Raleigh Martin is an Earth-surface process geoscientist interested in enabling open knowledge, data, and policy in the geosciences. Prior to serving as the 2019-20 William L. Fisher Congressional Geoscience Fellow, Raleigh is completing an American Association for the Advancement of Science (AAAS) Science & Technology Policy Fellowship in the Directorate for Geosciences at the U.S. National Science Foundation (NSF). At NSF, Raleigh is helping to allocate infrastructure investments and to refine public access policies to advance geoscience research discovery through improved data access and reuse. Prior to NSF, Raleigh was a postdoctoral researcher at the University of California, Los Angeles (UCLA), where he studied wind-driven sediment transport processes shaping coastal and desert sand dunes and generating atmospheric dust. Raleigh earned his B.S.E. in Geological Engineering from Princeton University and his Ph.D. in Geology at the University of Pennsylvania, where his doctoral research focused on understanding the statistical variability of sediment transport and geomorphology in rivers.
