I'm a PhD student in the Visual Geometry Group at Oxford University, co-supervised by Andrew Zisserman and Andrea Vedaldi. During my PhD, I have also spent time interning with Ishan Misra at FAIR Labs in New York.

I previously studied Engineering Science, also at Oxford, graduating in 2018. In between graduating and beginning my PhD, I was fortunate to work at CuriousAI in Helsinki (now acquired by Apple) and Founders Factory in London. I have since continued to work with start-ups when time allows. My research is funded by a Facebook AI Research Scholarship.

My research focuses on Open World Learning - I am interested in learning representations from limited (labelled) training sets which can generalize to 'open world' data, where the data distribution (e.g categories or domain) may be different.
