Theoretical physics, Gravitation, Quantum fields in curved space, Wormholes, Quasi-normal modes, Geometric methods in physics…

To UG/PG (B.Tech/IMSc) students— Feel free to contact me if you are interested in working with me. Currently, I am focusing on (not exclusively) applications of geometric methods (tools used in gravitational physics) in condensed matter / statistical physics. Please look up the BIT/ Physics Dept webpage for (limited) internship opportunities.
