Michael Savery

I am studying for a DPhil (PhD) in Mathematics at the University of Oxford under the supervision of Alex Scott. I work in combinatorics, more specifically extremal and probabilistic combinatorics. Before coming to Oxford I completed four years of undergraduate study in mathematics at Queens' College, Cambridge.
