About Me: I am currently an NSF Postdoctoral Fellow at Columbia University. Last year I was a NSF Postdoctoral Fellow at UC Berkeley, and the previous year I was a Morrey Visiting Assistant Professor, also at UC Berkeley. I received my Ph.D. from the University of Wisconsin-Madison in 2017, where I studied geometric group theory under the supervision of Tullia Dymarz.
Here is a copy of my CV (updated November 2019).
Research interests: I study geometric group theory and low-dimensional topology. In particular, I am interested in group actions by isometries on hyperbolic spaces, especially acylindrical actions. The kinds of groups I think about include hyperbolic and relatively hyperbolic groups, mapping class groups, Out(F_n), CAT(0) groups, three manifold groups, hierarchically hyperbolic groups, and many more.
