Profile Summary

I have done my Ph.D. Computational Mathematics, interested in studying the modeling and simulation of the various physical phenomena. The aim of the study is to approximate the solutions of such phenomena numerically in the absence of the exact solutions. I have studied the various models from Physics, Chemistry and Biology. Few of the studies include modeling & simulation of Multi-Physics Systems, e.g. Hydrodynamical Model for Semiconductor Devices in which we predict the quality of semiconductor material depending on the various parameter to develop high-speed computer, navigation systems, digital watches etc. In Chemical Engineering, I studies the Population Balance Models which deal with the Batch and Coupled Crystallization. In Computational Biology study of the Cancer Growth Models were studied. Currently, I am working on the mathematical modeling of coronavirus disease (COVID-19) with the help of the Influenza Mathematical Model. Apart from research I have done a considerable amount of teaching at different places. I have taught courses to undergraduate, graduate and post-graduate levels. Some of the courses include; Calculus, Linear Algebra, Ordinary Differential Equations, Partial Differential Equations, Numerical Analysis, Engineering Mathematics, Computational Linear Algebra, Numerical Solutions of Differential Equations. I have also supervised and co-supervised research students.
