CV

I am an Assistant Professor at Boston University. I am interested in algebraic geometry and number theory. My research is supported by NSF DMS 2401547.

Previously I was a Senior Research Scientist at ICERM with the Simons Collaboration on Arithmetic Geometry, Number Theory, and Computation, a Limited Term Assistant Professor at the University of Georgia and a Hale Visiting Assistant Professor at Georgia Institute of Technology. I received my PhD in 2016 at MIT under the supervision of Bjorn Poonen. My undergraduate and masters degrees are from Chennai Mathematical Institute.

I mentor PhD student Matt Broe.

Courses and seminars

I help organize the BU Arithmetic Geometry seminar, and the BU Number Theory learning seminar. The topic of the learning seminar in Spring 2026 is the Categorical Langlands Conjecture.

I am currently teaching MA 746: Topics in the arithmetic and geometry of curves.

I help organize the PAWS: Preliminary Arizona Winter School. The topics for Fall 2025 are Mathematical cryptography and algorithms in number theory. The topic of the AWS: Arizona Winter school in Spring 2026 is Computational Aspects of Arithmetic Geometry and Cryptography.
