In August 2023 I began my current role working for the University of Maryland's Earth System Science Interdisciplinary Center (ESSIC) as a contractor at NASA's Global Modeling and Assimilation Office (GMAO). At GMAO I work with Lesley Ott and the Carbon team where we develop and utilize the Goddard Earth Observing System (GEOS) model to predict the composition of carbon dioxide and methane in the atmosphere. I also work on GMAO's MiCASA model, which provides a global high-resolution dataset of land carbon fluxes. My current role is to keep these models operational and to develop validation tools to assess their outputs, comparing them with satellite and in-situ measurements, as well as other models.

Before NASA I worked on the GeoCarb satellite mission at the University of Oklahoma where I performed spectral analysis on the detector during its development. I completed by PhD in 2017 in the United Kingdom at the University of Leicester where I also worked as a postdoc before moving to the US. This work revolved around performing and analyzing satellite retrievals for greenhouse gases and solar induced chlorophyll fluorescence from satellites such as GOSAT, OCO-2 and PRISMA.
