I study symplectic geometry and its relationships with combinatorics, algebraic topology, and algebraic geometry. Recent projects include: (1) investigating origami structures: structures which are nearly but not quite symplectic; (2) exploring the topology of symplectic quotients that are orbifolds; and (3) computing symplectic invariants such as the Gromov width.
