My Story: Katherine Baker, MTUengineer

I’m originally from Austin, Texas and grew up in that area, then eventually moved up to McAlester, Oklahoma. I decided on Michigan Tech because of its strong engineering program. I also wanted to experience living in a new area and see some snow, which I’ve definitely been able to do. I started out in the general engineering program and settled on chemical engineering towards the end of my first year because I enjoy math and chemistry and really like learning how different processes work.

“My time at Tech has shaped my life in incredible ways.”

I attended the fall career fair last month and had a great experience, both personally and professionally. I learned about companies I am interested in and connected with recruiters, and many are Tech alumni. I ended up accepting a hybrid co-op offer from Kimberly-Clark. I’ll work onsite at their facility in Neenah, Wisconsin over the summer, then part-time remotely from campus next year.

In August I completed an eight-month co-op with Billerud at their paper mill in nearby Iron Mountain, Michigan. Most of my projects revolved around chemical savings and energy optimization. I worked in a process engineering role on their pulp mill team, and was able to learn from both engineers and operators. I learned a ton about trial planning, technical communication, and the paper industry.

I have a few other jobs on campus. I work as an RA in the dorms at Michigan Tech. I also work as a peer mentor in the Department of Chemical Engineering. Both roles give me opportunities to connect with new students and help them navigate their first few years at Tech, which is really fulfilling for me. I also serve as the treasurer of the Chemical Engineering Student Advisory Board, and flute section leader in the Huskies Pep Band.

I’m an active member of the Society of Women Engineers (SWE). It’s given me so many opportunities to connect with other women on campus and figure out my career path. I recently completed the SWE 2022-2023 Collegiate Leadership Institute, a professional development program. I attended seminars put on by successful women in industry, met with a professional mentor, and grew in my leadership skills.

This month I will be attending the national SWE conference, WE23, in Los Angeles with other members of the Michigan Tech SWE section. I’m super excited for all the opportunities at WE23—to hear from more women in engineering and broaden my professional network.

My time at Tech has shaped my life in incredible ways. I’m so grateful for the strong, tight-knit community up here and feel super supported in my goals by both faculty and other students. As an RA and peer mentor, I try to give back to the community by supporting incoming students, just like I was supported my first few years. Being in the engineering program has given me so many opportunities to grow professionally.

After college, I plan to work as a process engineer, hopefully at a plant where I can really get hands-on with my projects. I’m not yet sure which industry I want to be in long-term, but I’ve learned about so many different ones through my co-op and networking with company recruiters. I’m excited to continue learning and choose one that turns out to be the best fit for me.

Advice to incoming students, from Lauren Spahn

My advice to incoming students? Chemical engineering classes can be challenging and there might be points when you think you’re not cut out for it and should choose an easier major (I know I’ve had those moments). Be confident in yourself and learn as much as you can. Keep your head up and try to develop a support system early on with fellow students.

Sustainable Foam: Coming Soon to a Cushion Near You

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 engineer Lauren Spahn ’22 (now an alumna) 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. 

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.

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. 

Editor’s note: Lauren graduated with a BS in Chemical Engineering in April 2022, and started work at Hemlock Semiconductor in Saginaw, Michigan soon after.
