I am a Fellowship for Academic and Research Excellence (FARE) Fellow in the Department of Physics at IIT Kanpur, where I also completed my Ph.D. My doctoral research, jointly supervised by Prof. Mahendra K. Verma and Prof. Rajesh Ranjan, focused on compressible turbulent convection at extreme Rayleigh numbers. Currently, I am working on high-resolution simulations of moist turbulent convection in Earth’s troposphere, quantum and classical Euler turbulence, and scale-by-scale energy transfer.

I specialize in building scalable, custom simulation software from the ground up (such as DHARA) to run large-scale Direct Numerical Simulations (DNS) on high-performance supercomputers using MPI and GPU acceleration. My work bridges fundamental fluid dynamics and astrophysical flows with high-performance computation.

Outside of research, I enjoy trekking in the Himalayas, weight training, running, music, and gaming.
