About Me
I am a postdoctoral research assistant at the Mathematical Institute of the University of Oxford working with Peter Keevash. Until December 2017 I was a Research Fellow (postdoc) at the Mathematics Institute of the University of Warwick and DIMAP with Oleg Pikhurko, working on the ERC project Extremal Combinatorics. Previously I was a Ph.D. student working in the Graph Theory and Combinatorics group at the University of Birmingham, UK. My supervisor was Deryk Osthus and my co-supervisor was Daniela Kühn. I graduated in July 2015; my thesis was 'Robust Expansion and Hamiltonicity'. Before moving to Birmingham, I did my B.A. and M.Math. at the University of Cambridge from 2007-2011. Here is a copy of my CV.
Research Interests
My research interests lie in extremal combinatorics. During my PhD I mainly worked on Hamilton cycle problems in regular graphs; lately I have been working on stability, supersaturation in graphs and groups, and some problems in combinatorial number theory.
