Senior Scientist at Govt R&D Lab, PhD from IISc, Expert in CFD, FEM and Numerical Analysis, 10+ years of experience

Profile Summary

I am a Senior R&D Scientist at a Govt R&D Lab and Ph.D. Mathematician (IISc, Bangalore) with over 10 years of experience in Computational Fluid Dynamics (CFD), Finite Element Methods (FEM), and High-Performance Computing. Currently working at a premier government research laboratory, I specialize in developing advanced numerical solvers for complex physical systems, including internal ballistics, solid propellant combustion, and multiphase flows. My expertise lies in bridging the gap between theoretical mathematics and practical engineering challenges. I have successfully led projects involving propellant geometry optimization and Physics-Informed Neural Networks (PINNs) to accelerate simulation timelines. Prior to my current role, I served as an Assistant Professor and Postdoctoral Fellow at IIT Bombay and TIFR-CAM, where I published extensive research on error estimates and variational inequalities. Core Services: 1. Simulation & Modeling: Custom CFD/FEM solvers, Heat Transfer analysis, and Internal Ballistics modeling. 2. Algorithm Development: Converting complex mathematical papers into optimized Python/MATLAB code. 3. Scientific ML: Implementing PINNs and Neural Operators for accelerated physics simulations. I am looking for challenging R&D projects where I can apply rigorous mathematical techniques to solve real-world engineering problems.
