My primary research area is number theory, including arithmetic geometry and automorphic representation theory. (Show/Hide Research Summary).
I study Siegel modular forms, automorphic representations of $\GSp(4)$, and abelian surfaces. My work is motivated by several theorems in the case of elliptic curves and elliptic modular forms that are conjectured to generalize to genus two. In particular, I am interested in the paramodular conjecture and the equivariant Tamagawa number conjecture. The paramodular conjecture states that every simple abelian surface which is not of $\GL(2)$-type is paramodular in the sense that if $N$ is the conductor of the abelian surface, then there is a Siegel modular form of paramodular level $N$. The equivariant Tamagawa number conjecture on special values of $L$-functions unifies and generalizes the Dedekind class number formula, the generalized Stark's conjectures, and the Birch and Swinnerton-Dyer conjecture.

In addition, I spend some time thinking about Math Education(Show/Hide MathEd Summary).
As a Co-PI on the Making Mathematical Reasoning Explicit MSP grant, I had the opportunity to work with teachers of 4th through 12th grade to develop methods and activities that encourage active learning while giving access to learners at various levels. I am working to apply what I have learned through working with teachers to my classrooms at the graduate and undergraduate level.
This fall, I will be giving a presentation at the UI Advising Symposium on September 11, 2015 on the topic of "Perserverance in Problem Solving."
If you are interested in doing research with me or need a letter of recommendation, please come to my office hours or send me an email to set up an appointment.

I have been an Assistant Professor in the Department of Mathematics at the University of Idaho since 2007. Prior to joining the faculty at Idaho, I was an instructor at Brandeis University for 2 years. I received my PhD in 2005 from Caltech under the direction of Matthias Flach. I am also an alumna of The College of William and Mary (1998). I enjoy working and playing in Moscow, Idaho with my husband and four children.
