I work mainly on black hole perturbations and quasinormal modes (QNM), alternative theories of gravity and some mathematical aspects of black holes. QNMs are solutions of linearised differential equations of general relativity describing perturbations of black holes with complex eigenvalues describing the frequency of oscillation (real part) and the damping time (imaginary part). QNMs provide important information about black hole parameters. They can also play a role in understanding AdS/CFT correspondence and some quantum aspects of black holes. Apart from these, I am also interested in AdS/CFT correspondence and its application to condensed matter systems.
