Scholarship
My research is in the general area of Number Theory. I obtained my Ph.D. in 2009 at the University of Texas at Austin under the direction of Fernando Rodriguez-Villegas, and the title of my thesis was “Hypergeometric Functions in Arithmetic Geometry.” I am working on several projects at the moment: in the theory of formal multizeta values, arithmetic dynamics, arithmetic mirror symmetry, and mathematical origami.
I am a proud member of the Women in Number Theory group, and you will notice that many of the publications listed below are closely tied with this wonderful research community.
