Research Interests

In my research I am focussing on theoretical work to understand the extreme environments around black holes and neutron stars. One aspect of this is the study of gravitational waves that has very recently gained substantial impetus due to the seminal LIGO detections. Another aspect is the study of light that emanates from these sources including their immediate vicinity. In my work I am establishing concrete theoretical predictions for how gravitational waves from such sources can look like and how a potential electromagnetic counterpart can manifest itself to other observatories. My recent work involves tidally induced neutron star oscillations as gravitational wave sources, and electromagnetic signals during the inspiral and merger of two black holes embedded in a turbulent magnetized disk. In addition in my work I predict how black hole images and other radio signatures will look like in the Radio and a large part of my work is concerned with developing a parameter estimation tool for the Event Horizon Telescope collaboration.
