Excellence in Student Publishing

Published October 19, 2022

Global map with readership numbers marked at various locations.

This week, October 17–21, 2022, the Graduate School and the Van Pelt and Opie Library celebrate International Open Access Week. The event is organized by the Scholarly Publishing and Academic Resources Coalition (SPARC).

This year, we’re marking Open Access Week by recognizing the 10 years of master’s theses, doctoral dissertations and master’s reports (ETDRs) that are freely available to the world through Digital Commons @ Michigan Tech, the University’s institutional repository. This collection of works is comprehensive back to 2012, and some are nearly a decade older. With Digital Commons, we’re provided with usage statistics that show activity on the platform and across the web. Throughout the week, we’ll share stories and insights informed by these statistics that speak to how publishing Open Access has benefitted Michigan Tech students. In the meantime, take a moment to check out the collection of ETDRs on Digital Commons @ Michigan Tech.

One great feature of Digital Commons @ Michigan Tech is its shareable readership dashboard. This dashboard displays statistics related to how users are interacting with content on the repository. For example, users have downloaded Michigan Tech master’s theses, master’s reports and dissertations over 1.5 million times from 227 different countries.

Yixin Liu: Sensing Smells

Published October 13, 2022

By

Dogs can potentially detect human diseases—including cancer and diabetes—from smell alone. At Michigan Tech, Yixin Liu, an assistant professor Chemical Engineering, develops “electronic noses” that can rival even the best dog nose.

Yixin Liu shares her knowledge on Husky Bites, a free, interactive webinar this Monday, 10/17 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.

What are you doing for supper this Monday night 10/17 at 6 ET? Grab a bite with Yixin Liu, assistant professor of Chemical Engineering at Michigan Tech. Joining in will be Riley Smith, the first undergraduate student researcher to join Prof. Liu’s Smart Chemical and Biological Sensing Laboratory at Michigan Tech. Liu develops chemical sensors and biosensors, electronic noses/tongues and sensor data analytics.

During Husky Bites, Prof. Liu will share how she goes about developing an “electronic nose” using an array of gas sensors and a data-analyzing algorithm. The result is a device that can mimic our biological olfactory system, able to sense smells in various applications, such as gas pollutants and breath analysis for medical diagnosis.

The ideal electronic nose is capable of sensing far better than even the best human nose ( more like a dog nose). “Dogs have a superior sense of smell. With training, dogs can sniff out bombs and drugs, pursue suspects, search and rescue lives, and potentially detect human diseases—including cancer and diabetes—from smell alone,” Liu says.

Prof. Liu uses nanofibers (seen here on the nanoscale) as sensing material to create electrochemical sensors. Coupled with machine learning techniques, the device turns into a smart nose with a number of superpowers.

Liu joined the faculty of the Department of Chemical Engineering as an assistant professor in 2020. She earned her PhD in Chemical Engineering from the University of Connecticut and her bachelor’s degree in Polymer Material Science and Engineering from Zhejiang University in China.

“Riley was the first undergraduate student to join my lab at Michigan Tech,” says Liu. He reached out to me last year after my brief presentation to the Michigan Tech AIChE student group, indicating his interest in undergraduate research.

“Riley is highly motivated and proactive,” adds Liu. “After training on the lab’s electrospinning machine for nanofiber fabrication, he took the initiative to come up with a detailed operation manual with pictures. Riley’s manual has helped many students in my lab to learn how to use the machine.”

“Once I heard Dr. Liu’s AIChE presentation, I reached out to learn more,” Smith adds. “I started working with Dr. Liu, and now I work along with many more students who have joined the team as the lab continues to grow.”

Liu’s interdisciplinary lab combines advanced nanostructured materials, device design, and data-driven approaches to develop high performance chemical and biological sensing technologies. Liu and her collaborators already have 4 US patents granted, with another six patent applications pending.

At Michigan Tech Liu and her research group work together to develop electrochemical sensors coupled with machine learning techniques. “The knowledge gained from our research leads us to other new low-cost biosensing devices and manufacturing processes,” says Liu.

Recently she was awarded an Engineering Research Initiation (ERI) grant from the National Science Foundation to develop a nanocomposite sensor for the simultaneous detection of glucose and cortisol.

“People with diabetes are 2-3 times more likely to have depression,” note Liu. “In addition, symptoms of depression and anxiety are often associated with elevated cortisol (the ‘stress hormone’) which can lead to the onset of type 2 diabetes. If we could monitor both glucose and cortisol levels in a cost-effective and effortless way, that could help manage both diabetes and stress—it could also prevent pre-diabetes from progressing to full-blown type 2 diabetes,” Liu says.

“One of my long-term research goals is to develop a low-cost, easy-to-manufacture and high-performance biosensing technology based on e-MIPS—electropolymerized Moleculary Imprinted Polymers. I think e-MIPS could become an important platform for detecting biomarkers in human biofluids,” she says. “This would allow for ‘decentralized diagnostics’—rapid medical testing that can take place outside a hospital setting. Testing could be done at a satellite lab, doctor’s office, or even at home.”

Developing a reliable sensor that can detect polluting gas in real time, at an early stage, even in aggressively high heat, is another one of Liu’s research projects.

“Monitoring and control of combustion-related gases, including oxygen, carbon monoxide and hydrocarbons, are a top priority in many industries,” she says. “To be effective, though, sensors must be operate at 800~1000 ◦C. Right now, very few sensors have been able to detect gases above 600 ◦C, even in a laboratory setting.”

Once achieved, though, Liu says real-time, high-heat monitoring could save energy and help reduce pollution emissions.

Prof. Liu, how did you first get into engineering? What sparked your interest?

My father is a mechanical engineer, and I have always watched him fix things and build new things at home since I was very young. I liked math, hands-on experiments, and exploring new technologies when I was in high school. It was quite natural for me to choose an engineering major when I went to university.

Hometown, family?

I grew up in Sichuan, China (hometown of spicy foods and the panda.) I was the only child of my parents (no siblings). My husband and I have a 4-year-old son.

What do you like to do in your spare time?

I have liked painting for years, and still do acrylic paintings in my spare time. I started to learn piano 5 years ago, and now I’m still learning, practicing, and having fun.

“Riley’s manual has helped many students in my lab to learn how to use the electrospinning machine,” says Prof. Liu.

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

I first got interested after having a conversation with my chemistry teacher in high school. I thought that engineering would be a fitting job—I knew I wanted to do something that required some type of problem-solving. After talking with a family friend who works in chemical engineering, my interest solidified. I finished my associate degree in science at a community college and started looking into four-year technological universities.

Hometown, family?

I am from Kalamazoo, Michigan. My family consists of my mom, a younger brother who is in his junior year of high school, an older sister who is getting married in October, and my dad who works in consulting.

What do you like to do in your spare time?

I like to spend a lot of time outdoors, whether hiking, kayaking, or hammocking. I have a small poodle mix who accompanies me on many of my outdoor ventures. I also like to work with my hands, on either woodworking projects or refinishing furniture.

Sustainable Foam: Coming Soon to a Cushion Near You

Published May 27, 2022

By

Chemical engineering major Lauren Spahn presented her research at the Michigan Tech Undergraduate Research Symposium. Her lignin project was supported by Portage Health Foundation, the DeVlieg Foundation, and Michigan Tech’s Pavlis Honors College.

Most polyurethane foam, found in cushions, couches, mattress, insulation, shoes, and more, is made from petroleum. What if it could be environmentally-friendly, sustainable, and made from renewable biomass? It’s entirely possible, thanks to the work of chemical engineering student Lauren Spahn and her fellow researchers at Michigan Tech. It all happens in the Biofuels & Bio-based Products Lab at Michigan Tech, where researchers put plants—and their lignin—to good use. The lab is directed by Dr. Rebecca Ong, an associate professor of chemical engineering.

Q&A with Lauren Spahn

Please tell us a little about your work in the lab.

Our goal in working with Dr. Ong is to develop sustainable industries using renewable lignocellulosic biomass⁠—the material derived from plant cell walls. There are five of us working on Dr. Ong’s team. We develop novel co-products from the side streams of biofuel production, and pulp and paper production. We’re trying to make good use of the leftover materials.

Lignocellulose, aka biomass, is the dry matter of plants. Energy crops like this Elephant Grass, are grown as a raw material for the production of biofuels.

What kind of research are you doing?

My particular research project involves plant-based polyurethane foams. Unlike conventional poly foams, bio-based foams are generated from lignin, a renewable material. Lignin is like a glue that holds wood fibers together. It has the potential to replace petroleum-derived polymers in many applications. In the lab, we purify the lignin from something called “black liquor”⁠. It’s not what sounds like. Black liquor is a by-product from the kraft process when pulpwood is made into paper. Lignin is collected by forcing dissolved lignin to precipitate or fall out of the solution (this is the opposite of the process of dissolving, which brings a solid into solution). By adjusting the functional properties of lignin during the precipitation process, we hope to be able to tailor the characteristics of resulting foams. It’s called functionalization.

Typically in the lab process, functionalization occurs on lignin that has already been purified. What we hope to do is integrate functionalization into the purification process, to reduce energy and raw material inputs, and improve the economics and sustainability of the process, too.

Purified lignin, used to make bio-foam. The resulting foam will likely be light or dark brown in color because of the color of the lignin. It would probably be used in applications where color does not matter (such as the interior of cushions/equipment).

How did you get started in undergraduate research?

I came to Michigan Tech knowing I wanted to get involved in research. As a first-year student, I was accepted into the Undergraduate Research Internship Program (URSIP), through the Pavlis Honors College here at Tech. Through this program I received funding, mentorship, and guidance as I looked to identify a research mentor.

How did you find Dr. Ong, or how did she find you?

I wanted to work with Dr. Ong because I found the work in her lab to be very interesting and relevant to the world we live in, in terms of sustainability. She was more than willing to welcome me into the lab and assist me in my research when I needed it. I am very thankful for all her help and guidance.

Lignin is like a glue that holds wood fibers together, giving trees their shape and stability, and making them resistant to wind and pests. Pictured above, a biofuel plantation in Oregon.

What is the most challenging and difficult part of the work and the experience?

Not everything always goes according to plan. Achieving the desired result often takes many iterations, adjustments, and even restructuring the experiment itself. After a while, it can even become discouraging.

What do you do when you get discouraged? How do you persevere?

I start thinking about my goals. I enjoy my research—it’s fun! Once I remind myself why I like it, I am able to get back to work.

Lignin at the nanoscale, imaged with transmission electron microscopy (TEM). Raisa Carmen Andeme Ela, a PhD candidate working in Dr. Ong’s lab, generated this image to examine the fundamental mechanisms driving lignin precipitation.

What do you enjoy most about research?

I enjoy being able to run experiments in the lab that directly lead to new designs, processes, or products in the world around me. It’s wonderful to have the opportunity to think up new product ideas, then go through the steps needed to implement them in the real world.

What are your career goals and plans?

I plan to work in R&D for industry. I am very passionate about research—I want to continue participating in research in my professional career.

Why did you choose engineering as your major?

The field is so large. Chemical engineers can work in industry in numerous areas. I liked the wide variety of work that I could enter into as a career.

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

Published April 7, 2022

By

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.”

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.

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.”

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!”

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.”

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.

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.

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.

MTU Students, Faculty and Staff: sign up for LEED Green Associate exam prep training here.

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.

Dean’s Teaching Showcase: Timothy Eisele

Published February 28, 2022

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.”
