I am a DPhil student in Machine Learning at the Oxford-Man Institute, my background is in mathematics, statistics and computer science. I am supervised by Dr. Xiaowen Dong and worked closely with Prof. Pietro Lio, my focus is in developing Gaussian processes on graph structured data. Currently, I am working with kernel functions on graph spaces applied to supervised and semi-supervised graph prediction problems, where models are designed to make use of various graph convolutions and exhibit transductive qualities for superior performances. I was awarded a PhD studentship from the EPSRC Doctoral Training Partnership (DTP) scheme.
I obtained First Class honours MSci in Mathematics at Imperial College London. In addition to machine learning, I have interests in a range of topics including Monte Carlo and Quasi-Monte Carlo, option pricing and stochastic simulation.
