I am an Assistant Professor in the CSA Department at IISc. I obtained my PhD in Algorithms, Combinatorics, and Optimization (ACO) from School of Computer Science in Georgia Institute of Technology, Atlanta, USA. Before that I got my B. Tech and M. Tech (Dual Degree) from the Department of Computer Science and Engineering, Indian Institute of Technology (IIT), Kharagpur, India. In the past years, I have spent some wonderful time doing research at TU Munich, IDSIA Switzerland, Microsoft Research Redmond, UC Berkeley, Microsoft Research Silicon Valley, TU Eindhoven and IBM Research. You can find my CV here.


Research: I am broadly interested in the design and analysis of algorithms and theoretical computer science. My current research focus is on Approximation Algorithms, Online Algorithms, Online Learning, and Combinatorial Optimization. I am also interested in Computational Geometry, Graph Algorithms, Parameterized Algorithms, and Algorithms for Big Data and Machine Learning.
