Welcome!

I am a postdoctoral fellow in the Geometry and Topology Research Group at the Technion -- Israel Institute of Technology working with Michah Sageev. In Fall 2021, I will continue at the Technion as a Zuckerman Fellow.

I received my PhD from Temple University under the supervision of David Futer in May 2020. Here is my CV.

My research interests lie in geometric group theory and low-dimensional topology.

Specifically, I am interested in the interplay between combinatorial and dynamical behavior of group actions such as uniform exponential growth with the algebraic properties like presence of free subgroups. I mostly work with groups possessing one of several notions of nonpositive curvature including: Gromov hyperbolicity CAT(0), relative hyperbolicity, acylindrical hyperbolicity, hierarchical hyperbolicity.


I recently gave a five-minute talk describing some of my research at Aspects of curvature in group theory at CIRM.

Here are the slides I used: Finding free semigroups in nonpositive curvature.
