Personal profile
Biography
I joined the ICG in 2021 as a PhD student with an STFC fellowship. Before that I completed the MSc in Quantum Fields and Fundamental Forces at Imperial College London and before that I obtained my undergraduate degree from King's College London in Physics and Philosophy.
Research Interests
My research interest lies in theoretical gravity and comsology. I investigate modifications to general relativity and develop frameworks to test them with observations. In the context of gravitational waves, I use black hole perturbation theory to find out what we can learn about the fundamental nature of gravity in the ringdown quasinormal modes. I have written user-freidnly and adaptable Mathematica notebooks including all relevant computations.
I am a member of LIGO.
