Seminars

I jointly organised the Warwick combinatorics seminar (Fridays, 14:00, MS.04) for 2017–18, with Katherine Staden (term 1) and with Maryam Sharifzadeh (terms 2–3).

Earlier this year I gave a "speed talk" at BMC in St Andrews in June, and spoke at the Cambridge combinatorics seminar (term 2) and the QMUL combinatorics study group (term 1).


Research

My main research interests are random graphs, preferential attachment, extremal problems on graphs and hypergraphs, and graph searching. I am currently working with Agelos Georgakopoulos on the ERC project Random Graph Geometry and Convergence.
