About Me

I am currently working as a senior research associate on the joint UK-India BoBBLE project funded by NERC & MoES, at the University of East Anglia. The project is jointly led by Professor Adrian Matthews (UEA, UK) and Professor P N Vinayachandran (IISC, India).  My research involves studying how ocean dynamics influence the variability of air-sea heat fluxes in the Bay of Bengal and the resultant impact on monsoon rainfall over India. We have quantified for the first time the heat and salt transported into the Bay of Bengal by the Southwest Monsoon Current, using a combination of in-situ observations (including Seagliders) and numerical modelling (one and three-dimensional).

Previously, I worked on the NERC iSTAR project, studying how ocean dynamics drive variability in the melt rate of rapidly melting ice shelves around the Amundsen Sea, Antarctica.

My PhD was on the dynamic ocean response to the Madden-Julian Oscillation (MJO), during which I demonstrated a novel feedback mechanism through which ocean Rossby waves could initiate or amplify MJO events.

Research

I specialise in studying interactions between components of the climate system, from air-sea interaction in the tropics to ocean-ice interaction in the polar regions. I use a combination of in-situ observations and targeted numerical model observations to study the dynamics of these complex systems.
