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.”

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.

TECH SCEnE Offers the Best of Both Worlds in Michigan’s Upper Peninsula

Keweenaw Bay Indian Community tribal members share their knowledge, wisdom, and culture with TECH SCEnE REU students. Apply for TECHSCEnE Summer 2022 by March 15 at https://www.techscene.mtu.edu. Tentative program dates are June 3, 2022- July 29, 2022. Tribal college, community college or university students, women and students from underrepresented backgrounds are all encouraged to apply.

What are you doing this Summer 2022? Want to combine cutting-edge engineering research with direct community involvement and impact? With a generous stipend, travel allowance, plus all expenses paid for 8 weeks?

Samantha Haynes, future biomedical engineer, spent 8 weeks as a TECH SCEnE REU researcher last summer.

Biomedical engineering student Samantha Haynes decided to immerse herself in something entirely new via TECH SCEnE, a National Science Foundation Undergraduate Research Experience (REU) at Michigan Technological University. Haynes came all the way from Arlington, Virginia, where she studies biomedical engineering at Virginia Tech.

The 8-week, all-expense paid program offered at Michigan Tech is called TECH SCEnE (short for Technology, Science and Community Engagement in Engineering). Haynes stayed on campus, went on outdoor trips throughout the Keweenaw Peninsula, guided by the Keweenaw Bay Indian Community, and conducted hands-on research in campus labs alongside a faculty mentor.

TECH SCEnE research projects include water quality testing for heavy metal contamination, smart adhesives for underwater applications, remote monitoring and mobile robots, simulating daylight for hatcheries, and in vitro modeling of the impact of heavy metals.

Samantha is seventh from the left. TECH SCEnE stands for Technology, Science and Community Engagement in Engineering

In addition to hands-on laboratory experience, Haynes and her fellow students took plenty of field visits to the beautiful lakeshores of Lake Superior and Keweenaw Bay. Application deadline for Summer 2022 is March 15. Tentative program dates are June 3, 2022- July 29, 2022.

This year is forecast to be outstanding for viewing the Northern Lights in the Upper Peninsula of Michigan. Located just 20 minutes or so from the Michigan Tech campus, McLain State Park on Lake Superior is a great potential viewing spot!

Haynes pioneered research on heavy metal contamination in the soil and wild rice beds around the Keweenaw last summer as an undergraduate researcher taking part in TECH SCEnE. She also worked alongside members of the Keweenaw Bay Indian Community (KBIC), her fellow REU students, and other volunteers to plant over 75 trees, build hoops houses, harvest foods, and upkeep a large community garden, the tribe’s People’s Garden.

Wild rice, known as manoomin, the good berry, is both a spiritual and nutritional staple of the Keweenaw Indian Community.

Samantha, what did you like most about TECH SCEnE?

I applied to TECHScENE REU because I thought the internship was very unique. I was excited to have the opportunity to work in Michigan and learn about the local Indian community. I personally value diversity and learning about different communities very much, so I appreciated that this type of internship existed. I’m also passionate about creating positive social change, helping to protect the environment, and using science to bridge gaps in education and educate the public on pressing issues.

What was the best part?

Samantha and fellow volunteers tending to plants in one of the many Hoop Houses of the Keweenaw Bay Indian Community People’s Garden

Out of all the experiences activities we did throughout TECH ScENE, building relationships with my fellow peers, mentors, and the Native American community was my favorite part.

What was the most challenging aspect?

The unlearning process of everything I thought I knew about Native Americans. We participated in weekly workshops to unlearn false, preconceived ideas and to learn factual information about Native American tribes and tribal members, especially those we were working with as part of TECH SCEnE. 

“Boozhoo! Welcome to our wellness trail,” says this sign, located on Keweenaw Bay Indian Community tribal land. Take a moment to learn a few words of the Ojibwe language. “Miikaans means “trail”. “Aki” means Earth. And “boozhoo!” means “greetings!” or “hello!”

What next? What are your future plans?

Currently I am a junior in biomedical engineering, so the next step is to secure another internship for summer 2022, in order to gain more experience. Once I graduate, I plan to start working and possibly consider graduate school after a year or two.

Samantha’s final presentation, with her TECH SCEnE research mentor, Professor Rupali Datta

Are you an adventurous college student? Want to learn how to use science and technology to benefit both the community and the environment? Apply to TECH SCEnE by March 15. Tribal college, community college or university students, women and students from underrepresented backgrounds are all encouraged to apply. Learn more and apply for free at techscene.mtu.edu.

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.”

LEED (Leadership in Energy and Environmental Design) is the most widely used green building rating system in the world. Available for virtually all building types, LEED provides a framework to design, construct and operate healthy, highly efficient, cost-saving, green buildings.

Michigan Tech’s Joe Azzarello is one of the founders of the US Green Building Council and has led LEED training workshops throughout the United States, Mexico, South America, China, Thailand, Hong Kong, Singapore and Vietnam. Photo courtesy of Kohler Co.

Are you a student, faculty member or staff at Michigan Tech? If so, you are invited to prepare for, and when ready, take the LEED Green Associate exam. The prep will take place during two sessions, at a low cost, right here at Michigan Tech, with expert training from an original founding member of the US Green Building Council—Michigan Tech alumnus Joe Azzarello.

The LEED exam prep training at MTU will take place over two days. Azzarello will teach on campus in two 5-hour sessions, from 12-5 pm on both Sunday, March 20 and Sunday, March 27. The room is ChemSci 211. Those who cannot attend in person can attend via Zoom. LEED exam training costs $80.00, which includes notes and printed materials. Attendees are expected to purchase their text book, which varies in cost from $73.00 to $115.00, depending on e-book or vendor.

“Attendees will be well trained in what to study for the exam to become accredited as a LEED Green Associate,” notes Azzarello. “Then they must register, take, and pass the LEED GA exam from the USGBC at a later date in order to receive accreditation. The complete costs for LEED Green Associate accreditation varies. The USGBC website provides information on the Steps to Become a LEED Green Associate.

There is no need for a college degree. “Literally anyone can take the course if they can read, memorize some information, and add and subtract,” says Azzarello.

The USGBC LEED Green Associate exam measures general knowledge of green building practices and how to support others working on LEED projects. “The exam is ideal for those new to green building. It’s an accreditation that can enhance your current endeavors, and also open doors to new career opportunities,” Azzarello explains. “LEED accreditation is a globally recognized symbol of sustainability achievement and leadership.”

Depending on interest, Azzarello may offer more LEED training to Michigan Tech students, faculty and staff. Next up would be the LEED Accredited Professional Exam for individuals who actively work on green building and LEED projects.

Azzarello is a LEED AP® and a registered and active USGBC® Faculty™. He is licensed to instruct multiple USGBC workshops and has led workshops throughout the United States, Mexico, South America, China, Thailand, Hong Kong, Singapore and Vietnam. He truly enjoys instructing and sharing his 20-plus years of USGBC and LEED experience while bringing new professionals into the green building movement.

Azzarello earned his BS in Mechanical Engineering from Michigan Tech 1978 and an MS in Environmental Engineering in 1996 from Wayne State University. He is an adjunct instructor in the Department of Chemical Engineering, and also serves as advisor to Michigan Tech’s Alternative Energy Enterprise team. 

“I am at the stage of my life now where it is time to give back to Michigan Tech and the community and am in the position to do so,” says Azzarello. “Without a degree from MTU I am not sure how my life would have turned out. I feel very fortunate to be able to give back.”

Prior to joining Michigan Tech, Azarello retired from Kohler Co. as a senior staff engineer focused on sustainability, directing the company’s green building efforts and serving as a global consultant to customers developing green building projects. With decades spent in the environmental field, Azzarello’s resume touts myriad experiences with recycling, energy efficiency, sustainability, co-generation, marketing, sustainable product design and green building design, and construction programs for several Fortune 500 companies, along with multiple smaller organizations as a sustainability consultant. He also served as Yellowstone National Park’s green building consultant. 

Azzarello has been a part of the green building movement since its beginning. He served on the USGBC’s first Board of Directors as Vice Chairman, actively involved as a Board member during its formative years. He helped pave the way for LEED by participating in the Beta testing of the newly developed green building guidelines that became known as LEED v1.0. Read Joe Azzarello’s full bio.

Research links continents to key transitions in Earth’s oceans, atmosphere and climate

A recent study led by University of Wisconsin Oshkosh geologist Timothy Paulsen advances the understanding of the role continents have played in the chemical evolution of Earth’s oceans, with implications for understanding atmospheric oxygenation and global climate oscillations. The research team includes Chad Deering and Snehamoy Chatterjee, Dept. of Geological and Mining Engineering and Sciences at Michigan Technological University, and Jakub Sliwinski and Olivier Bachman, Institute of Geochemistry and Petrology, ETH Zurich.

Tim Paulsen

The team’s research article, Continental Magmatism and Uplift as the Primary Driver for First-Order Oceanic 87Sr/86Sr Variability with Implications for Global Climate and Atmospheric Oxygenation, is featured on the cover of the February issue of GSA Today, published by the Geological Society of America.

The team analyzed a global database of the chemistry of tiny zircon grains commonly found in the Earth’s continental rock record. “We use zircon because it is very resistant to weathering and breakdown over a wide span of environmental conditions and can be dated accurately,” Deering explains. Zircon grains are about the size of the width of human hair; typically around 150microns.

Chad Deering

“Oceans cover 70% of Earth’s surface, setting it apart from the other terrestrial planets in the solar system,” said Paulsen, the lead author on the paper. “Geologists have long recognized that there have been profound changes in ocean chemistry over time.”

Yet there are significant questions about the drivers for changes in ocean chemistry in Earth’s past, especially associated with the ancient rock record leading up to the Cambrian explosion of life approximately 540 million years ago.

“Continents tend to be worn down by weathering and rivers tend to transport this sediment to the oceans, leaving scattered puzzle pieces for geologists to fit together,” said Deering, associate professor of Geological and Mining Engineering and Sciences at Michigan Tech, and coauthor on the paper. “There is increasing evidence that important pieces of the puzzle are found in the ancient beach and river sediments produced through continental weathering and erosion.”

The researchers’ findings, based on an analysis of an exceptionally large zircon data set from sandstones recovered from Earth’s major continental landmasses, may signify key links in the evolution of the Earth’s rock cycle and its oceans.

GSA Today highlights articles that appeal to a broad geoscience audience. On the cover:

“Our results suggest that two major increases in continental input from rivers draining the continents were related to the break-up and dispersal of continents, which caused increased weathering and erosion of a higher proportion of radiogenic rocks and high-elevation continental crust,” Paulsen said.

“Both episodes are curiously associated with snowball Earth glaciations and associated steps in oxygenation of the atmosphere-ocean system. Geologists have long recognized that oceans are required to make continents. It would appear based on our analyses that the continents, in turn, shape the Earth’s oceans, atmosphere and climate.”

This study was funded by University of Wisconsin Oshkosh’s Faculty Development Program.

Dean’s Teaching Showcase: Timothy Eisele

Tim Eisele
Tim Eisele

Dean Janet Callahan has selected Timothy Eisele, associate professor in the Department of Chemical Engineering, as our seventh 2022 Deans’ Teaching Showcase member.

Eisele will be recognized at an end-of-term event with other showcase members and is also a candidate for the CTL Instructional Award Series.

Eisele was selected for his record of engaging students in the classroom through hands-on experiential learning and relating material to real-world examples and his own research.

Among the variety of classes taught by Eisele are courses focused on the extraction of metal ions from fluids. While these align with his research expertise, available textbooks often don’t include the latest research in the field. Eisele fills that gap by working continuously to improve his class notes and handouts each year. He also develops unique in-class demonstrations and laboratories that elucidate these current topics. His priority is to make these accessible and connected to his students’ world. For example, in Hydrometallurgy/Pyrometallurgy, there is a copper electrowinning experiment students are able to conduct entirely at home. Eisele’s philosophy focuses on helping students develop a deep understanding of the subject material, so they can internalize what they are learning and remain engaged.

Callahan especially appreciates this ability to find and do science outside of the lab. “Dr. Eisele finds experiments to do — even in his own backyard,” she notes. “I recently had him as a guest for Michigan Tech’s Zoom webinar series, Husky Bites, where he relayed how he has developed a way to extract manganese and iron by using naturally occurring anaerobic iron-dissolving organisms.”

Chemical Engineering chair Pradeep Agrawal highlighted two other distinguishing features of Eisele’s teaching: his passion and genuine concern for engaging students. “The students readily sense his enthusiasm for the subject matter and his desire to engage them with the material,” writes Agrawal, who emphasizes that Eisele’s willingness to take time to relate class topics to the real world — while also respecting the parameters of being a student in today’s pandemic context — helps students as they master difficult topics.

“Active learning, enthusiasm for the subject, clear explanations and a strongly organized course are descriptors that align with Eisele’s approach to teaching,” summarized Callahan. “It is a pleasure to nominate Dr. Eisele for the Dean’s Teaching Showcase.”

Martha Sloan: Tech Tales Emeritus

Professor Emerita Martha Sloan changed the face of both Michigan Tech and engineering education.

Martha Sloan shares her knowledge on Husky Bites, a free, interactive Zoom webinar this Monday, February 28 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.

What are you doing for supper this Monday night 2/28 at 6 ET? Grab a bite with Dean Janet Callahan and Michigan Tech Professor Emerita Martha Sloan, whose impact on people on and off the Michigan Tech campus has been monumental. During Husky Bites, Prof. Sloan will share stories from an earlier time at Michigan Tech, when women in engineering were few and far between.

Joining in during Husky Bites will be Dan Fuhrmann, the Dave House Professor of Computer Engineering and chair of the Department of Applied Computing at Michigan Tech.

“Martha was a faculty member in the Department of Electrical and Computer Engineering when I first came to Michigan Tech in 2008 to take the position of ECE department chair,” notes Fuhrmann. “Shortly thereafter I appointed her as associate chair, a position she held until 2012, just before her retirement after 43 years of service at Michigan Tech.”

A pioneer in many aspects of her career, Sloan is also a legendary mentor who always has time to help anyone who asks. She was the first woman to be hired as a faculty member in the Michigan Tech ECE department, and later became the first woman to serve as chair of the department. Sloan was also the first woman to become the president of the Institute of Electrical and Electronics Engineers (IEEE), the largest professional organization in the world.

Sloan earned all of her three degrees–a BS in Electrical Engineering with great distinction, an MS in Electrical Engineering, and a PhD in Education–at Stanford University. She earned her BSEE in 1961, Phi Beta Kappa and with great distinction, as the only woman among approximately 600 engineering graduates.

Prof. Sloan took home the ASEE Outstanding Young Electrical Engineering Educator Award.

In the 1960s she worked at the Palo Alto Research Laboratory of the Lockheed Missiles and Space Company. She began a PhD program at the Massachusetts Institute of Technology but, feeling isolated there and pregnant with her first child, she did not complete the program. Instead, she moved to Germany, where she taught for two years at the Frankfurt International School. 

“My German was not good enough to be able to work as an engineer, so I taught 7th and 8th grade science, and picked up a MS in secondary education–all  in German–while I was there, too,” Sloan recalls. 

In 1969 Sloan moved to Houghton, Michigan with her husband, Norman Sloan, who had accepted a position as a professor of ornithology, forestry, and wildlife management at Michigan Tech.

As a role model and mentor, Dr. Martha Sloan supports women across campus and around the globe.

“I found myself looking for a job once again and thought I’d go back to teaching,” she says. “At the time there was no need for math or science teachers in the Houghton area. On sheer impulse, I wandered into Michigan Tech’s EE department, just to see if they needed a teacher, since I had a master’s degree. I was hired on the spot to teach Circuits.”

Needing a doctorate for her new job at Michigan Tech, Sloan returned to Stanford to earn a PhD in Education in 1973. Her thesis was on the COSINE Committee, an NSF-funded project to include computer engineering as part of the electrical engineering curriculum. 

Sloan became active in engineering professional societies, serving as treasurer, vice president, and president of the IEEE Computer Society, IEEE, and AAES. She served for nine years on the board of trustees of SWE, the Society of Women Engineers.

To pay tribute to Dr. Martha Sloan’s impressive legacy at Tech and her groundbreaking achievements, ECE alumna Jane Fryman Laird ’68 dedicated a bench at Husky Plaza in Dr. Sloan’s honor. 

Over the years Sloan has been honored with the Frederick Emmons Terman Award by the American Society for Engineering Education (ASEE), the IEEE Centennial Medal, and the IEEE Richard E. Merwin Distinguished Service Award. She received an honorary doctorate from Concordia University, was elected fellow of the Association for Computing Machinery, given the Distinguished Engineering Educator Award of the Society of Women Engineers (SWE), and earned the Michigan Tech Distinguished Service Award, too. (Read Professor Sloan’s complete bio on Wikipedia.)

In 1991 Sloan became a fellow of the IEEE “for contributions to engineering education, leadership in the development of computer engineering education as a discipline, and leadership in extending engineering education to women.”

I’ve liked math and science since grade school, especially physics.

Prof. Sloan, How did you first get into engineering? What sparked your interest?

Prof. Sloan is recognized by the Michigan Tech Alumni Association as an Honorary Michigan Tech Alumna.

The summer before my senior year in high school, I attended a five-week science and technology program at Northwestern University’s National High School Institute, with lectures and labs on all science and engineering programs Northwestern offered, plus field trips to industry in northern Illinois and Indiana. I was particularly enchanted by a unit on AC circuits taught from a book by Kerchner and Corcoran, which I later learned was the standard college text on the subject. By the end of the summer I was the top student in the program—I didn’t know there was a contest—and won a full scholarship to Northwestern. But I didn’t go to Northwestern; I went to Stanford, which I chose because the campus was so beautiful. This was before Stanford was as highly ranked as it is today (it was near the bottom of the top 20).

I intended to major in physics, but then, in the  summer just before my freshman year, a letter arrived from Stanford advising me that if I had any thought of possibly majoring in engineering, I should start in engineering because transferring out was easy but transferring in might delay my graduation. So I chose electrical engineering, based on liking AC circuits.

Hometown and family?

I was born in Aurora, Illinois to an obstetrician and stay-at-home mom. They had both majored in chemistry in college. My brother became a math professor and assistant chair of the math department at the University of Illinois.

Three of Prof. Sloan’s adorable grandkids!

My daughter is a law professor at Chicago Kent. Her daughter (my granddaughter) earned an MS in Public Health and conducts research in Boston on comorbidities, when a patient has two or more diseases or medical conditions the same time. She has boy-girl twins who are now both studying medicine at different medical schools in Chicago. In addition, my great granddaughter’s longtime boyfriend is studying at a third Chicago medical school—so the family has Chicago medical schools almost covered! 

My son graduated from the US Naval Academy, spent 20 years in the Marines, and is now working on safety aspects of autonomous vehicles for General Motors. He and his wife, also a USNA graduate, have three young children.

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

I have two springer spaniels. I spend my spare time reading–and doing some writing, too. I’ve taken two classes on writing memoirs in the past year.

Prof. Dan Fuhrmann’s research focus: signal processing.

Prof. Furhmann, how did you first get into engineering and computing? What sparked your interest?

I was good at math and science in junior high and high school, so it just seemed like a natural path.

Hometown, family?

Born in Bartlesville, Oklahoma and later moved to Tulsa, Oklahoma. I am the youngest of four children. Currently married 26 years with three grown children in a blended family.

What do you like to do in your spare time?

Jamming on the deck!

I’ve played piano semi-professionally my entire adult life, including jazz, pop, rock, and salsa. I enjoy both downhill and cross-country skiing. I try to take advantage of the Copper Country winters!
