training in the lab inspires and guides the next generation of engineers. It also enhances our research.”

Caryn Heldt
A day in the life in the Heldt Bioseparations Lab

Dr. Heldt, how did you first get into engineering? What sparked your interest?

Ever since grade school, I planned on being an engineer. At first, I wanted to work at mission control at NASA. Later, I wanted to make a difference in people’s lives. My mom and sister are nurses, and while I didn’t want to be a medical doctor, making medicines really intrigued me. Now as an engineer I can still make a difference without working directly with patients. 

“A few years ago my son had the Grand Champion chicken in the Houghton county Fair!”
Looking good!
Dr. Heldt is a quilter!

Hometown, family?

I grew up in Pinconning, Michigan. My dad dropped out of school in 8th grade to help on the family farm and my mom has an associate’s degree in nursing. They instilled in me the importance of education and pushed me to get a bachelor’s degree. They were a little surprised when I took it so far as to get a doctorate degree. 

What do you like to do in your spare time?

I live in Atlantic Mine with my husband Gary and our three children. At home we have about 25 chickens (give or take a few) that give us fresh eggs. I enjoy quilting in my spare time. I’ve even started quilting viruses and microscopes, so my love for science is bleeding over into my hobbies. As a family, we downhill ski, snowshoe, and camp. I’ve also served on the Michigan Tech Preschool board, and was a FIRST Lego League coach, too.

“Gold nanoparticle size increase reminds me of a sunset over Lake Superior.”

Dylan Turpeinen, spoken as a chemical engineering PhD student at Michigan Tech

Dr. Turpeinen, how did you first get into engineering? What sparked your interest?

As a kid, I was always using Lego blocks to build anything I could imagine—houses, planes, and spaceships. When I got older, I found myself thinking about how and why something worked. I knew I needed to learn techniques to figure out how. When I visited Michigan Tech in high school, the professors I talked to made me very excited about Chemical Engineering.They explained how it was the “jack of all trades” of engineering. I knew pursuing an engineering degree would teach me the techniques I needed in order to figure out most things at a base level. To this day I deep-dive into any project I am interested in to understand how it works.

Ellie and Momo: they get along great!

Hometown, family?

I was born in Orlando but grew up in Houghton where I stayed for almost 15 years. I currently live in sunny Gainesville, Florida with my wife LiLu Funkenbusch and our two fur babies, Ellie (dog) and Momo (cat).

Any hobbies?

I like woodworking, PC gaming, and visiting local breweries to enjoy any and all IPAs (aka India Pale Ales). I also enjoy making various improvements to our new house.

Hajj Flemings: Looking Deeper

Hajj Flemings earned his BS in Mechanical Engineering in 1996 and his MBA at Lawrence Tech in 2003: “The educational experience gave me an appreciation for adapting and prepared me for the future.”

When Hajj Flemings looks at a city, he sees more than the streets and buildings. Blessed with an uncanny gift for looking deeper into places, people, and cultures, Flemings invites those around him to bring their light and search with him for the essential. 

When he graduated from Michigan Tech with a bachelors degree in mechanical engineering, Flemings was well prepared to adapt to his new work environment on the factory floor at Ford—and begin refining the key concepts for his future endeavors. He went on to start Brand Camp University, an educational platform that is preparing people for the future of work, and Rebrand Detroit, a civic design and brand project and multi-disciplinary collaboration with the residents, community stakeholders, and local government to change cities—starting with his home city of Detroit.

At Ford Flemings was a quality engineer responsible for 20 percent of their aftermarket parts, including remanufactured engines and catalytic converters. 

“I was giving instructions to people who worked on the line longer than I had been alive, but it was through that role I gained an appreciation for making complex concepts simple, while learning to communicate with people who knew more about the core job than I did,” he shares. “It helped me prepare to pivot on my career when the time was right.” 

“I knew on day one that I didn’t want to be an engineer my whole life, but I also knew the degree taught discipline and trained you on how to solve problems.”

Hajj Flemings 

Being a creative at heart, Flemings was writing a branding book and establishing his business while preparing for an exit plan from Ford. “Quality engineering continues to influence what I do today to think beyond aesthetics. It means creating something that works, makes business sense, and is accessible and sustainable,” he explains. “In everything I do, I am thinking about the entire design process journey and how the product meets reality.” 

There is a seasonality of products and people. Products have a lifecycle just like people who leave their positions, notes Flemings. “When creating, we need to ensure we have everything on the ground needed to create it, know how to put it in the hands of the consumer, and make sure there is a documentation trail, so we can hand it off to the next person.”

The grit and determination he gained working through challenging coursework at Michigan Tech has enabled Flemings to lead rebranding efforts for cities across the country and also in Haiti. Looking back on his career successes, Flemings says he feels inspired.

 “The greatest opportunity I have in my role is to learn from others’ stories, develop relationships, and to be able to write the stories of businesses and cities to impact their culture.”
