Her research interests broadly include the dynamics and thermo-dynamics of the northern Indian Ocean. She is currently working on the large seasonal amplitude of sea surface salinity over the south-eastern Arabian Sea and studying the dynamics behind it with the help of Ocean Dynamic Thermo-dynamical model (ODTM) developed at the Indian Institute of Tropical Meteorology, Pune.
She worked as Senior Research Fellow and later as Project Scientist at the National Institute of Ocean Technology from July, 2010 to March, 2018. During this period, she got the opportunity to work extensively with in-situ data obtained from the moored buoys deployed at specific locations in the northern Indian Ocean. She has studied the inter-annual variability of freshening of the northern Bay of Bengal and studied the impact of freshening on the intensification of the cyclonic storms formed over the Bay of Bengal. She collaboratively worked with other institutes for the validation of MODIS derived shortwave radiation and Integrated Multi-satellitE Retrievals from Global Precipitation Measurement (GPM) precipitation data. Meanwhile, she also participated in the Air Sea Interactions Regional Initiative – Ocean Mixing and Monsoons, an international, multi-institution research effort focused on understanding how upper-ocean mixing in the Bay of Bengal influences the Indian Ocean Monsoons and collaboratively worked to understand the air-sea interactions over the Bay of Bengal. Later she focused her studies on the dynamics behind the warming of the south-eastern Arabian Sea (SEAS) during the spring transition months and also looked into the association of the Indian Ocean Dipole with the warming of the SEAS. At the initial stages of her career, she worked as Project Associate at the Centre for Atmospheric and Oceanic Sciences, I.I.Sc., Bengaluru. She has worked with the Modular Ocean Model version 4 (MOM4), and conducted sensitivity studies on the amplitude of intra-seasonal oscillation of sea surface temperature over the Bay of Bengal under different river discharge scenarios. During her M.Sc. (Engg.), she has studied the phytoplankton bloom found over the southwest Bay of Bengal during northeast monsoon season and related it to the open ocean upwelling driven by Ekman pumping.
