I am Distinguished Professor of Paleobiology at Scripps Institution of Oceanography, University of California, San Diego where I work on micropaleontology of the open oceans, warm climate dynamics, and human impacts on marine ecosystems. Much of my research is built around Scientific Ocean Drilling where I have led two expeditions, sailed on four others, been an author of numerous drilling proposals, and have served on the scientific panels and program offices that direct this international effort. I have also led oceanographic cruises to the North Atlantic, Mediterranean and NE Pacific in addition to land-based field studies in Greece, Israel, Sicily, the Alps, South Africa, New Zealand, Australia and western North America. I am the Curator of the SIO Geological Collections and have worked to set up the Center for Marine Biodiversity and Conservation (CMBC) and the Scripps Center for Marine Archaeology (SCMA), to link human affairs to Earth’s environmental history. My training includes a BS from UC Santa Cruz, my MS from the University of Arizona, my PhD from Harvard University and experience as a postdoc and research scientist at Woods Hole Oceanographic Institution. I am author of 143 research papers and 7 books.
