• Prof. Aaron Harrison is a physical and analytical chemist specializing in atmospheric and environmental chemistry. Originally from Little Rock, Arkansas, he earned his B.Sc. in Chemistry from the University of British Columbia in 2008 and his Ph.D. in Chemistry from the University of California, Berkeley in 2014, working with Prof. Dan Neumark on photochemical reaction dynamics. He then completed a postdoctoral fellowship at the University of New South Wales in Sydney, Australia with Prof. Scott Kable, where he studied the atmospheric photochemistry of carbonyl compounds. Before coming to Trinity, Prof. Harrison was a Teaching and Research Fellow at Chapman University, collaborating with Prof. Warren de Bruyn on aerosol photochemistry and spectroscopy. He joined Trinity University as an Assistant Professor of Chemistry in Summer 2025.
