Postdoctoral Researcher

Biography

Elyse was born and raised in the greater LA region and focused her PhD research on understanding air quality in the LA Basin. She used chemical transport models to understand pollutant formation, focusing specifically on updating the chemical mechanism to represent organic aerosol and ozone formation from consumer product emissions. At JPL, she aims to understand global ozone formation by analyzing regional ozone trends using satellite products from the TROPESS project combined with data assimilation results.
