He received a B.S. in physics from Rhodes College and a geoscience Ph.D. with emphasis in seismology form the University of Colorado, Boulder. He was the director of CERI from its founding in 1978 to 1992. His research has focused on the seismicity and seismotectonics of plant interiors, principally stable continental regions. The rare, large, midplate earthquakes such as New Madrid 1811 and Charleston 1886 constitute an important and poorly understood element in both seismic hazard assessment and the active tectonics of so-called "stable" continental crust. Relating current earthquake activity to strain rate and the geological and geophysical evolution of continental crust are present research topics.

Marlene Zuk received her B.A. at the University of California, Santa Barbara, and obtained her Ph.D. from the University of Michigan. After doing postdoctoral work at the University of New Mexico, she took a position as associate professor of biology at the University of California at Riverside. Her research interests center on animal behavior, particularly mate choice and the evolution of sex differences; and the effects of parasites on host ecology and behavior.More recently, her longstanding commitment to feminism has dovetailed with her academic interests, particularly the relationship between feminism and science.
