I moved to the department of mathematics at the University of British Columbia. This webpage will no longer be updated. From 2017 until 2020 I was a research associate in the Statistical Laboratory, part of the DPMMS at the University of Cambridge.
I received my PhD from UC Berkeley, where I was mentored by Allan Sly.
Before coming to Cambridge I was a postdoc at the Faculty of Mathematics at the Weizmann institute of science.
I was an intern in the Microsoft Research Theory Group in the summers of 2014 and 2015, under the mentorship of Yuval Peres.
