Biography

I am a Postdoctoral Research Fellow in the School of Physics at UNSW Sydney, working with Richard Morris on stochastic processes and statistical physics in cell biology.

My current research is on noise-induced manifolds, where strong, state-dependent noise drives a system onto a few sets on which the noise vanishes and slower dynamics carry it along and between them. I am developing a reduction of such systems to switching processes, with applications to gene regulation and epigenetics, and I collaborate with experimental groups on transcription dynamics and T-cell migration.

I did my PhD, “Stochastic Active Flows”, at the University of Bath with Tim Rogers and Paul Milewski, and before that read Theoretical Physics at the University of Manchester.

In my spare time I enjoy playing football (soccer), running, walking and exploring all the beaches Sydney has to offer.
