I am a Professor of Mathematics at the California Institute of Technology, which I joined in fall 2021. Before coming to Caltech, I was a Senior Research Associate and 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. I obtained my PhD in 2017 from the University of British Columbia under the supervision of Asaf Nachmias and Omer Angel.

My research interests lie mostly in discrete probability, with some of my work touching on mathematical physics, group theory, ergodic theory, metric geometry and combinatorics.

I am an organizer of the Percolation Today webinar and an associate editor of Probability Theory and Related Fields and the Annales de l'Institut Henri Poincaré.

I am also an organizer of the Los Angeles Probability Forum, a new monthly event for the LA probability community beginning in 2022.

My ORCiD is 0000-0003-0061-593X. Click here for my CV.
