I am a Limited Term Assistant Professor at the University of Georgia. I am interested in algebraic geometry and number theory. Previously I was 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.

Here is my CV.
