About Me

Welcome to my webpage! I am a second year Ph.D. student in the Department of Pure Mathematics and Mathematical Statistics at the University of Cambridge. My supervisor is Professor Mihalis Dafermos.

My research is in Mathematical General Relativity.

You can reach me via email at scc73 at My office is D0.12 at the Centre for Mathematical Sciences.


My research thus far has focussed on stability problems in General Relativity. In particular, I have studied the stability problem of the 5D Schwarzschild Black String.
