about me

I am an Associate Professor of Computer Science at Duke University. Before coming to Duke in 2013, I spent one year as a postdoctoral research in the theory group at Microsoft Research Redmond, where I did research in algorithms. In 2012, I obtained my PhD in theoretical computer science at MIT under the supervision of Prof. David Karger by defending this. Before coming to MIT, I worked at Bell Labs in Bangalore for a year, where I did research on algorithms and networks. I obtained my bachelors' and masters' degrees in Computer Science and Engineering at Jadavpur University, Kolkata in 2004 and IISc, Bangalore in 2006 respectively. At IISc, I did research in algorithms under the supervision of Prof. Ramesh Hariharan. A long time ago, I grew up in the industrial town of Durgapur where I went to St. Xavier's School.

My CV is available here.

Research Interests

My research is in Theoretical Computer Science, focusing on the Design and Analysis of Algorithms with provable properties. Specific topics of interest include:

  • Graph Algorithms, particularly the study of Cuts, Flows, and Connectivity in graphs.

  • Algorithms under Uncertainty, particularly Online Algorithms.

  • Theoretical Machine Learning, particularly its role in Beyond Worst-Case algorithm design.

  • Approximation Algorithms for Combinatorial Optimization of NP-hard problems.

  • Algorithms in the Real World, including algorithms for Online Search, Advertising, and E-commerce, in Computer, Social, and Information Networks, in Computational Economics, in Big Data environments and Database Systems, etc.

I am generally excited by any algorithms research problem, but for a sample of my current research directions, see here.

I am part of the theory group and am also affiliated/collaborate with the CS-econ, AI/ML, and database groups at Duke.

teaching

I have taught various courses in algorithms and theoretical computer science at the graduate and undergraduate levels.

Current Course

Spring 2021. COMPSCI 330 Design and Analysis of Algorithms (undergraduate course in algorithms, will be co-taught with Prof. Rong Ge)

Spring 2021. COMPSCI 590.04 Special Topics in Computer Science: Machine Learning Algorithms (graduate course on "algorithms for ML" and "ML-augmented algorithms", will be co-taught with Prof. Rong Ge)

Upcoming Course

Fall 2021. COMPSCI 290 Special Topics: Great Ideas in Computer Science (an introduction to computer science from the perspective of the big ideas, conflicts, and questions that computer science has brought to the fore: the course will include discussions on the historical perspective of the emergence of computer science and its meteoric rise in less than a century, how computer science relates to mathematics, engineering, and other branches of science, the role of computer science in shaping human thought and knowledge in a modern world, and some of the big futuristic questions that computer science faces today in theory and practice)
