Ph.D., MIT, 2007. Thesis title: "A Verification Framework for Hybrid Systems." Advisor: Nancy Lynch
Sayan graduated from MIT in 2007 and spent one year as a post-doctoral researcher at the Center for Mathematics of Information of CalTech. Earlier, he completed MSc from the Indian Institute of Science, Bangalore and undergraduate degree in EE from Jadavpur University, Kolkata. He received the National Science Foundation's CAREER award in 2011, AFOSR Young Investigator Research Program Award in 2012. His research is aimed at developing algorithmic techniques for analyzing (and finding defects) in complex software systems that interact with physical processes.

The goal our research is to develop algorithms and software tools that enable the creation of reliable computing systems. Typical application domains include autonomous vehicles, traffic control systems, medical devices, control systems etc.
Graduate Research Opportunities
We are looking for graduate students with background in CS theory (formal methods, logic, automata theory, algorithms) and/or control theory. Solid programming skills & other mathematical background (e.g. stochastic processes) would be a plus. As an graduate researcher you will develop new verification and synthesis algorithms, build tools, and perform experiments in using these tools on real systems.
Undergraduate Research Opportunities
We are looking for juniors/seniors with solid programming skills (E.g., C/C++, Java, Matlab) and who intend to go to grad school in one of the related research areas. Preference will be given to those who can commit to working at least 4-5 hours a week for a couple of semesters. You will work closely with one of the graduate students towards developing software tools or applying them to verify a systems. Take a look at some of the research projects.
