Biswarup Biswas currently works at IIT Delhi, where he works with the group of Prof. Harish Kumar. He earned his PhD from SRM Institute of Science and Technology under the supervision of Prof. Ritesh Kumar Dubey. Before that, he completed his MSc from IIT Madras.

He works in the area of computational methods for Balance Laws. Most of his PhD works are on the area of higher-order provably stable methods for hyperbolic conservation laws. Currently, he is working on stable schemes for various astrophysical problems.

Some of his current interests are:

Entropy Stable schemes, DG schemes, Stability of numerical schemes for Hyperbolic Conservation Laws, Deep learning, Numerical schemes for Hamilton Jacobi equations, Numerical schemes for Reaction-Diffusion equations.
