About Me

I am a postdoctoral researcher at the Department of Mathematics, Indian Institute of Science Education and Research Thiruvananthapuram where my mentor is Professor K. R. Arun. My research interests are in Partial differential equations of Hyperbolic type and Navier Stokes equations.

Previously, I was postdoc at Indian Institute of Science Education and Research Pune, postdoc at the Remote lab in Armenia under Ghent University, Assistant Professor at Atria Institute of Technology under Visvesvaraya Technological University, Assistant Professor at Presidency University and Part-Time Lecturer at Mount Carmel College under Bangalore University.
