About me:

I am a Ritt Assistant Professor at Columbia University. My research interests are in algebraic geometry and number theory. I received my PhD in 2019 from Princeton University under the supervision of János Kollár. Previously, I completed my Bachelor's and Master's studies at Chennai Mathematical Institute, India.

Here is my Curriculum Vitae .


My research work is in birational geometry and its applications to number theory, in particular the minimal model program (MMP), rational points on Fano varieties (Manin's conjecture) and the geometry of rational curves. Previously, I worked on higher rank Brill-Noether theory for curves.

Here are some of my papers:

1. Geometric consistency of Manin’s Conjecture (with B. Lehmann and S. Tanimoto ) To appear in Compositio Mathematica (2022). arXiv:1805.10580.
2. Manin’s Conjecture and the Fujita invariant of finite covers. Algebra & Number Theory (2021). arXiv:1712.07780.
3. Manin’s b-constant in families. Algebra & Number Theory 13(8): 1893-1905 (2019). arXiv:1708.05447.
4. Counterexamples to Mercat’s conjecture, Archiv der Mathematik 106, 439-444 (2016) arXiv:1306.2553.
