I am a PhD student at the Mathematical Institute, University of Oxford, working on role extraction, diffusion, and optimisation on networks. There are many fundamental problems in industry that are also of great research value. With our industrial partner Tesco, we are particularly interested in the retail industry, where one primary problem would be to understand the intrinsic relationships between products, including complements and substitutes.

I am part of Cohort 5 in the EPSRC Centre for Doctoral Training for Industrially Focused Mathematical Modelling (InFoMM).

My project is supervised by Prof. Renaud Lambiotte.
