Research Interests

The use of space-based instruments to quantify carbon dioxide emissions from megacities is increasing around the globe. Several instruments such as GOSAT, GOSAT-II, OCO-2, OCO-3, and TanSat are being regularly used to better understand urban aspects of the carbon cycle. Upcoming missions include the GeoCarb project (NASA) and CO2M (ESA). My work focuses on using OCO-3 data to dissect urban emissions at the sub-city level. That is, I seek to understand how carbon dioxide emissions from cities change throughout space and time.
