Sam is a Far Western Geoarchaeologist at the Davis Branch. He received his M.A. in 2005 and Ph.D. in 2016, both in Applied Anthropology, from Oregon State University. Sam has 20 years of conducting inventory, monitoring, testing, and data recovery projects in numerous regions; including the Pacific Coasts of Oregon and Washington, the Columbia Plateau, the northern Great Basin, the Rocky Mountains, Baja California, Mexico and Central California.
Sam’s research interests include soil geomorphology, site taphonomy, quantitative lithic analysis, lithic technologies, trace element analysis using XRF and INAA methods, and the peopling of the Pacific Coast. He is currently involved in research projects focused on the arid soilscapes and prehistory of the Central Desert region and Cedros Island in Baja California, Mexico.
