I pursued my PhD from the Space Physics Laboratory of VSSC (ISRO), Thiruvananthapuram India. Soon after the completion of my PhD, I got an opportunity to work as postdoctoral research associate at Chiba University, Japan and University of Arizona, USA.

My research area focuses on the distribution of the trace gases like methane (CH4), nitrous oxide (NOx), carbon monoxide (CO) and aerosol based on in-situ measurements and satellite observations. More specifically, I am interested in elucidating the utility of air quality observations (CO, NO2) especially remotely sensed retrieval products and ground based (TCCON) in disentangling the anthropogenic sources of Greenhouse gases (CO2 and CH4).

Spatio-temporal distribution of pollutants and precursors over India: Air pollutant emissions in India lead to severe air quality degradation that has adverse effects on human health and the environment. It is essential to obtain accurate estimates of the emission of these pollutants and understand the influence of variability associated to meteorology or dynamics. The main objective of this work is to develop a comprehensive understanding of the pollutant precursors and transport pathways and mechanism over India using the observations from multiple space-based platforms (TROPOMI, IASI) and mechanistic information from the chemical transport model (GEOS-Chem).
