I am a Herchel Smith Postdoctoral Research Fellow in the Department of Pure Mathematics and Mathematical Statistics at the University of Cambridge and a Junior Research Fellow in Trinity College. Previously, I obtained my PhD in the probability group in the University of British Columbia in Vancouver under the supervision of Asaf Nachmias and Omer Angel. Before that, I completed my BA and MMath at King's College, Cambridge.

I was an intern in the Microsoft Research Theory Group in the summers of 2015, 2016, and 2017, and was supported during my PhD by a Microsoft Research PhD Fellowship.

I plan to go on the job market in the second half of 2020. Click here for my CV.
