Dr. Rajesh Ranjan

Dr. Rajesh Ranjan is an Associate Professor in the Department of Aerospace Engineering at IIT Kanpur, where he leads the Aeroscience Computations & Analysis Lab (ACAL). His work brings together high-fidelity simulation (DNS/LES), hydrodynamic stability, and scientific machine learning to understand and control complex flows across turbomachinery, high-speed aerodynamics, and fundamental turbulence.

His group develops scalable, GPU-enabled CFD solvers — ANUROOP, PRAVAH and DHARA — along with underPINN, an in-house physics-informed neural-network framework. He was previously a postdoctoral scholar at The Ohio State University and earned his Ph.D. at JNCASR, Bengaluru under Prof. Roddam Narasimha and Prof. S. M. Deshpande. He is also co-founder and director of Vayusoft Labs, an IIT Kanpur–incubated startup, and serves as a technical mentor for Spacephilic.
