I am a professor and vice chair for inclusive excellence in the math department at the University of California, Irvine. I’m interested in the interplay of arithmetic, geometry, and topology.

With Jeff Streets, I co-direct the Southern California Geometry and Topology Center, currently supported by an NSF RTG.  We are actively recruiting graduate students with interests in geometry and topology.
