Mark Adams '93
Mark Adams, ’93 Polymer Program

Mark Adams received his Ph.D. in Polymer Science from the University of Connecticut in 1993. After an 11-year tenure with Dow Chemical, Adams joined Henry Company in various vice president and senior vice president roles. Following his tenure at Henry Company, Adams joined Associated Materials, acting in senior vice president and later executive vice president positions. Since May of 2023, Adams serves as the Chief Operating Officer of HASA Inc., a large water treatment company based in southern California.

IMS News reached out to Adams with five questions about his breadth of professional experience since obtaining his Ph.D., and how his time at UConn shaped it. Adams shows us that with grit, passion, and a strong support system, career growth occurs naturally.

Why did you choose to pursue your Ph.D. in polymer science at UConn?  

My plan was to go to medical school after completing a B.S. in Chemistry from UConn. While working on my B.S., I took Physical Chemistry with Professor Andrew Garton. One day about halfway through the semester, he approached me after class and asked about what I was going to do after undergrad. I told him I was planning to go to medical school. He asked if I had ever considered grad school.

He went on to talk about an opportunity to go to the Institute of Materials Science for a Ph.D. in Polymer Science, working with him under a grant from NASA. Curious about the opportunity, I went to visit him at IMS, and the rest is history. I changed direction and worked to earn my Ph.D. on a research project for NASA, studying the degradation of polymeric spacecraft materials in the low earth orbit.

Who were some of the people who helped or inspired you most during your time at UConn, and how did their influence carry over into your professional career?

Obviously, Professor Garton had a huge impact on my academic career. He was incredibly energetic and excited about his research, which was infectious in his research group. When he passed away suddenly, prior to me completing my thesis, I was shocked and somewhat lost. My mentor in research was gone, and I was uncertain about the future and the choices I made. Fortunately, Sam Huang took me on to complete my degree.

Dr. Garton and other faculty at IMS taught me the importance of first principles and how to do research, but Dr. Garton is responsible for teaching me how to apply learning.  How to identify a problem, develop root cause, research/develop technology needed, and implement technology solutions. He also helped me develop continuous improvement skills that have become the backbone of my career. Advanced research is interesting and fun but, using that to develop products and solutions is exciting.

A lot of your professional experience is more on the business side rather than in a lab or research setting. How did your Ph.D. and heavy scientific background impact your trajectory for success in so many executive-level corporate roles? 

The first few roles early in my career were focused on technology and product development, which heavily leveraged my Ph.D. Successfully translating these efforts into value-creating opportunities required a complex voice of the customer requirements, which was only obtained and validated through observation and communication with end users. It’s at this interface where my unique skills started to develop, and when my career started taking turns from R&D leadership to new business development, sales, commercial leadership, and operations leadership. I have been fortunate to work with exceptional executive leaders that continually challenged and developed me, which has produced a myriad of different and challenging roles. This would not have been possible without the solid foundation I received from IMS and UConn.

What advice do you have for current polymer science students who may be unsure of their career paths? 

Figure out your “internal” job description as early as possible. In other words, determine what you like to do most in combination with the skills and experience you have developed. When you figure out what your internal job description is, and you find a role that matches, you will experience dramatically accelerated growth. In my case, that was away from pure and applied research, and more focused on deploying all kinds of chemistry and engineering to develop solutions that rapidly grow businesses. Once you figure that out, job opportunities come faster than will be comfortable.

What are you most proud of having accomplished so far in your current position, and what do you most hope to accomplish going forward?

I am currently the Chief Operations Officer at a specialty chemical company specializing in water treatment. This role is truly the culmination of all my years of experience in multiple functions and companies. I am responsible for Operations at 12 sites, Engineering, Product/Process Development, EH&S, Continuous Improvement, Quality, and Transportation.

My biggest accomplishment so far with this company has been successfully restructuring and realigning our engineering group into a segmented portfolio management approach. We had way too many projects, worked on all of them at once, with too few resources, and no prioritization. Everything was delayed and above budget. Now, we are executing on time and on budget across the board on a full spectrum of projects from large new site design-builds, down to site specific capex projects.

My biggest challenge is developing and implementing automation technology in our packaging plants. We still require too much manual labor in an environment that is ergonomically challenging. Also, working with hazardous and corrosive materials poses unique challenges to metals and circuitry, so we needed to develop materials, machines, and now robots that reliably operate in challenging environments with hazardous chemicals. I guess it’s kind of like my Ph.D. work that analyzed polymers in low earth orbit, also a challenging and unforgiving environment.

IMS News thanks Mark Adams very much for his willingness to share his unique journey. We are excited to see where he takes HASA next.

Xiaoting Xue (left) and Xincheng Zhang of the Yi Zhang Group
Xiaoting Xue (l) and Xincheng Zhang of the Yi Zhang group are first co-authors on research recently published by Nature Communications

The Yi Zhang research group paper, “Liquid-based encapsulation for implantable bioelectronics across broad pH environments”, was published in Nature Communications, in January, 2025.  

Wearable and implantable bioelectronics that interface with various biological tissues and environments have a wide range of applications, including pain management, electrophysiological mapping and stimulation of cardiac tissue, and gastrointestinal monitoring and modulation. These biological tissues and environments span a broad pH range, from the highly acidic conditions in the gastrointestinal system (as low as pH 1.5) to the alkaline environment of chronic wounds (up to pH 8.9). The encapsulation of these systems, however, presents a major challenge, as such devices require superior barrier performance against water and ion penetration in challenging pH environments while also maintaining flexibility and stretchability to match the physical properties of the surrounding tissue. Current encapsulation materials are often limited to near-neutral pH conditions, restricting their application range. Here, Yi Zhang lab from the Institute of Materials Science and Biomedical Engineering Department reports a liquid-based encapsulation approach that achieves year-long encapsulation performance for wireless optoelectronics under highly acidic conditions (pH 1.5–4.5). This approach also achieves high optical transparency, stretchability, and mechanical durability. This liquid-based encapsulation strategy is broadly applicable to a range of implantable bioelectronics, particularly in challenging acidic or alkaline conditions.

Congratulations to first co-authors, Xiaoting Xue and Xincheng Zhang, of the Zhang Research Group.

Dr. Xiangyi Xi

While completing her bachelor’s degree in Macromolecular Materials & Engineering at Zhejiang University, China, Xiangyi Xi became interested in biotech research. Though she wasn’t sure what specific area of research she planned to pursue, she was inspired by a seminar given by UConn Polymer Program professor Luyi Sun. Later, she met Professor Tom Seery, and these meetings with faculty from another hemisphere led her to Polymer Science at the Institute of Materials Science.

After starting the Ph.D. program in Polymer Science, she joined the Professor Fotios Papadimitrakopoulos research group to help create glucose sensors. She enjoyed the multifaceted aspects of the research which included engineering, polymer science, biochemistry, as well as electrochemistry. She particularly enjoyed implementing new electrochemical testing techniques into biosensor research. The statistical nature of the research led Xiangyi to an additional unexpected degree. Xiangyi also completed a master’s degree in Biostatistics. Due to the multidisciplinary aspects of the research, Xiangyi was consistently stretching her skillset.

Looking back, Xiangyi learned more than expected during her years at UConn and gained the priceless skill of working independently. She completed her defense, “Continuous Glucose Monitoring Calibration and Metabolic Patterning”, in December 2024. In January 2025, Xiangyi joined the Yale School of Public Health, working in biostatistics.

 

Alumni Spotlight: Dr. Hailin Fu

Dr. Hailin Fu graduated in 2012 from Nanjing University with a bachelor’s degree in chemistry before pursuing a Ph.D. in Polymer Chemistry through the Polymer Program at the UConn Institute of Materials Science. She completed her Ph.D. in 2018.

In September of 2024, after conducting postdoctoral research at both the University of California, Berkeley, and Eindhoven University in the Netherlands, Fu began work as an Assistant Professor at Westlake University in Hangzhou, China.

IMS News reached out to Professor Fu with a few questions about where her educational and research journeys have taken her so far, and how she hopes to apply what she has learned going forward.

Dr. Hailin Fu
Dr. Hailin Fu

IMS News: Your educational journey was taken all around the world. From receiving your Bachelor’s in your home country of China, to earning your Ph.D. at UConn, to conducting postdoctoral research in both California and the Netherlands. What benefits did you derive from studying in such a wide variety of locations?

Fu: It gave me opportunities to think about things from different points of view and to break some stereotypical thoughts. I experienced different styles of learning, working, research, and life. The more places I went, the more I reflected on what kind of person I wanted to be. At UConn, I found my passion for outdoor activities and gained confidence and curiosity through exploring different fields of science.

IMS News: Much of your recent and ongoing research seems to involve the relationship between supramolecular polymers and water. What compelled you to study this and what have you discovered so far?

Fu: Water and supramolecular polymers are important components of life. Some good examples are cytoskeletons in cells and fibers in muscles. I’m compelled to study supramolecular polymers and water for my keen interest in life.

We discovered the liquid-liquid phase separation (LLPS) phenomenon of synthetic supramolecular polymers, which is somehow ignored or left out by the supramolecular polymer field. Supramolecular polymers can form into tactoids and arrange themselves in a highly ordered way in the solution through LLPS, opening possibilities for a range of new materials, from nanoscopic soft matter to highly structured aqueous solutions. The new discovery also applies to the liquid crystalline field. It serves as the magnified analog to small molecule liquid crystals and introduces more chemical diversity and tunability compared to biomolecular filament-based liquid crystals.

IMS News: Where can we see concepts from your current research in everyday life, and which industries would you hope to see applying your research in the future?

Fu:  The formation of liquid droplets in vinegar and oil is a typical example of the liquid-liquid phase separation phenomenon. Water can also form into liquid droplets in the presence of some macromolecules. Lots of liquid droplets (also called “membraneless organelles”) in cells are considered to be formed by the LLPS of proteins, including DNA and RNA. Like macromolecules, supramolecular polymers can drive the LLPS of water. The phase separated state of supramolecular polymers may also be related to liquid crystals formed by rod-like filaments like amyloid fibrils, microtubules, cellulose, etc.

We think this phenomenon may help generate ordered and dynamic materials with long-range orders. Considering the noncovalent nature of supramolecular polymers, high chemical diversity through modular stacking, high tunability with stimuli response, and high recyclability can be achieved simultaneously. It may be used to generate biomaterials that can interact with cells in a dynamic and responsive way. Combining functions and long-range order together, it also has the potential to be used to make optoelectronic materials with better performance.

IMS News: I read that you decided to go to the Netherlands after encouragement from UConn Professor Yao Lin. What advice do you have for prospective Ph.D. students on building this high level of trust with their professors?

Fu: I would say communication is the most important thing. Besides the weekly individual meetings, which are at least one hour long, Prof. Yao Lin and I had many other discussions. Encouraged by continued feedback and conversations, I started to be more open in asking questions or sharing concerns. Trust is built gradually through years-long interactions. Prof. Yao Lin had visited the Netherlands during his sabbatical and shared his experience in our chats. This made his suggestion quite convincing.

IMS News: You recently started a new position as an Assistant Professor at Westlake University in China. Why were you drawn to a career in education, and what do you hope to accomplish in this new role? 

Fu: This new role combines both education and research. As the beneficiary of education, especially from the tutoring of my Ph.D. advisor and postdoctoral advisors, I’ve grown into a better person, and I hope to do the same for other people through education. I’d also love to work with young and creative minds to challenge new possibilities and discover new things in research. As an assistant professor, I hope to build a well-functioning and well-managed lab, do some fun and unique research, and help students to achieve success in their careers.

Dr. Jennifer Frias graduated from Simmons University in 2011 with a bachelor’s degree in chemistry and physics before pursuing a polymer science Ph.D. in Professor Douglas Adamson’s group at the UConn Institute of Materials Science Polymer Program. She completed her degree in 2016.

Dr. Frias began her career as a Research Chemist at the chemical company Solvay.  She now works as an Advanced Technology Scientist at Nye Lubricants, a manufacturer of specialty lubricants for space applications and other critical applications in the automotive, medical and semiconductor industries. 

IMS News reached out to Dr. Frias with a few questions about her experience at UConn and how it applies to her work today. 

IMS News: Why did you choose to pursue a Ph.D. in polymer science, and what particularly drew you to UConn’s program? 

Frias: “I chose to pursue a Ph.D. in polymer science as I had exposure to polymer synthesis during my undergraduate thesis research at Simmons University. In addition, I participated in a 10-week research experience for undergraduates (REU) at UConn in the IMS Polymer Program in Dr. Adamson’s lab. That experience solidified my decision to pursue further education.”

IMS News: How did the UConn faculty support you while completing your Ph.D. and research?  

Frias: “The UConn faculty were very supportive during my Ph.D. coursework and research. They invested in additional study sessions when we were preparing for our cumulative exams, and practice sessions for our oral exams to become a Ph.D. candidate. My advisor, Dr. Adamson, was very supportive, encouraging, and always available to discuss if we had a new idea.” 

IMS News: What does your day to day look like in your position with Nye Lubricants?  

Frias: “I am an Advanced Technology Scientist looking at next generation technologies to incorporate into our lubricants to enhance performance, offer more sustainable solutions to our customers, and provide a technical advantage over the competition. My day-to-day can vary by working with our internal collaborators, our R&D colleagues, or our external collaborators, such as a university. With being part of the global FUCHS network now, there are additional market segments that we serve, so every day is unique and challenging. The best part is the collaboration among the team.”  

IMS News: What industries does your work mostly serve, and where and how might we see your work/creations in everyday life?  

Frias: “Our site, based in Fairhaven MA, formulates and manufactures specialty lubricants for automotive, aerospace, aviation, and medical, to name a few. A cool example of where our lubricants end up is our NyeBar® Barrier Film on the Mars Perseverance Rover. Other examples include our damping/motion control lubricants in automotive interior applications such as sunroofs, seat tracks, knobs and shifters.” 

IMS News: As an alumna, what advice would you give to aspiring or current polymer science Ph.D. students?   

Frias: “My advisor in undergraduate always told me: ‘getting into grad school is the easy part, staying in grad school is the challenge.’ I never knew what that meant until experiencing it for myself. A Ph.D. is a marathon, not a sprint. Keep plugging along, and there is a light at the end of the tunnel. It will pay off. Dig deep!”

IMS Polymer Program Receives DoE GAANN Grant

Posted on by
Science 1 Research Center, home of the IMS Polymer Program

The IMS Polymer Program has been awarded its fourth Graduate Assistance in Areas of National Need (GAANN) grant in 10 years. The PI, Professor Mu-Ping Nieh, and co-PIs Professors Rajeswari Kasi, Yao Lin, and Anson Ma led the recent grant proposal, “Design High-Efficiency Polymers and Nanocomposites with Their Life-Cycle in Consideration (Upcycling, Recycling, Biodegradability),” with assistance from Professors Luyi Sun and Kelly Burke. The team effort was awarded $1,119,095 which is expected to support five Polymer Ph.D. students over a three-year period.

The GAANN grant was created by the Department of Education to support academically strong students with financial need pursuing a doctoral degree in specific subject areas considered “in need”. Polymer Science is considered an area of national need. Many academic areas in the STEM fields fall under this category.

The first GAANN grant for the IMS Polymer Program was awarded in 2015. Since then, the program has been awarded three additional GAANN grants. In total, the GAANN grants have provided more than $3.4 million and have supported more than 30 students during the past 10 years. The Polymer Program’s success with GAANN funding reflects the program’s achievements in research and student support that has continued for the past 60 years.
