As of 2017, I'm working in Sanjit Seshia's research group. My work focuses on algorithmic improvisation, as well as the theory and applications of model counting and uniform generation.

Older Work

In the summer of 2012 I did a UROP, advised by Henry Cohn. The original topic was the computability of Newton fractals, but my research took a tangent into reachability under affine functions on the integers and related problems. I talked about my work at the RP12 workshop - you can find my slides here. A writeup of my results is available on the arXiv.

In the spring of 2012 I did a UROP with Shankar Raman on the history of notions of continuity and the infinite in mathematics and philosophy. My research was mostly on Cavalieri's theory of indivisibles, Leibniz's various theories on the composition of the continuum, and the early development of set theory.

In the summer of 2011 I did a UROP on tetrahedral numbers, advised by Abhinav Kumar. Most of my time was spent learning about the circle method, which unfortunately seems unlikely to be of much use in proving Pollock's conjecture that every positive integer is the sum of at most 5 tetrahedral numbers. The current best result, by G. L. Watson in 1952 (Sums of eight values of a cubic polynomial, in J. London Math. Soc.) using an ad hoc method, is that 8 tetrahedral numbers suffice.
