**Keywords:** General relativity, analysis of partial differential equations

I am a mathematician interested in probing the nature and validity of theories of fundamental physics, in particular general relativity.

At the heart of my research is the idea that the mathematical models we use to describe physical phenomena should be stable: that is, small changes to the model at some given time should only lead to small changes in the model’s behaviour at later times. Stability is key for a model to have predictive power and is crucial for ensuring reliable numerical simulations. My research involves determining whether stability holds for many interesting models derived from general relativity, string theory, particle physics and cosmology. At a concrete level, this involves the analysis of partial differential equations, combined with some differential geometry and a bit of physical intuition.

Originally from Australia, I took my undergraduate studies in mathematics at the University of Cambridge. After a year teaching at the African Institute for Mathematical Sciences in Cape Town, I completed my PhD at the University of Edinburgh. Since October 2020 I started my first postdoc as a Herchel Smith Postdoctoral Research Fellow at the Department of Pure Mathematics and Mathematical Statistics and as a Junior Research Fellow at Darwin College.
