Research Interests

Under the major headings of "Risk Assessment and Management in Complex Technological and Environmental Systems" and "Multiphase Transport Phenomena”, our 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.
