I'm about one third cosmologist and two thirds general relativist. I am mostly interested in figuring out if nonlinear general-relativistic effects can help improve our understanding of the Universe. I spend most of my time writing code and running simulations, like that one up there.
I'm currently the Herchel Smith Fellow in DAMTP at the University of Cambridge, UK. I work in the Centre for Theoretical Cosmology in the Relativity & Gravitation group.
Previously, I was at Monash University in Melbourne, Australia, doing my PhD under the supervision of Daniel Price and Paul Lasky. My PhD thesis is publicly available here.
