Research Description

"Risk Assessment and Management in Complex Technological and Environmental Systems" and "Multiphase Transport Phenomena”, from basic aspects, such as methodological issues in treating uncertainty in risk assessment, and basic multiphase flow physics, such as interfacial instabilities, to integrative and synthetic efforts towards understanding and optimizing real system behavior, assessing risks, and improving safety. Current projects: interfacial instabilities in high speed flows, aero-breakup, explosive dissemination of liquids, homeland security, defense against chem-bio weapons, burnout physics, nuclear reactor safety.

Biography

Theofanis (Theo) G. Theofanous is professor in the Chemical Engineering and Mechanical Engineering Departments at UCSB, and Founding Director of the Center for Risk Studies and Safety (CRSS). He is a graduate of the National Technical University of Athens, Greece, and holds a PhD from the University of Minnesota, both in Chemical Engineering. Prior to coming to UCSB in 1985, he taught at Purdue’s Chemical Engineering and Nuclear Engineering Departments, where he was also the Founding Director of the Nuclear Reactor Safety Laboratory. Under the major headings of "Multiphase Transport Phenomena” and "Risk Assessment and Management in Complex Technological and Environmental Systems" his interests and work range from basic aspects, such as methodological issues in treating uncertainty in risk assessment, and basic multiphase flow physics, such as interfacial instabilities, to integrative and synthetic efforts towards understanding and optimizing real system behavior, assessing risks, and improving safety. Current key words: interfacial instabilities in high speed flows, aero-breakup, explosive dissemination of liquids, homeland security, defense against chem-bio weapons, burnout physics, nuclear reactor safety. He is a member of the National Academy of Engineering, a fellow of the American Nuclear Society, and he is holding an Honorary Doctorate from the University of Lappeenranta in Finland. In 1997 he received the E. O. Lawrence Medal from the US Department of Energy for his work on managing risks of Severe Accidents in Nuclear Power Reactors.
