I am an NSF postdoc with Stefan Patrikis at The Ohio State University. My research is currently funded by NSF MSPRF 2503371.

I graduated from University of Wisconsin, Madison in May 2025, where I was advised by Ananth Shankar.

Previously, I did my dual BS-MS from IISER Mohali, India. Here is my CV.

I work in Arithmetic geometry.

My email is bhatnagar.62@osu.edu.
