I am a fourth-year Ph.D. student at the mathematics department at the University of California San Diego working with Prof. Dragos Oprea. I graduated from the Indian Institue of Science with a bachelor's degree in Mathematics in 2017. Here is my CV.

I am interested in enumerative problems in Algebraic geometry, such as Moduli spaces parameterizing vector sub-bundles and Gromov-Witten Invariants. I am also interested in problems in Algebraic combinatorics.

(1) **The size of t-cores and hook lengths of random cells in random partitions.**[arXiv]

(with Arvind Ayyer) : Fix $t \geq 2$. We first give an asymptotic formula for certain sums of the number of $t$-cores.
We then use this result to compute the distribution of the size of the $t$-core of a uniformly random partition of an integer $n$.
We show that this converges weakly to a gamma distribution after dividing by $\sqrt{n}$. As a consequence, we find that the size of the $t$-core is of the order of $\sqrt{n}$ in expectation. We then apply this result to show that the probability that $t$ divides the hook length of a uniformly random cell in a uniformly random partition equals $1/t$ in the limit. Finally, we extend this result to all modulo classes of $t$ using abacus representations for cores and quotients.

Olympiad : I was involved in training Indian IMO (International Mathematical Olympiad) team during the years 2014-2017.

Mentoring at UCSD : I mentored a group of undergraduate students at UCSD, in Spring 2020, as part of UCSD's RTG grant. We discussed basics of algebraic geometry and classical theorem : '27 lines on a cubic surface'.

I am a TA for the gradutae course Complex Analysis (Math 220B) and Discrete Math & Graph Theory (Math 154).
