I am a Stephen Hawking Fellow at the
University of Birmingham, in UK.

I study fundamental physics and astrophysics that can be explored using gravitational wave observations. I am particularly interested in black holes, and my research primarily involves gravitational waves emitted when two black holes collide.
I spend my spare time exploring art — I love to paint, explore art galleries and photograph sculptures. I am also looking for opportunities to collaborate with artists and art-entusiasts to explore projects at the interface of art and science. Please feel free to write to me if you would like to brainstorm with me on this (or anything else).
Research Interests
- Understanding the nature of black holes
- Testing the general theory of relativity
- Probing strong field gravity
- Developing gravitational wave data analysis for current and future detectors
- Testing for exotic compact objects and black hole mimickers.
