I am a postdoctoral scholar in the Wennberg group at the California Institute of Technology. My primary research focuses on developing the new retrieval version for the Total Carbon Column Observing Network (TCCON). Once that is complete, I plan to use that retrieval, in conjunction with the OCO-3 instrument on board the ISS, to investigate methods of inferring CO2 photosynthetic uptake from measurements of diurnal cycles of CO2. I am also working on using NO2 measured from the TROPOMI satellite instrument to probe how urban chemical lifetimes changed during the COVID-19 pandemic, and what this can tell us about how the optimal way to improve air quality varies between cities.
My previous research focused on the development and application of space-based measurements of NO2, and led to the development of v3.0B of the Berkeley High Resolution (BEHR) NO2 product. During my Ph.D., I used the BEHR product along with other satellite datasets to study NOx emissions from lightning and the oxidative chemistry in urban plumes. I continue to be interested in the combination of satellite measurements with forward and inverse models to study anthropogenic and natural emissions of trace gases to the atmosphere and the chemistry that controls the ultimate fate of those trace gases.
