In an impressive comeback, ��ɫ��Ƶ students won the American Institute of Chemical Engineers Chem-E-Car competition at the Rocky Mountain regional. The event was held in Bozeman, Montana from April 11-12.

��ɫ��Ƶ's Chem-E-Club club dissolved during the COVID-19 pandemic but was revived in 2021 by five students, said Claire Ely, a senior majoring in chemical engineering and one of the students who helped bring it back. Since then, it has grown to a team of about 20 members.

"This year's success is unbelievably exciting," Ely said. "The four seniors in the club feel like proud parents."

One of their cars, "Don't Zinc and Drive," took first place in both the car competition and the poster presentation; the team's second car, "Ralphie," placed third in the car competition. The first-place win secured ��ɫ��Ƶ a spot at the national AIChE competition in Boston this November.

The competition's goal is to design a shoebox-sized car powered by chemical reactions— such as a battery or an internal combustion engine — that

stops at a specified distance using a time-dependent chemical reaction. The target distance is revealed just before the competition, and the team whose car stops closest to that distance wins.

Throughout the year, ��ɫ��Ƶ students designed, built and tested their car ideas in the chemical engineering undergraduate teaching lab, supported by Assistant Teaching Professor Ehsan Keyvani.

"Don't Zinc and Drive" is powered by zinc-air batteries and stopped using an acid-base neutralization. "Ralphie," is powered by a hydrogen fuel cell and stopped using an enzyme-catalyzed digestion.

"The club is a fun and low-stakes way to reinforce engineering principles hands-on, regardless of experience," Ely said. "Students, not just chemical engineering majors, develop a ton of skills, including electronics, mechanical design CAD prototyping, reaction engineering and experimental design.”

"We look forward to what Chem-E-Car brings next!," she said.

The club is supported by funding from the Department of Chemical and Biological Engineering and has received Engineering Excellence Fund support in the past.

Students interested in joining ��ɫ��Ƶ's Chem-E-Club can send an email to chemecar@colorado.edu. The club can also be followed on Instagram @boulderchemecar.

Annette Thompson, a chemical engineering PhD student, has received a 2025 National Science Foundation Graduate Research Fellowship, a prestigious award that recognizes and supports outstanding students in a wide variety of science-related disciplines. Thompson is co-advised by Associate Professor Jerome Fox and Professor Michael Shirts.

This year, the National Science Foundation awarded Graduate Research Fellowships to 12 ��ɫ��Ƶ students, including five from the College of Engineering and Applied Science. Due to federal budget cuts, the program was reduced by 50 percent, with only 1,000 fellowships awarded nationwide compared to 2,000 last year.

Fellows receive a three-year annual stipend of $37,000 and full coverage of tuition, fees and insurance, along with opportunities for international research and professional development that span five years.

What is your research focused on?

My research focuses on better understanding and redesigning the molecular “assembly lines” that cells use to make chemical building blocks, especially fatty acids. These natural systems rely on helper proteins to guide molecules through a series of enzymatic steps, but how these enzymes selectively interact with their partners is still not well understood.

I use computer-based tools—like simulations that predict how molecules move and interact over time, and models that estimate how changes in enzyme levels and behavior impact final yield—to study these systems and identify engineering targets for controlling product outcomes. By combining computational methods with experimental collaboration, my work aims to help create new biotechnologies that can produce a wider range of useful chemicals more efficiently than nature can on its own.

What are potential applications of your work?

My research could lead to more sustainable ways to make everyday products like medicines and fuels, without relying on petroleum-based processes. By making enzyme systems more precise and efficient, we can lower costs and create cleaner, greener manufacturing processes.

What does receiving this award mean to you?

Receiving this award is a huge honor. The support will allow me the flexibility to expand my research into new biosynthetic pathways and organisms, and to develop faster and better tools for characterizing new systems. I am deeply grateful to my advisors, Dr. Jerome Fox and Dr. Michael Shirts, whose support and expertise have been instrumental in shaping this work and making these collaborations possible.

Assistant Professors Kōnane Bay and Ankur Gupta from ��ɫ��Ƶ’s Department of Chemical and Biological Engineering have been honored with the 2025 Air Force Office of Scientific Research (AFOSR) Young Investigator Program Award.

Each received a $450,000, three-year grant to advance research relevant to the Air Force. The program, offered by the Air Force Research Laboratory, supports early-career scientists and engineers with “exceptional ability and promise for conducting basic research,” according to the AFOSR.

“This is among the most prestigious awards given to junior faculty, and to have both Ankur and Kōnane receive it in the same year is a remarkable testimony to their impressive achievements and very high potential for making future advances,” said Professor Ryan Hayward, chair of the department.

Kōnane Bay, self-healing, innovative materials

Bay says the next generation of polymer materials—materials with long chains of molecules like plastics, rubber and proteins—will need advanced features, such as the ability to repair themselves. While engineering synthetic polymers with these properties is challenging, biofilm-forming bacteria are promising as they use internal material factories to produce polymers on demand to survive changes in the surroundings.

“I am grateful to receive this award which will allow our lab to harness nature to create novel engineered living materials,” Bay said.

The award will support Bay and her team at the Huli Materials Lab in using biofilm-forming bacteria to develop new polymeric materials. The project combines 3D printing with bacteria’s natural movement to control the mechanical properties of biofilm-based synthetic polymers. The findings could lead to self-healing materials that can change shape, with applications in aerospace, soft robotics, and protective coatings.

Bay recently also received a prestigious CAREER Award, a $675,000, five-year grant from the National Science Foundation. The funding will advance her work in characterization of polymer thin film.

Ankur Gupta, more precise chemical sensors

Imagine being able to organize tiny particles as small as one-twentieth the thickness of a human hair.

Gupta’s research aims to do just that. He and his team in the Laboratory of Interfaces, Flow and Electrokinetics (LIFE) study how these tiny particles form patterns through chemical reactions and diffusion. The researchers aim to control this process to develop materials that detect microscopic changes in the air, paving the way for advanced chemical sensors that identify subtle chemical shifts and improve safety.

“It’s an honor for us to receive this award, especially given its prestige and selectivity,” Gupta said. “This recognition is a testament to the hard work of my current and past group members, and I am grateful for the opportunity to work with them.”

The $450,000 three-year grant will support a graduate student and cover travel expenses.

In 2024, Gupta was honored with the Johannes Lyklema Early Career Award in electrokinetics. He was also selected for the prestigious “35 Under 35” award from the American Institute of Chemical Engineers in 2023.

That same year Gupta also received a $517,000, five-year National Science Foundation CAREER Award, to study how ions move through porous materials. His research will help design improved porous materials for more efficient desalination and renewable energy storage.

Paula Pranda, a chemical and biological engineering PhD student, earned the top student honor at the Adhesion Society meeting for her research on aligned Liquid Crystal Elastomer (LCE) adhesives. The society’s annual meeting was held Feb. 16-19 in New Orleans.

Pranda received the Alan Gent Distinguished Student Paper Award, recognizing the most distinguished paper among top students who had previously won the Peebles Award for outstanding graduate research in adhesion science. The Adhesion Society advances adhesion science, promotes education and honors achievements in the field.

“Winning this award is an incredible honor,” said Pranda, who works with ��ɫ��Ƶ’s Hayward Research Group and Responsive and Programmable Materials Group. “It’s validating as a young researcher and exciting because it shows that the scientific community values our work.”

LCEs are soft, stretchy materials with a unique structure formed by liquid crystal monomers, which have a long oval shape. Using specific processing methods, these monomers can be aligned in one direction. When stretched along this alignment, the polymer behaves like a classic elastomer, meaning it can stretch and return to its original shape. However, when stretched perpendicular to the alignment, it becomes much softer and stretchier as energy is dissipated into rotating the monomers.

��ɫ��Ƶ and the 3M Company research team leveraged this property to develop pressure-sensitive adhesives (PSAs). Their findings showed that the peel strength depends on monomer orientation—adhesives are harder to remove when monomers are perpendicular to the peeling direction. By using a laser to pattern different alignments, the team was able to create adhesives with regions of varying peel force.

“This award is a testament to the community's excitement about Paula’s findings on how adhesion can be tailored using LCEs, and her outstanding presentation,” said Professor Ryan Hayward, the director of the Hayward Research Group and the department chair. "Tim (White) and I are very proud of Paula—it has been a true pleasure collaborating with her on this project.”

Directional control of adhesion offers many potential applications, Pranda said. In diabetic ports, patterned LCE adhesives can ensure strong skin adhesion while allowing painless removal in a specific direction. Similarly, for screen protectors, aligning monomers perpendicular to common failure points can prevent edge peeling, while parallel alignment allows for easy removal when needed.

“This recognition means so much,” Pranda said. “I couldn’t have achieved it without the support of my amazing mentors and collaborators at ��ɫ��Ƶ and the 3M Company—especially Professor Ryan Hayward, Professor Tim White, Hyunki Kim, Aaron Hedegaard, Jason Clapper and Eric Nelson.”

Paula Pranda, a ��ɫ��Ƶ PhD student, won the top student award at the Adhesion Society's annual meeting for her research on Liquid Crystal Elastomer (LCE) adhesives. Her work has potential applications in medical devices and screen protectors among others.

Kate Lamb stands between YSSRP participants Paloma Suárez Davila (left), who attends Colorado Mesa University and Runa Kersten-Guiler, who attends the University of New Hampshire.

After a summer in ��ɫ��Ƶ’s Young Scholars Summer Research Program (YSSRP), Kate Lamb was inspired to change her path, transferring from community college to ��ɫ��Ƶ’s Department of Chemical and Biological Engineering as a biological engineering major.

YSSRP’s nine-week program prepares undergraduate students for research careers and graduate study through hands-on experience and professional development. Open to all qualified applicants, the program strongly encourages participation from students underrepresented in engineering and those from schools with limited research opportunities.

You started classes at ��ɫ��Ƶ in January. How’s it going so far?

It’s good! I took chemistry, physics and biology at Arapahoe Community College (ACC), so I am well-prepared for upper-division coursework.

How did you learn about this program?

After reviewing my classes and interests, my career counselor at ACC thought I might like engineering and recommended the YSSRP. I feel really fortunate that I was accepted to the program.

What were your academic plans before participating in the YSSRP?

I was planning to major in math, though I wasn’t sure where I wanted to study. I really love math and biology and have an interest in medicine, but I wasn’t sure how they connected. That’s what drew me to biological engineering at ��ɫ��Ƶ—it brings everything together.

What did you enjoy about your YSSRP research project?

My project introduced me to synthetic biology, a field that combines biology and engineering, which I find fascinating. It involves designing and building new biological systems or modifying cells to give them new traits or to produce useful products.

I worked with two PhD students to optimize a biosensor—a protein that detects biological substances, and converts that detection into a measurable signal. Biosensors have the potential to be used as non-invasive medical diagnostic tools and even as therapeutic devices. Our goal was to improve T7 RNA polymerase biosensors, and after extensive troubleshooting, we finally got results that worked. That moment was incredibly gratifying and showed me how much persistence goes into research. Our results formed the basis of a paper that was accepted for publication.

How did participating in the YSSRP influence you to switch from math to engineering?

It opened a door to a way that I could combine all my different interests. Previously I thought I had to choose one specific discipline like biology or math or chemistry. After I started working in the lab, I began learning about the degrees offered at ��ɫ��Ƶ. Now I'm taking differential equations and organic chemistry—different areas of study that I didn’t know could fit together in one degree program.

Why did you decide to attend ��ɫ��Ƶ?

The graduate students who mentored me, and Dr. (Rob) Davis and Dr. (Tim) Whitehead took the time to discuss what studying at ��ɫ��Ƶ would be like and how the degree programs are structured. The opportunity to continue doing research was a big part of my decision to attend CU.

What was your favorite part of participating in the YSSRP?

The research was exciting, but there were other elements of the program that I really enjoyed. We had lunches with professors and weekly talks on different topics such as working in industry, intellectual property and graduate school opportunities. It made me think how cool it would be to be sitting in one of those professor’s classes.

As a group we had regular outings, for example, we went hiking, whitewater rafting and bowling. I made a couple of close friends in the program who worked in labs down the hall from me, and we had a really fun time exploring Boulder together. I only have good things to say about the program and its impact on me.

What are your plans for the future?

I’d like to stay in research, and graduate school seems like a strong possibility. I have ideas that I want to explore, and I hope to contribute meaningfully to developing diagnostics and therapeutics that will improve patient care.
