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 6-8 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. This typically leads to an undergraduate thesis or publishable work. Take a look at some of the research projects.
