I am a Lecturer in Statistical Science in the School of Mathematics, University of Bristol.
Here is my CV and here is my research statement. See here for a PhD project on ``Precise Asymptotics in High-Dimensional Statistics using Random Matrix Theory and Statistical Physics''.
Reach me at yihan (dot) zhang (at) bristol (dot) ac (dot) uk or drop by GA.01, Fry Building.
I am in support of slow science. See also reflections by Yoshua Bengio.
Since some people care about it, I may put the (α-β) label to indicate alphabetical author order (see the Hardy--Littlewood rule).
