Nan Crystal Arens is assistant professor in Integrative Biology at UC Berkeley and Curator of Fossil Plants in the UC Museum of Paleontology. She studies living plants, particularly tree ferns, to understand how plants interact with their environments. She studies ancient plants to understand how such ecological patterns influence evolutionary trends, particularly during moments of environmental disturbance.

Sandy Carlson received her M.S. and Ph.D. degrees in Geological Sciences from The University of Michigan. She has worked as a research scientist and professor in the Department of Geology at the University of California, Davis for more than a decade. Her research expertise concerns the biology and paleontology of brachiopods (bivalved marine invertebrates), particularly their phylogenetic relationships to one another and to other invertebrates, as well as their functional and evolutionary morphology.

Richard Cowen is a Senior Lecturer in Geology at UC Davis. He studied the paleontology of brachiopods while attending Cambridge University and he received his Ph.D. there in 1966. He began teaching at UC Davis in 1967. Dr. Cowen is interested in the functional and anatomical reconstruction of fossil invertebrates and the interrelationship between geology and people. Some of his recent projects include work on trilobite eyes and algal symbiosis in fossils.

Scott Dawson is a graduate student in Molecular and Cell Biology (MCB) at UC Berkeley whose main scientific interests are the patterns and mechanisms of evolution in microbes. Before entering graduate school at Berkeley, he was a researcher in the field of HIV molecular epidemiology at Georgetown University and at GenBank (a database of genetic sequences at the National Center for Biotechnology Information at the National Institutes of Health). After graduating this year, Scott is planning to pursue post-doctoral research in the area of the cell and molecular biology of deeply-diverging anaerobic protists.

David W. Deamer is professor of Chemistry and Biochemistry at UC, Santa Cruz. His undergraduate degree was in Chemistry at Duke University and his Ph.D. degree was in Physiological Chemistry at the Ohio State University School of Medicine. Following post-doctoral research at UC Berkeley, Dr. Deamer joined the faculty at UC Davis in 1967. In 1994 he moved to UC Santa Cruz to carry out NASA-supported research on the role of membranes in the evolutionary events leading to the origin of cellular life.

David R. Lindberg is a professor of Integrative Biology and Director of the Museum of Paleontology at UC Berkeley. He received his Ph.D. in Biology from UC Santa Cruz in 1983. Dr. Lindberg's research interests include evolution in the rocky, nearshore marine biome, with a focus on the evolution of select organisms (mostly Mollusca), the changing habitat, and the resultant interactions between organisms and between organisms and the habitat through time.

Jere H. Lipps received his Ph.D. in Geology at UCLA, having decided to be a paleontologist when he was 7. He has taught courses at UC Davis, UC Bodega Marine Laboratory, UC Berkeley, and the UC Gump Biological Station, Moorea. He is professor of Integrative Biology at Berkeley, past director of the Museum of Paleontology at Berkeley, and past president of the Paleontological Society and Cushman Foundation. His research interests focus on the evolutionary history of the marine biosphere.

Kevin Padian is professor of Integrative Biology and a Curator in the Museum of Paleontology, UC Berkeley. His research focuses on various aspects of macroevolution and paleobiology, particularly of vertebrates. He is interested in the origins of major adaptations, or how "great ideas" in evolution get started. He has worked extensively with many levels of public education, particularly through the state Dept. of Education, and also the National Center for Science Education, of which he is currently President.

Bruce H. Tiffney received his B.S. in Geology from Boston University and his Ph.D. in Botany from Harvard University. During the period 1977 to 1986, he was assistant, then associate professor, at Yale University and curator of the herbarium and paleobotanical collections at the Peabody Museum of Natural History. He moved to UC Santa Barbara in 1986, where he is now professor of Paleobiology in the Department of Geological Sciences, with adjunct status in Biology. His research interests are broad, ranging from the basic features of the evolution of plant adaptations to land, through plant-vertebrate interactions, to the systematics and evolution of the flora of the Northern Hemisphere in the last 65 million years.

Tim White is a professor of Integrative Biology and co-Director of the Laboratory for Human Evolutionary Studies at UC Berkeley. He is one of the leaders of the Middle Awash project in Ethiopia, and has worked on human origins in laboratory, museum, and field settings across the Old World. His most recent publications include the description of 2.5 million-year-old fossils and butchery traces from Ethiopia.
