Yao Lin, Associate Professor of Chemistry in the Polymer Program of the Institute of Materials Science, has become very passionate about chemistry and polymer science—and about encouraging intercontinental collaboration on it. With a background in chemistry, polymer and molecular biology and a degree from Fudan University, China, Dr. Lin is interested in researching bio-inspired materials for the future and developing educational opportunities for students at home and abroad.
Dr. Lin and his lab are currently working on two projects which mimic certain natural protein polymers and complex enzymes to create synthetic, bio-inspired materials. One direction is trying to understand the cooperative folding and interactions between complex macromolecules containing synthetic polypeptides to mimic the dynamic process of protein polymerization. According to Dr. Lin, the protein polymerizations provide the filaments with excellent mechanical strengths for our muscles, our cells, and contribute to cell movement. The reason cells can move is partially because these protein fibers can grow on one end, and shrink on the other end.
The other direction involves mimicking an enzymatic structure that forms “teams” that can degrade cellulose into sugars. When bacteria develop complex structures like nano-machines that recruit six to ten different types of enzymes into a team, they can work much more effectively than individual enzymes. Dr. Lin and his group are researching whether they can replace that type of protein scaffold with synthetic polymers, and thus design the chemistry at interface between these polymers and proteins. This will allow them to recruit different engineered proteins in an organized manner.
Professor Emeritus of Chemistry Michael Smith, who recently retired after more than three-and-a-half decades of service, has made teaching organic chemistry to nearly 400 students seem easy. As Smith discusses his tips and tricks for managing a large class, it is difficult to picture him in any other profession. As Department Head Christian Brückner notes, “Few instructors are able to teach such large classes, and even fewer can command the stage of such large classrooms as effectively as Smith…His retirement from UConn leaves a large gap.”
But Smith did not originally imagine himself in academia. After graduating from Virginia Tech with a B.S. in Chemistry, he became an Analytical Chemist at Newport News Shipbuilding & Dry Dock Co., performing water analysis to keep the primary and secondary coolants of navy ships within specifications. When he realized that he wanted something different out of his career, he decided to go back to school to earn his Ph.D. Even then, he was not considering becoming a professor. “It just never entered my head that it was a possibility,” Smith recalled. “As a matter of fact, when I first went to graduate school, I had the idea to work in industry. That was really all I ever thought about. It wasn’t until I taught and I liked graduate school and I liked doing research.”
Instead, Smith entered into a long career in academia, leaving a lasting legacy as a teacher, author, and mentor at UConn. He joined the Department of Chemistry as an Assistant Professor in the fall of 1979, just two years after earning his Ph.D. Over the course of his tenure, Professor Smith has mentored 15 Ph.D. students, 13 M.S. students, and approximately 90 undergraduates. He has taught 75 semesters worth of courses, including both halves of undergraduate organic chemistry and graduate courses on organic synthesis and organic reactions. In addition to teaching at UConn, he has also taught courses at companies like Pfizer and Bristol-Myers Squibb, as well as courses abroad in Spain and China. In the midst of all this, Dr. Smith found the time to author 25 books – which have sold in excess of over 100,000 copies.
A research team led by Professor Flavio Maran of the University of Padova (Italy), who is also a Research Professor with the Chemistry Department at UConn, reported a breakthrough in the creation of very high quality crystals formed of gold nanoparticles via electrocrytalization. This work was done in collaboration with Professor Kari Rissanen of the University of Jyväskylä (Finland). They published their recent work in the Journal of the American Chemical Society. Their recent discovery has been featured in several news outlets.
Adjunct Professor Frank Galasso contributed to the article First-Hand:Discovery of Superconductivity at 93 K in YBCO: The View from GroundZero, which attempts to unravel the complicated history of superconductors.
Dr. Challa Kumar has received additional funding from CLAS and the Department of Chemistry to supplement the Provost’s Open Education Resources Award which he received for the development of an open source text book in Physical Chemistry. Dr. Kumar will be developing the open source text book from scratch as there are none currently available on the subject (Rhonda Ward, IMS).

Dr. Tomoyasu Mani is the recipient of a 2016 Blavatnik Regional Award for Young Scientists.
The Blavatnik Award honors outstanding postdoctoral scientists from institutions across New York, New Jersey, and Connecticut. Three winners and six finalists are chosen from the fields of Life Sciences, Chemistry, and Physical Sciences and Engineering. Mani is being recognized for his “advances in the understanding of electron transport occurring in organic photovoltaics used in solar energy capture and conversion!”
