I am a Professor at the University of Cambridge and a Fellow at Trinity Hall. I was formerly a Clay Research Fellow.
My work currently receives funding from the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation programme (grant agreement No 714405).

Together with Beth Romano, I organize the Number Theory seminar at Cambridge. You can view the list of upcoming talks for the seminar here, and subscribe to the seminar mailing list here.
