I graduated from the University of Bristol in 2007, where I worked as a research assistant for one year before I was awarded a scholarship to conduct my Ph.D research. My doctoral thesis was supervised by Prof. Andrew Radford (University of Bristol) and Dr Andrew Young (University of Exeter), and then examined by Prof. Clive Catchpole and Prof. Innes Cuthill.

Since 2012, I have held a number of postdoctoral positions, and in 2019 I was awarded a Marie Curie fellowship.
