COMPUTATION × TURBULENCE × PHYSICS

I am a physicist and Postdoctoral Associate at New York University, working with Prof. Katepalli R. Sreenivasan on turbulence and quantum computing for fluid dynamics (QCFD). I study complex nonlinear systems, from turbulent flows in atmospheres and stellar interiors to quantum turbulence. I combine theory with direct numerical simulation, machine learning, and high-performance computing.

I received my Ph.D. in Physics from IIT Kanpur in 2026. My thesis, Compressible turbulent convection at extreme Rayleigh numbers, received the Outstanding PhD Thesis Award. Before joining NYU, I held a Fellowship for Academic and Research Excellence at IIT Kanpur.

Research at a glance

01 / CONVECTION Heat transport at extreme parameters Dry and moist compressible convection, scaling laws, and atmospheric flows. 02 / TURBULENCE Energy transfer across scales Shocks, spectra, fluxes, and scale-by-scale pathways in compressible flow. 03 / COMPUTATION New ways to compute fluids Scalable PDE solvers, GPU computing, machine learning, and quantum formulations of flow.

Beyond simulations, I care about mountains, movement, music, and games. A little more about me →
