Research Interests


If it involves complex hyperbolic geometry in any way, I'm probably interested in it. Specifically, my research is focused around discrete subgroups of complex hyperbolic isometries, and in particular lattices (both arithmetic and non-). I'm interested in finding techniques analogous to "hybridization" (a process produced by Gromov and Piatetski-Shapiro for real hyperbolic lattices) to allow for the construction of new commensurability classes of lattices in PU(n,1).
Lately, I've also taken an interest in the embedding of hyperbolic 3-manifolds into the boundary of complex hyperbolic 2-space. Such embeddings help to provide answers to the following question about geometric transitions: "Which hyperbolic 3-manifolds can be endowed with a (uniformized) spherical CR structure?"
