My current research interests mainly lie in the characterisation and applications of quantum walks, with specific focus on quantum simulation of complex biochemical systems such as photosynthesis and electron transport in functional nano-materials.

A major part of my research involves numerical simulation on high performance supercomputing clusters (mainly using the Pawsey supercomputing facility in Western Australia), working mostly with Fortran and Python. In order to streamline my workflow, I developed an efficient parallel framework for simulating continuous-time quantum walks, pyCTQW, with the source code available on my GitHub page. Other tools I find useful for my work include iPython, matplotlib, the amazingly extendable SublimeText, and of course Mathematica and $\LaTeX{}$.

Outside of research, I am also employed as a tutor, lab demonstrator, and guest lecturer for undergraduate and honours physics units at UWA. I also enjoy science writing and communication - my writing has so far been featured in Australian Geographic and redOrbit.
