About me

As geophysical fluid dynamics researcher, I work to better understand the ocean’s circulation and how it regulates heat and mass transport including polar mass loss. Our group develop the fundamental physics of deep overturning circulation of the oceans including the complex dynamics of melting of Antarctic ice-shelves in a warming world. We use cutting-edge high-performance computing will be used to understand key mechanisms and contribute to the formulation of better ocean and climate models.

RESEARCH GROUP

Myself

I obtained my B. E. in Mechanical Engg. from Jadavpur University, Kolkata, India in 2006. I was then at JNCASR, Bangalore where I did my M.S. (Engg.). My M.S. thesis was focused on the rheology of frictional Granular Shear Flow using MD simulations.

In 2007, I joined University of California, San Diego as a PhD student at the department of Mechanical and Aerospace Engineering. My PhD work was focused on turbulence and internal waves in tidal flow over topography via numerical experiments (both LES and DNS). I was a part of the Geophysical Fluid Dynamics Group @Research School of Earth Sciences, Australian National University (Canberra) from 2012 to 2018.

Recently, I am Associate Professor at Mechanical Engineering Department in the University of Melbourne and Assistant Professor at Centre for Atmospheric and Ocean Science, Indian Institute of Science.

My hobbies include painting, photography and listening to music.
