Research Interests :
Algebraic geometry and algebraic combinatorics, including quantum cohomology, K-theory, equivariant cohomology, Schubert calculus, degeneracy loci, moduli spaces of curves, affine Grassmannians, and other aspects of enumerative and combinatorial geometry.
I co-organize the annual Mid-Atlantic Algebraic Geometry and Combinatorics (MAAGC) Workshop, funded by NSF conference grant DMS-1728937.
I co-organize the Philadelphia Combinatorics, Algebra, and Geometry (CAGE) Seminar, held at the University of Pennsylvania/Drexel University.
I organize the Swarthmore Math/Stat Colloquium.
The Math-Physics Joint Seminar is held at the University of Pennsylvania.
Current and Upcoming Activity:
As of February 2022, I am the Associate Treasurer of the American Mathematical Society, and am a member of the Board of Trustees and Council of the AMS,.
I was a keynote speaker for the Annual Graduate Student Conference in Algebra, Geometry, and Topology (GTA Philadelphia) in May 2022.
I was elected to the Executive Committee of the Association for Women in Mathematics and served 2020-2022.
I am an Associate Editor for The American Mathematical Monthly.
I served on the Prize Committee for the American Mathematical Society (AMS) Mary P. Dolciani Prize for Excellence in Research, 2018-2022.
I was a group leader for the Women in Algebraic Geometry Collaborative Research Workshop at the Institute for Computational and Experimental Research in Mathematics (ICERM), July 27-31, 2020.
Selected Past Activity:
I was elected to a three-year term on the American Mathematical Society (AMS) Nominating Committee and served 2017-2019. I was on the AMS Committee on Academic Freedom, Tenure, and Employment Security in 2016-2018.
I was a speaker in the Facets of Algebraic Geometry conference in October 2019.
I was a plenary speaker for the MAA NJ Section Meeting in October 2018.
I was a speaker in the Western Algebraic Geometry Symposium in March 2018 .
I was a speaker in the Georgia Algebraic Geometry Symposium in February 2018.
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.
