Current Events

This semester I'm teaching Math 246 (Probability), Math 300 (Dialogues in Math), and Math 301 (Topics in Math).

I co-organize the Algebra/Combinatorics/Geometry seminar at Smith College.

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

Other events:

- In September, I'll speak at a special session at the AMS Sectional Meeting at Bowdoin College, and organize another special session at the same Sectional Meeting.
- In September, I'm also helping organize WIMIN and SMATH at Smith.
- In October, I'll attend a national conference for chairs of math/stats departments in Washington, DC.
- In October, I'll speak at a special session at the AMS Sectional Meeting in the Twin Cities.
- In November, I'm organizing the Connections for Women at AGNES here at the Five Colleges.
- In December, I'm attending a conference at the Fields Institute.

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.
