My research interests include topological and geometric combinatorics, stochastic topology, topological statistical mechanics, and geometric group theory. I am also interested in topological data analysis and applications of algebraic topology in general.

My research has frequently been supported by NSF. I am currently the PI on an NSF-DMS grant on "Stochastic topology and topological statistical mechanics", a TRIPODS+X:RES grant on "Thermodynamic Phases and Configuration Space Topology" (2019–2021), and an RTG grant on "Algebraic Topology and its Applications" (2016–2021)).

Almost all of my mathematical writing is available in preprint form on the arXiv.
