Welcome to the homepage of the Theoretical Computer Science Group at the Department of Computer Science and Engineering, Indian Institute of Technology Madras, Chennai, India. We are a group of faculty, postdocs, graduate students and undergraduate students at CSE Department of IIT Madras who work mainly in the area of theoretical computer science.

The group was founded in the 1980s and physically formed the theoretical computer science lab (fondly called TCS Lab) in 1991. Now the members are distributed across two lab spaces - the Theoretical Computer Science (TCS) Lab and the Algorithms and Complexity Theory (ACT) Lab.

Please refer to the department webpage for information regarding joining (the CSE department) as a graduate student, or as a postdoc or young international faculty, or as a regular faculty member.
