**About Me:**

Prior to arriving at Swarthmore College in Fall 2008, I was an Assistant Professor at Ohio State University from 2004 to 2008, and a VIGRE postdoctoral fellow and Ritt Assistant Professor at Columbia University from 2000 to 2004. I received my Ph.D. in Mathematics from the University of Chicago in June 2000, under the direction of William Fulton, and received my A.B. in Mathematics from Harvard College in June 1996. I grew up mostly in Ann Arbor, Michigan, but was born in upstate New York, and lived in New York City and New Jersey before moving to Michigan. During academic years 2011-13, I worked at the National Science Foundation as a Program Director in Topology and Geometric Analysis in the Division of Mathematical Sciences.
