My research interests are varied and are mainly focused on climate dynamics, predictability, data assimilation, and geophysical fluid dynamics.

The main focus of my work is currentlyÌýin gaining a better understanding of processes that impact extreme weather especially on subseasonal-to-seasonal timescales as well as better modeling of theÌýÌýand its teleconnectionsÌýusing global climate models (such as the Community Earth System Model () and ECMWFÌý).ÌýI am actively working onÌýstochastic parameterization for better representation of physical processes in climate models.ÌýAnother focus of my work isÌýon data assimilation in coupled ocean-atmosphere models. In the past, I have worked on assimilating ship cruise and satellite observed data into a regional eddy-permitting ocean model of the South East Pacific to better understand mesoscale ocean processes in this region using a regional ocean model calledÌý.ÌýI also study nonlinear data assimilation techniques to improve upon the Ensemble Kalman Filter and Adjoint-based methods in data assimilation into simplified nonlinear models of the atmosphere and climate.

I am also a visiting scholar in theÌýÌýgroup in theÌýÌýat theÌý.ÌýI graduated fromÌýtheÌýÌýatÌýÌýin 2012.Ìý I previously obtained M.Sc. (Engg.) fromÌýÌýin 2006 and B.Tech fromÌýÌýin 2004.
