Quentin Berthet

Lecturer

Statistical Laboratory,
Department of Pure Mathematics
and Mathetical Statistics

University of Cambridge

I am a Lecturer in the Statslab, in the DPMMS at the University of Cambridge, and a fellow of St John's College. I am also a Turing Fellow at the Alan Turing Institute.

I completed my Ph.D. at Princeton University, under the supervision of Philippe Rigollet. I was also a CMI postdoc at Caltech, hosted by Venkat Chandrasekaran.

My interests are in Statistics, Optimization and Computer Science, and the relationship between computational and statistical efficiency.

I organise the Cambridge Statistics Seminar.
