Research interests:

Atmospheric Chemistry Modelling, Atmospheric-Climate interactions, Aerosol-climate interactions

Career history:

I was a Junior Research Fellow at the CSIR-National Physical Laboratory, India, where I studied long term Spatio-temporal variations of surface Black carbon concentrations over New Delhi using Aethalometer measurements. I also briefly worked as an air quality researcher at a think-tank based in Bengaluru, India. I helped in developing concept notes, proposals, strategic planning, and grant writing processes for the three major clean air projects in the city.

Active research projects:

Black Carbon (BC) particles are emitted into the atmosphere as a result of incomplete combustion. They strongly absorb solar radiation and are one of the important short-lived climate forcing agents. Here, we use the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem) to understand the seasonality of BC emissions, transport mechanisms and the effects of wet and dry deposition on the total BC distribution over South Asia. The study underpins the present knowledge about Spatio-temporal distribution of BC, which has broad implications for forecasting fog events and planning mitigation strategies, for urban regions where BC concentrations are particularly high.
