I am currently an Assistant Professor at The Ohio State Universty. I received my Ph.D. in 2015 from the Courant Institute at New York University under B. Kleiner. After that I had postdoc positions at McGill University and Max-Planck Institute for Mathematics (Bonn). Here is my CV.

Research Interests: geometric group theory and metric geometry.

I am currently co-organizing Topology and Geometric Group Theory seminar at OSU with Mark Pengitore and Rachel Skipper.
