Assistant.Professor
Department of Mathematics and Statistics
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.
Upcoming.Events
- Thursdays, 4:00-5:00pm: I am co-organizing the Philadelphia Combinatorics and Algebraic Geometry (CAGE) Seminar, held at the University of Pennsylvania, along with Jim Haglund (UPenn) and Jennifer Morse (Drexel).
- March 23-27, 2009: I am co-organizing the Combinatorial, Enumerative, and Toric Geometry Workshop at MSRI in Berkeley (see also list of speakers and other information). It is part of the Jumbo Year in Algebraic Geometry , January 12 - May 22, 2009.
- January 22-24, 2009: I am a Plenary Speaker for the Connections: Algebraic Geometry and Related Fields Workshop (see also the schedule) which opens the Jumbo Year in Algebraic Geometry at MSRI in Berkeley.
Research.Interests
Algebraic geometry and algebraic combinatorics. Some of my work involves Schubert calculus, quot schemes, Fulton-MacPherson spaces, the moduli space of curves and its generalizations, quantum cohomology, toric varieties, Hilbert schemes of points on surfaces, equivariant cohomology and GKM spaces, orbifold cohomology and Gromov-Witten theory of stacks, Hessenberg varieties, affine Grassmannians, and other aspects of enumerative and combinatorial geometry.Some.Collaborators
L. Borisov (Rutgers), C. Cadman (UBC), T. Braden (U Mass Amherst), A. Gibney (Georgia and UPenn), D. Krashen (Georgia), T. Nevins (UIUC), G. Smith (Queen's), F. Sottile (Texas A & M), J. Tymoczko (Iowa).Mailing.Address
