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

Short Bio: I received my Ph.D. from the Applied Mathematics and Statistics at the Stony Brook University, New York (CGPA: 3.99/4). 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.

If you are are a prospective student who wants to enjoy five years solving cool and interesting algorithmic problems (in New York City), send me an email, and check out the graduate program at CUNY Graduate Center.

Research Interests

I am interested in algorithms and mathematical techniques for handling large sets of data that are either 1) centralized, 2) distributed or 3) visual.

  • Centralized data sets -- Approximate and adaptive data structures for databases and the external memory (Disk Access Model) setting. Apart from developing practical and efficient data structures, I also enjoy proving lower bounds on problems arising in these domains.

  • Distributed data sets -- Networks and distributed algorithms for sensor networks and social networks. The main problems I have studied here are distributed load balancing in wireless networks, secure communication protocols, efficient data aggregation via mobile agents and very recently, the topology of social networks. Main tools here are combinatorics, graph theory and optimization.

  • Visual data sets -- Computer Graphics and Vision: Computation in shape spaces (moduli or Teichmuller spaces) and applications to computer vision. Most of my work here is motivated by surface registration and matching problems and uses techniques from classical mathematics (differential, complex and algebraic geometry).

    • I publish in both theory and applied fields, in conferences ranging from (FOCS, SODA, SoCG, ESA) to (ICML, INFOCOM, ICCV, IPSN, MobiHoc). If you want to discuss any problems (possibly, but not necessarily, relating to my publications below), feel free to drop me an email.
