I am a PhD student in the Condensed Matter Theory Group at Imperial College London, supervised by Prof. Matthew Foulkes (ICL), David Pfau (DeepMind), and James Spencer (DeepMind). My current research centers on leveraging the power of deep neural networks to solve the many-body Schrodinger equation -- the fundamental equation of everyday physics, from which all of chemistry and biology may be derived. More broadly, I am enthusiastic about applying deep learning to the natural sciences in the hope of achieving the same radical progress that has been realised in fields such as computer vision and natural language processing.
Previously I obtained my Masters degree from the University of Bath, supervised by Dr. Anton Suslov (now Cambridge TCM), where I studied topological excitations in fluids with odd viscosity. I still occasionally moonlight in the realm of topological physics, given it is both fun and fashionable. During my undergraduate studies I also spent some time in the world of experimental physics, spending just over a year at the ISIS Neutron & Muon Source where I was centrally involved in a project to upgrade the LET spectrometer for polarised neutron spectroscopy experiments.
