I am currently a Boya postdoctoral researcher at Beijing International Center for Mathematical Research (BICMR)-Peking University. I received my doctorate at University of Wisconsin-Milwaukee in May 2019 under the guidance of Prof.Chris Hruska.

My research interests are in geometric group theory and low-dimensional topology. In particular, quasi-isometric classification, commensurability classification, and geometric relationship between a group and its subgroups (subgroup distortions, quasiconvexity,...). I spend a lot of time working with 3–manifold groups.

Here is a copy of my CV.
