Christopher W. Leishman, PhD
Dr. Leishman grew up in Albuquerque, New Mexico. He studied physics and applied math at the University of New Mexico, where he became fascinated with quantum dynamics in biological energy transport processes. After graduating, he moved to Oregon, earning an additional bachelor’s degree (Chemistry) at Portland State University while performing computational modeling of sensitizing dyes and photoactive polymers for solar cells in the research group of Prof. Carl Wamser. In July 2016, he earned his Ph.D. in physical chemistry from the Department of Chemistry of Washington State University in Pullman, Washington, under the mentorship of Prof. Jeanne L. McHale. In his doctoral research, he coordinated resonance Raman spectroscopy with nanoscale imaging to distill insights into relationships between structure and optical properties of supramolecular porphyrin aggregates. He published the findings from these investigations in an interlinked series of three first author papers. Dr. Leishman joined Prof. Eisele’s research group as a postdoctoral researcher in September 2016 at the City College of New York, where he is working on structural and optical studies of energy and charge transfer dynamics in composite nanoscale systems including hybrid excitonic and plasmonic materials. He is driven by a vision to engage cutting-edge optical spectroscopy, microscopy and theoretical investigations to enable future advances in sustainable energy.
