Research
My research involves moonshine and related aspects of number theory. I'm particularly interested in the question: "Can moonshine help solve problems in number theory?"
Slides for a 5-min lightning talk on my work can be found here. For a quick introduction to moonshine, you can watch this 30-minute talk I gave on the topic.

Elliptic Curves and Thompson's Sporadic Simple group; arXiv version; published version.
Abstract: We characterize all infinite-dimensional graded virtual modules for Thompson’s sporadic simple group, whose graded traces are certain weight 3/2 weakly holomorphic modular forms satisfying special properties. We then use these modules to detect the non-triviality of Mordell--Weil, Selmer, and Tate--Shafarevich groups of quadratic twists of certain elliptic curves.

In Preparation.
Abstract: The Monster Lie algebra m is a quotient of the physical space of the vertex operator algebra V:=V^\natural \otimes V_{I,I}. We construct families of elements that generate gl 2-subalgebras of V corresponding to imaginary simple roots of m. We prove the existence of primary vectors in V^\natural of each homogeneous weight and for 0<n<100, we show that these can be used to construct the corresponding gl 2-subalgebras. Furthermore, we show that the Monster acts non-trivially on each of these subalgebras and that this induces an action on their image in m.
