Peter Keevash

Peter Keevash (born 30 November 1978) is a British mathematician, working in combinatorics.

In joint work with Tom Bohman[4] he established the best-known lower bound for the off-diagonal Ramsey Number

(This result was obtained independently at the same time by Fiz Pontiveros, Griffiths and Morris.

[5]) On 15 January 2014, he released a preprint[6] establishing the existence of block designs with arbitrary parameters, provided only that the underlying set is sufficiently large and satisfies certain obviously necessary divisibility conditions.

In 2018, he was an invited speaker at the International Congress of Mathematicians in Rio de Janeiro.
