Current Events

This semester I'm teaching Math 246 (Probability).

I attend the Valley Geometry Seminar and the Representation Theory seminar regularly.

Other events:

- In October, I'll attend a Springer theory conference at UMass.
- In November, I'll speak at an AMS special session in Rutgers.
- In January, I'll speak at an Association for Women in Mathematics workshop on algebraic combinatorics at the Joint Meetings in Seattle.

Research Interests and Activities

My research is in algebraic geometry where it intersects combinatorics and representation theory. I use combinatorial or algebraic tools to answer geometric questions, and vice versa. I am supported by a National Science Foundation grant and was an Alfred P. Sloan fellow.

A **geometer** studies objects like circles, spheres, doughnuts, inner tubes, and others too complicated to imagine. The most concise way to describe geometric objects is as the zero set of a collection of polynomials; for instance, the zero set of x^{2}+y^{2}=1 is the unit circle in the plane. Now imagine the zero set of seventeen polynomials in forty variables. What dimension is it? Does it have holes? How many pieces does it have? An **algebraic** geometer uses the algebra of polynomials to answer questions like these about the object.
