Amanda A. Frossard

Amanda joined the faculty at UGA as an assistant professor in Chemistry in Fall 2017. She received a BS in Chemistry from UC Berkeley in 2008, where she worked as an undergraduate researcher with Allen Goldstein. Amanda completed her PhD in 2014 at Scripps Institution of Oceanography, at UC San Diego. There she worked with Lynn Russell studying the organic composition of marine aerosol particles. Amanda worked with Ronald Cohen at UC Berkeley as a postdoctoral scholar in Chemistry, where she built an aerosol optical trap to measure particle hygroscopic growth. Email.

Work in the Frossard Lab at UGA is focused on understanding the composition and properties of surfactants in atmospheric aerosol particles and how these surfactants influence the hygroscopic properties of aerosol particles.
