Stochastic hybrid systems: Challenges and opportunities

Hybrid systems, that is systems involving the interaction of discrete and continuous dynamics, have been a very active research area for the past 10 years. Much of the interest in this area has been fueled by the role hybrid systems play in embedded computation and control systems, which, by their nature, involve the interaction of digital devices with an analog environment. Recently, the observation that, in addition to continuous and discrete dynamics, many embedded system applications also involve substantial levels of uncertainty has led to the study of the more general class of stochastic hybrid systems, hybrid systems that also involve probabilistic uncertainty. In this presentation we will survey some of the issues and results in modeling and reachability analysis for stochastic hybrid systems. The discussion will be motivated by problems in collision avoidance in air traffic management and in the modeling of DNA replication in the cell cycle.

Biographical Sketch:
John Lygeros completed a B.Eng. degree in Electrical Engineering in 1990 and an M.Sc. degree in Control in 1991, both at Imperial College, London. He then obtained a Ph.D. in 1996, from the Electrical Engineering and Computer Sciences department, University of California, Berkeley. He held a series of postdoctoral research appointments at the National Automated Highway Systems Consortium, Laboratory for Computer Science at M.I.T., and U.C. Berkeley. In parallel, he also worked as a part time Research Engineer at SRI International, Menlo Park, California, and as a visiting professor at the Mathematics Department of the Universite de Bretagne Occidentale, France. Between July 2000 and March 2003 he was a University Lecturer at the Department of Engineering, University of Cambridge, Cambridge U.K. Since March 2003 he has been an Assistant Professor at the Department of Electrical and Computer Engineering, University of Patras, Patras, Greece. His research interests include modeling, analysis and control of hierarchical, hybrid and stochastic systems, with applications to complex systems such as automated highways, air traffic management, and biochemical networks.
