Northwestern University, Evanston (Chicago)
I am an Assistant Professor at Northwestern University. I graduated with a BSc in Mathematics and Computer Science from Chennai Mathematical Institute in August, 2012. I was a PhD student at Harvard University under the supervision of Mark Kisin, and graduated in May 2017. Before joining Northwestern, I was at MIT as a CLE Moore Instructor until July 2020, and an Assistant Professor at UW Madison until June 2023. Here is my CV.
My research is in arithmetic geometry and number theory. More specifically, I work in the following areas:
Arithmetic aspects of Shimura varieties.
The Grothendieck-Katz p-curvature conjecture.
Here are some of my research papers:
A p-adic analogue of Borel's theorem.
With A. Oswal and X. Zhu, and an appendix by A. Patel.
Just-likely intersections on Hilbert modular surfaces.
With Asvin G. and Q. He, submitted.
Canonical Heights on Shimura Varieties and the André-Oort Conjecture
With J. Pila and J. Tsimerman, and an appendix by H. Esnault and M. Groechenig, submitted.

Together with Yuchen Liu and Jihao Liu, I'm organizing the Northwestern Algebraic Geometry seminar.
Along with Jordan Ellenberg, Wanlin Li and Ziquan Yang, I have organized a conference "Arithmetic and Topology over Global Fields".
I am a co-organizer of an online seminar series, New Developments in Number Theory, an series aimed at early career number theorists.
