  • The Physics of Foams (G)
  • Turning up the Heat on Effective Temperatures (S)

Doug Durian is a professor of physics at the University of California, Los Angeles. His general research interests are in the area of "soft" condensed matter physics: the structure, dynamics and macroscopic behavior of a very broad and general class of materials that are typically noncrystalline and composed of macromolecules such as polymers, liquid crystals, surfactants or biomolecules. This growing field complements solid state and statistical physics, and has considerable overlap with disciplines of chemistry, chemical engineering, materials science and even biology. A common theme in soft condensed matter is that while the materials are disordered at the molecular scale and homogeneous at the macroscopic scale, they usually possess a certain amount of order at an intermediate, or mesoscopic, scale due to a delicate balance of interaction and thermal effects. The general goal is to determine this structure and its dynamics, how it arises and how it influences the macroscopic behavior.

Gregory Robinson was educated in Alabama, receiving his B.S. from Jacksonville State University and his Ph.D. from the University of Alabama. Before joining the University of Georgia faculty in 1995, he was a professor at Clemson University. He was an Alexander von Humboldt Research Fellow at the Technische Universitat Berlin in 1994. His research interests concern the organometallic chemistry of the main group elements. Historically somewhat overshadowed by the organometallic chemistry of the transition metals, the organometallic chemistry of the main group elements is now experiencing great activity. In large part this is driven by the quest for single source molecular precursors for advanced inorganic/electronic materials. His research group has developed new synthetic strategies resulting in the preparation of a number of interesting gallium-phosphorus compounds, phosphinogallanes, and indium-phosphorus compounds, phosphinoindanes, which have been shown to be attractive molecular precursor templates.

  • Life in the Age of Risk Management (P or G)
  • Risk Management and Communication Meet Uncertainty and Variability (S or G)
  • Managing Children's Risks: It Takes a Commitment (G)

Dr. Kimberly Thompson is Associate Professor of Risk Analysis and Decision Science at the Harvard School of Public Health, where she created and directs the Kids Risk Project. Professor Thompson is a nationally and internationally known as an expert on children's risks and on probabilistic risk analysis. Her research interests and teaching focus on the issues related to developing and applying quantitative methods for risk assessment and risk management, and consideration of the public policy implications and communication challenges associated with including uncertainty and variability in risk characterization. Drawing on a diverse background, she seeks to effectively integrate technological, social, political, legal, and economic issues into risk analyses that inform public policy and improve decision making in what she calls the Age of Risk Management ( A popular and engaging speaker, Professor Thompson talks about the serious topic of "Life in the Age of Risk Management" using humor and real life examples that are relevant to broad audiences. She demonstrates the hazards of failing to consider the real differences between individuals that matter when making public policy decisions, and she talks about how to become empowered by uncertainty, instead of paralyzed by it. As director of the Kids Risk Project (, Dr. Thompson is a leading authority on the risks to children and the need for better information to improve decisions made by kids, parents, policy makers, and others. Professor Thompson is co-Founder and Director of Research of the Center for Media and Child Health at the Children's Hospital in Boston, and she performs active research on the messages in popular media (e.g., motion pictures and video games). Dr. Thompson earned her Doctor of Science Degree in Environmental Health at Harvard and her Bachelor and Master of Science Degrees in Chemical Engineering from M.I.T. She is author of Humor in the Age of Risk Management (AORM, 2003) and Overkill: How Our Nation's Abuse of Antibiotics and Other Germ Killers Is Hurting Your Health and What You Can Do About It (with Debra Bruce, Rodale, 2002), and her work has been widely covered in popular media.

Martin Wachs is director of the Institute of Transportation Studies at the University of California, Berkeley, where he is the Roy W. Carlson Distinguished Professor of Civil & Environmental Engineering and professor of city and regional planning. He earlier spent 25 years at UCLA, where he served three terms as chairman of the department of Urban Planning. Wachs is the author of 150 articles and four books on subjects related to relationships between transportation, land use, and air quality, transportation needs of the elderly, techniques for the evaluation of transportation systems and the use of performance measurement in transportation planning. His research also addresses issues of equity in transportation policy, problems of crime in public transit systems, and the response of transportation systems to natural disasters including earthquakes. His most recent work focuses on transportation finance in relation to planning and policy. Wachs has served on the Executive Committee of the Transportation Research Board for nine years and was the TRB chairman during the year 2000.

Martha Zúñiga received a B.A. from the University of Texas at Austin and M.Phil. and Ph.D. degrees from Yale University and postdoctoral training at the Yale University School of Medicine and at Caltech. Presently she is professor of molecular, cell, and developmental biology at the University of California, Santa Cruz. Her research focuses on the role of the structure expression of class I major histocompatibility molecules and its tissue-specific in regulating immune responsiveness versus tolerance. Current research projects are directed at elucidating mechanisms by which immunological tolerance is established and maintained and how virally infected cells and cancer cells subvert otherwise protective immune responses. Zúñiga was a recipient of the Presidential Young Investigator Award in 1989. Other lectures available.
