I am currently a Visiting Assistant Professor at Cornell University. Before this, I was a Ross Assistant Professor at The Ohio State University and a Visiting Assistant Professor at the University of California, Riverside.
I received my PhD from Vanderbilt University under the supervision of Alexander Ol'shanskii.
My research interests lie in geometric, combinatorial, and algorithmic group theory.
