Jonathan Hermon

I am an assistant professor at the mathematics department at the University of British Columbia. 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, where I was mentored by Itai Benjamini, who was also my Master's advisor.

Research interests

  • My research is in discrete probability theory with a special emphasis on problems related to the theory of mixing times of Markov chains and the cutoff phenomenon. I am also working on particle systems and percolation. A common theme of my work is the study of Markov chains, particle system models and other statistical mechanics models on general graphs, or on large families of graphs, using some very "discrete probability" arguments, combined with some analysis.
