COMMITTEE MEMBERS

Thorne Lay (Chair) is distinguished professor of earth and planetary sciences at the University of California, Santa Cruz, where he was founding director of the Institute of Geophysics and Planetary Physics and is currently director of the Center for the Study of Imaging and Dynamics of the Earth. His primary research interests involve analysis of seismic waves to interrogate the deep structure of Earth’s interior and to study the physics of earthquake faulting. This involves imaging structures associated with internal dynamics of the mantle, particularly the core-mantle boundary region and the vicinity of the subducting lithosphere. Earthquake-related investigations include waveform modeling of body and surface waves to determine the nature of faulting and to develop seismic models for the entire rupture process. He also studies nuclear explosion sources to provide improved means for monitoring low-threshold test ban treaties. Dr. Lay has more than 240 peer-reviewed publications, he received the Macelwane Medal from the American Geophysical Union in 1991, and he is a Lifetime National Associate of the National Academy of Sciences. Dr. Lay is a fellow of the American Geophysical Union, the American Association for the Advancement of Science, and the American Academy of Arts and Sciences. He is also past chair of the Board of Directors of Incorporated Research Institutions for Seismology and previously held a faculty position at the University of Michigan from 1984 to 1989. Dr. Lay received a B.S. from the University of Rochester in 1978 and an M.S. and a Ph.D. from the California Institute of Technology in 1980 and 1983, respectively.

Michael L. Bender (NAS) is a professor of geosciences at Princeton University, where he has been since 1997. His research focuses on glacial-interglacial climate change and the global carbon cycle. This involves measuring gas properties in ice cores to date critical climate changes of the ice ages. His carbon cycle research involves characterizing the fertility of ecosystems at the global scale, at the scale of ocean basins, and at regional to local scales within the oceans. Dr. Bender is a fellow of the American Geophysical Union and is a recipient of the Patterson Medal of the Geochemical Society. He has served on numerous editorial boards and committees, including as chair of the National Oceanic and Atmospheric Administration’s CO2 Observations Advisory Group (1999-2001) and the National Science Foundation’s (NSF’s) Ice Core Working Group (1990-1997). Prior to joining Princeton, he was a professor of oceanography at the University of Rhode Island (1972-1997). Dr. Bender received a B.S. in chemistry from the Carnegie Institute of Technology in 1965 and a Ph.D. in geology from Columbia University in 1970.

Suzanne Carbotte is the Heezen Lamont Research Professor at the Lamont-Doherty Earth Observatory at Columbia University, where she has been since 1993. Her research focuses on the formation of oceanic crust at the global midocean ridge, using a variety of marine geophysical techniques. Current work involves application of seismic methods to study the alteration of the crust that occurs as a result of fluid-rock interactions on the Juan de Fuca plate and the origin of the segmentation of midocean ridges.
