About

I am currently a postdoctoral fellow at the Nordic Institute of Theoretical Physics (NORDITA) in Stockholm, Sweden. My research lies at the intersection of multiphase flows and cloud microphysics, with a particular emphasis on droplet collision dynamics and droplet growth in warm clouds. Recently, I have been working on stochastic paleoclimatology, focusing on understanding the causal relations among coupled climate variables and global ice volume.

I received my M.S. and Ph.D. from the Department of Applied Mechanics & Biomedical Engineering, Indian Institute of Technology Madras. My PhD research's primary focus was studying collision dynamics of particle pairs subject to a background flow (laminar & turbulent) and gravity, incorporating hydrodynamic and interparticle interactions, which have direct applications in cloud microphysics and many industrial processes.
