Research

My research is in Mathematical General Relativity. In particular, my research focusses the stability problem for black holes. My Ph.D. thesis was on the Gregory--Laflamme instability of the 5D Schwarzschild black string and the construction use of conservation laws in linearised gravity. In the latter, I studied the linear stability of the Schwarzschild black hole using the 'Canonical Energy' of Hollands and Wald.
