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.
Graduate Students
Amber Birt
Amber received her BS in Chemistry from Union College in 2022 and joined the group in Fall 2022. She is interested in measuring the composition of surfactants in marine aerosol particles and seawater using liquid chromatography and high resolution mass spectrometry. Email.
Daniel Ammer
Daniel (Dan) received his BS in Chemistry from the University of Illinois, Champaign-Urbana in 2017 and joined the group in Fall 2022. He is working on determining the composition and properties of surfactants in the sea surface microlayer and seawater. Email.
Mara Shields
Mara received her BS in Chemistry from Otterbein University in 2023 and joined the group in Fall 2023. She is interested in studying surfactant effects on the hygroscopicity of aerosols using the Humidified Tandem Differential Mobility Analyzer. Email.
Anastasia Watson
Anastasia (Stassi) received her BS in Chemistry from Chestnut Hill College in 2025 and joined the group in Fall 2025. She is interested in the chemical composition and sources of surfactants in atmospheric aerosols. Email.
Undergraduate Students
Max Miller is a fourth year Chemistry major at UGA. He is previously assisted in the measurements of hygroscopicity of aerosol with the optical trap and investigated trends in aerosol concentrations measured with the Purple Air sensors. He is currently measuring dynamic surface tensions of aerosol samples using the bubble pressure tensiometer. Max is interested in attending medical school.
J’Myya Williams is a third year Chemistry major at UGA. She is measuring the surface tension of different standards, mixtures, and samples using the pendant drop tensiometer. She is interested in pursuing forensic chemistry.
