2021 Coblentz Student Awardee – Christopher Warkentin
Chris Warkentin is currently a Ph.D. candidate in experimental physical chemistry at the University of Minnesota. Prior to his academic career, he found work building trails in the Appalachian Mountains, restoring wetlands in the Midwest, establishing a sustainable farm, and managing a custom construction shop. These experiences informed his interest to pursue a career in sustainability and his eventual return to collegiate studies at Indiana University South Bend. Here his research career began, exploring a range of interests in chemistry and physics. As a SMART Research Fellow, under the advisement of Dr. Grace Muna, he developed nickel-palladium modified glassy carbon electrodes for the electro-analytical detection of steroid hormones in local surface waters. In 2017, he earned a BS in Chemistry with minors in Physics and Mathematics from IUSB and moved to Minneapolis to pursue his doctoral degree in Chemistry at the University of Minnesota under the advisement of Dr. Renee Frontiera. While pursuing his Ph.D., he obtained his master’s degree in Chemistry in 2018.
Today, his research interests center on using surface-enhanced Raman spectroscopy (SERS) to investigate the dynamics of plasmon-driven chemistry in a variety of plasmon-molecule systems. A better understanding of plasmon-molecule interactions could aid in the rational design of new plasmon-based green catalysts for more sustainable chemical production and solar energy generation. Chris’ work uses ultrafast (ps) time-resolved SERS and steady-state (ms) SERS in order to understand both the fast energy-transfer dynamics that occur on the timescale of plasmon decay and the slower reaction kinetics that result from the cumulative effects of continuous irradiation. His research, in collaboration with theorists and material scientists, has revealed new insights into nanoscale spatial control of plasmon-driven processes, ultrafast plasmon-induced charge transfer, and upconversion applications with new plasmonic materials.
Chris has earned a number of awards during his tenure at the University of Minnesota, where he is currently an Institute on the Environment Renewable Energy Commercialization Fellow. He is an active member of the Analysis and Compliance committee for the Departments of Chemistry and Chemical Engineering and Materials Science Joint Safety Team and involved with various student groups within the department.
