**About Me:**

Prior to arriving at Swarthmore College in Fall 2008, I was an Assistant Professor at Ohio State University, and a VIGRE postdoctoral fellow and Ritt Assistant Professor at Columbia University. I received my Ph.D. in Mathematics from the University of Chicago under the direction of William Fulton, and received my A.B. in Mathematics from Harvard College. 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. I was away from Swarthmore in 2011-13, when I worked at the National Science Foundation as a Program Director in the Topology and Geometric Analysis Programs in the Division of Mathematical Sciences.
