Lexy LeMar

Lexy LeMar is a PhD candidate in atmospheric chemistry whose primary research interests are in the process of oxidation. Specifically, Lexy studies the oxidation of volatile organic compounds (VOCs) in the atmospheric aqueous phase through laboratory research and MATLAB-based mechanistic modeling. With the support of a MathWorks Fellowship, she will utilize her novel model to obtain kinetic parameters from chamber and bulk aqueous phase experiments and gain new mechanistic insights on oxidation pathways. She is also developing a model for multiphase experiments involving gas-phase and aqueous aerosol-phase kinetics, with the goal of obtaining rates and products of individual steps from the time-dependent concentrations of a given chemical system. Lexy’s work has great potential to expand our understanding of the atmospheric chemistry of particle formation and growth, processes with profound impacts on air quality, human health, and climate.
