My research interests lie primarily in geometric group theory, combinatorics, and topology, with a particular interest in the braid group and its relatives. Some of my recent work has focused on the geometric and combinatorial connections between braids, complex polynomials, and noncrossing partitions. My other interests include Coxeter groups, Artin groups, mapping class groups, and configuration spaces.
