**Riemann Surfaces and Their Moduli Spaces.** My interest here
lies in studying the maps between Hurwitz spaces (which are spaces of branched
coverings of the Riemann sphere sharing a common combinatorial description)
and moduli spaces. I am also interested in the geometry and topology of
the moduli spaces themselves, and in certain aspects of the uniformization
problem.

**Computer Visualization.** In recent joint work with Anuj
Srivastava, Washington Mio and others, we are applying ideas from differential
geometry to problems in computer visualization.
