Research

My interests are in enumerative, algebraic, and dynamical combinatorics. I wrote my dissertation about a specific function called the stack-sorting map. A lot of my recent work has focused on other combinatorial dynamical systems, many of which are defined in Coxeter-theoretic or lattice-theoretic settings. While most of the research in dynamical algebraic combinatorics focuses on invertible maps, I have spent a lot of time thinking about maps that are very much noninvertible.

My curriculum vitae contains a (usually) up-to-date list of my publications and preprints, all of which are available on arXiv. You can also read my research statement, which I prepared for postdoc and fellowship applications.
