About Me

I am an Assistant Professor in the Department of Computer Science at Virginia Tech. Prior to joining Virginia Tech, I spent two years as a postdoc in the Computer Science and Management Science and Engineering departments at Stanford working with Prof. Leo Guibas and Prof. Ashish Goel. I completed my Ph.D. from the Department of Computer Science at Duke University where I worked with Prof. Pankaj Agarwal. I received my B. Tech (Hons) (Computer Science) from IIIT, Hyderabad.

 

Research Interests

My research interests is in the domain of computational geometry. In particular, I am interested in design of algorithms for large-scale, unstructured and potentially high-dimensional geometric data.

I am also interested in design of approximation algorithms that solve optimization problems over large scale inputs. In my Ph.D. thesis titled Geometric Approximation Algorithms - A Summary Based Approach , I designed efficient approximation algorithms for fundamental geometric optimization problems using a summary based approach, i.e., quickly compute a compact representation (or summary) of the input and extract an approximately optimal solution from this summary by a relatively slower algorithm. My dissertation won the Duke Computer Science Outstanding Ph.D. dissertation for 2012.
