I'm an Assistant Professor of Mathematics at the City University of New York (City Tech). I obtained my doctorate at the University of Oxford, under the supervision of Peter M. Neumann, and my undergraduate degree at Imperial College London. From 2010 until 2012 I held a Philip T. Church Postdoctoral Fellowship at Syracuse University, and in 2013 I was awarded an Early Career Researcher Award (DECRA) by the Australian Research Council.

My research lies in the intersection of group theory, combinatorics and topological group theory. I'm particularly interested in infinite permutation groups which act on locally-finite graphs, and totally disconnected locally compact topological groups. A list of my publications can be found on this website.

My academic family tree can be found in the Mathematics Genealogy Project.

For four years immediately after my doctorate I worked first as a mathematician (called a "quant"), and then as a derivatives trader, at a major European investment bank. While there I conducted original research into the mathematical modeling of interest rate derivatives, stochastic calculus and perturbation methods. I would like to reassure readers that I did not cause the Credit Crunch.
