About

Presently, I'm working in the area of Theoretical Physics with a special focus on computational modelling & simulation of gravitationally stable stellar structures. It includes decoding the governing dynamics of Compact Stars, Strange Stars, Quark Stars, Neutron Stars, Black Holes & Hybrid Stars (with non-linear coupling of Dark Energy & Dark Matter) using GTR & MOG in QCD framework.

Disciplines : Theoretical Physics, Mathematical Physics, Computational Physics, Geometry and Topology, Applied Mathematics, Algorithms, Parallel Computing

Skills and Expertise : Theoretical Physics, Field Theory, Gravity, Mathematical Methods, Differential Topology, Nonlinear Dynamics, Computational Simulations.

Programming Languages: Mathematica, R, Python, Excel-VBA, JMP-SAS, C.
