Professor Nancy Knowlton is the Director of the Center for Marine Biodiversity and Conservation (CMBC) and a Professor of marine biology at the Scripps Institution of Oceanography. She also maintains a part-time position at the Smithsonian Tropical Research Institute in the Republic of Panama, where she pursues her research on coral reefs. She is well known for her studies of marine diversity, which led to the now widespread recognition that estimates of marine diversity are probably too low by a factor of ten. She received her undergraduate degree at Harvard University in 1971 summa cum laude, and her PhD at the University of California at Berkeley in 1978. She is currently a member of the Packard Interdisciplinary Science Panel, the Conservation International Marine Advisory Panel, and the Committee on Research and Exploration and the Conservation Trust of the National Geographic Society. She is a fellow of the American Association for the Advancement of Science and the Aldo Leopold Leadership Program, whose goal is to promote effective communication between scientists and the world at large. Her work has been featured by both national and international print, radio and film media, and she has provided advice on marine biodiversity issues to the World Bank, the Natural History Museum in London, and the Swedish and Taiwanese governments.
