Prospective Students: I am looking for motivated Ph.D students with an interest in data science and basic proficiency in theoretical computer science and algorithms. If you want to enjoy five years solving cool and interesting algorithmic problems, send me an email, and check out the graduate program at CUNY Graduate Center.

Short Bio: I received my Ph.D. from the Applied Mathematics and Statistics at the Stony Brook University, New York. My advisors were Joe Mitchell and David Gu. From 2013-2016 I was a researcher at the Max-Planck Institute for Informatics in Germany, in the Algorithms and Complexity group headed by Kurt Mehlhorn. I received my Bachelors in Mathematics (B.Math.) from the Indian Statistical Institute, Bangalore, India.

Research Interests:

- Algorithms - sorting, searching, binary search trees, succinct data structures and variants of Bloom filters, graph problems, I/O efficient algorithms, lower bounds.
- Computational geometry and algorithms for geometric databases.
- Theoretical machine learning - removing noisy labels, generalization performance.
- Conformal geometry, Teichmuller theory, and harmonic measure.

I hosted the Fall Workshop on Computational Geometry (FWCG) in October 2018. Here is the webpage.

I organize the Computer Science Seminar, Q4C (Queens College CS Colloquium)
