Assistant Professors Kōnane Bay and Ankur Gupta from ��ý�Ļ��Ʒ’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 ��ý�Ļ��Ʒ’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.

��ý�Ļ��Ʒ 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 ��ý�Ļ��Ʒ and the 3M Company—especially Professor Ryan Hayward, Professor Tim White, Hyunki Kim, Aaron Hedegaard, Jason Clapper and Eric Nelson.”

Paula Pranda, a ��ý�Ļ��Ʒ 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 ��ý�Ļ��Ʒ’s Young Scholars Summer Research Program (YSSRP), Kate Lamb was inspired to change her path, transferring from community college to ��ý�Ļ��Ʒ’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 ��ý�Ļ��Ʒ 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 ��ý�Ļ��Ʒ—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 ��ý�Ļ��Ʒ. 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 ��ý�Ļ��Ʒ?

The graduate students who mentored me, and Dr. (Rob) Davis and Dr. (Tim) Whitehead took the time to discuss what studying at ��ý�Ļ��Ʒ 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.

Laurel Hind honored with CAREER Award for advancing immune response research Susan Glairon Fri, 01/17/2025 - 15:42

Laurel Hind is studying the signals that regulate the immune system and contribute to disease, supported by a major grant awarded to promising early-career faculty.

Hind, an assistant professor in the Department of Chemical and Biological Engineering at the University of Colorado Boulder, has received a prestigious National Science Foundation CAREER Award. This highly competitive program supports faculty with potential to become leaders in research and education.

The $646,000, five-year grant will support Hind's research on how the tissue environment directs the innate immune response. It will also fund outreach efforts to improve scientific literacy in immunology through a new program, “Immunology in our Everyday Lives."

“I am grateful for this award because it recognizes and builds on the work my students have done to understand how the tissue environment regulates innate immunity while also opening a completely new research area for my lab, which is very exciting," Hind said. "I am happy that the field recognizes the importance of understanding how physical cues regulate cell function.”

The innate immune response acts as the body's first line of defense against harmful invaders like bacteria or viruses, injuries and disease, and plays a critical role in maintaining health. However, an imbalance in the immune system can lead to inappropriate responses which are increasingly linked to diseases such as cancer, cardiovascular disease, chronic infections and fibrosis, and aging, Hind said. Understanding the signals that control this response and how they become dysregulated in disease could help develop new treatments.

The award will support Hind and her team in exploring how physical changes in tissues affect immune function and contribute to worsened disease outcomes as diseases affected by immune system problems often involve changes in the physical properties of tissues. For example, tissues become stiffer in cancer and fibrotic diseases, but lose structure during the aging process. While the chemical signals that influence the immune system in these processes are well studied, how the physical properties of tissues impact immunity is not yet fully understood.

Using novel biomaterials in an innovative “inflammation-on-a-chip” device, Hind and her team will examine how properties such as stiffness, elasticity and the dynamics of tissue stiffening affect innate immune cell function. Importantly, it will identify the genes and proteins that drive these changes, providing targets for future therapeutic development.

The award will also support the development of a curriculum to improve scientific literacy in immunology to encourage public health initiatives through community-engaged outreach. This curriculum will use games and hands-on activities to explain how antibiotics and antibodies work and demonstrate the importance of herd immunity. It will also help retain and recruit women and historically excluded students in science and engineering by involving them in research and curriculum development.

“Public health initiatives like broad participation in vaccination and reducing the overuse of antibiotics are so important for the health of our communities, yet many people don’t understand why, which can lead to resistance," Hind said. "I am excited to share our knowledge in an accessible way with students and families in our community.”

Assistant Professor Laurel Hind has received a $646,000 NSF CAREER Award to study immune system regulation and disease, while also promoting scientific literacy in immunology through a new outreach program.

Polymer thin films can extend the lifespan of everyday products, such as food packaging for preserving freshness and protective coatings for electronics. Advancing their design to be even thinner and more durable could expand their applications further.

Kōnane Bay, an assistant professor based in the University of Colorado’s Department of Chemical and Biological Engineering, recently received a prestigious CAREER Award, a $675,000, five-year grant from the National Science Foundation. The funding will advance her work in polymer characterization and support the development of high school and summer program curricula that integrate materials science and engineering lessons with traditional Indigenous knowledge.

“It feels great to be recognized by the polymer community for both the scientific and outreach work that we are doing,” Bay said.

The award will support Bay and her team at the Huli Materials Lab in investigating how the mechanical properties of polymer films evolve as their thickness is reduced to less than 100 nanometers—about a thousand times thinner than a human hair or cling wrap. Many industrial applications depend on the mechanical performance and stability of these films. The difficulty, Bay said, lies in the fact that when polymer materials are processed into thinner films, their mechanical strength changes in ways that are not yet fully understood.

Assistant Professor Kōnane Bay oversees a graduate student working on an instrument in the Huli Lab.

Using a custom-built instrument, researchers in the Huli Lab will study how variables like thickness, temperature and surface interactions affect the strength of these films. The findings will provide valuable insights for designing more reliable adhesives, coatings and membranes while reducing material costs, energy use and environmental waste.

The project will fund a PhD student for five years to study the mechanics of ultrathin polymer films.

In addition to supporting research, the funding will enable the development of high school and summer program curricula that integrate materials science and engineering with traditional Indigenous knowledge. Growing up in Hawaiʻi, Bay draws from her heritage to shape this initiative, which aims to increase STEM recruitment and retention among women and historically excluded students, particularly Native Hawaiians, through curriculum development, outreach and mentoring to inspire the next generation of diverse STEM leaders.

“The curriculum will be designed to inspire high school students across Colorado and Hawaiʻi to explore and pursue advanced degrees and careers in STEM disciplines,” Bay said.
