About me

I am a third-year PhD student at the University of Warwick under the supervision of Prof Daniel Král'.

Before that I did Part III of the Mathematical Tripos at the University of Cambridge, specialising in Combinatorics and Number Theory. I wrote my Part III essay on the topic of Robust Expansion in Graphs under the supervision of Prof Andrew Thomason.

Before that I was an undergraduate at Murray Edwards College, University of Cambridge.

You can find a copy of my CV here.

Here is a list of events I have attended, including upcoming events.

Research

My interests lie mainly in the area of extremal combinatorics. In the past I have looked at ways to decompose the edge set of a given graph into small or sparse subgraphs, limits of combinatorial objects and their applications to extremal problems, and graph tilings in various settings.
