Biswarup Biswas 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.

He loves doing coding in Matlab, C++, Python, Fortran and Julia.
