Research interest

My principal research interests include linear perturbations of black holes and related topics, such as quasinormal ringing, stability, wave scattering and Hawking radiation.
I also study general properties of black hole and other compact objects in alternative theories of gravity and possibility of testing General Relativity through observations of phenomena in their vicinity.
