I am a Postdoctoral Associate in the Department of Mechanical and Aerospace Engineering at the Tandon School of Engineering, New York University, working with Prof. Katepalli R. Sreenivasan on quantum computing for fluid dynamics (QCFD). Prior to this, I had a Fellowship for Academic and Research Excellence (FARE) at IIT Kanpur, where I also completed my Ph.D. in Physics. My doctoral research, supervised by Prof. Mahendra K. Verma and Prof. Rajesh Ranjan, focused on compressible turbulent convection at extreme Rayleigh numbers.

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.
