Arch C. Johnston is professor of geophysics at the University of Memphis and director of research at its Center for Earthquake Research and Information (CERI). 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.

His research interests concern the breakdown of collagen and the extracellular matrix in diverse biological systems and processes including uterine involution, cervical dilatation, ovulation, wound healing, breast cancer, and osteoarthritic cartilage. Many of these problems are united by the common theme of matrix metalloproteinase activity and inhibition. He serves on the editorial boards of Arthritis and Rheumatism and Connective Tissue Research and has edited several books including: Joint Cartilage Degradation and The Extracellular Matrix of the Uterus, Cervix and Fetal Membranes.

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.
