David Rand joined the Brown faculty in 1991, after receiving a B.A. at Harvard and a PhD at Yale in Biology, and postdoctoral training in population genetics at Harvard. He is the Stephen T. Olney Professor of Natural History in the Department of Ecology and Evolutionary Biology, where he is Chair of the Department. He teaches undergraduate courses in evolutionary biology, evolutionary genetics, and graduate seminars on ecological, evolutionary and population genetics. His research focuses on the coevolution of nuclear and mitochondrial genomes, the role of mitochondrial mutations in fitness, aging and disease, and the environmental genomics of adaptation in marine organisms, with funding from the NIH and NSF. He is Director of an NSF IGERT Training Grant in Reverse Ecology bridging graduate programs in Ecology and Evolutionary Biology, the Center for Computational Molecular Biology, Applied Math and the Marine Biological Laboratories in Woods Hole. He is Principle Investigator of an NIH COBRE award focusing on the Computational Biology of Human Disease. He is past president of the American Genetic Association and an elected Fellow of the American Association for the Advancement of Science.
