Andrew joined Far Western in 2012 as a Principal Investigator. He is interested in human evolution and ecology, particularly as it applies to hunter-gatherers and agriculturalists of the western United States and southern South America. Drew has been especially involved in the use of faunal remains and stable isotope analyses to understand changes in resource exploitation and human-environmental interactions across the Late Pleistocene and Holocene. He and his colleagues have published their research in regional and international journals, including American Antiquity, the Journal of Archaeological Science, the Journal of Anthropological Archaeology, Current Anthropology, the International Journal of Osteoarchaeology, World Archaeology, Quaternary Science Reviews, Quaternary International, Utah Archaeology, Intersecciones, Magellania, and Nature. Along with others at Far Western, Drew is currently working to clarify the nature of Paleoarchaic occupations in the northwestern Mojave Desert and pan-Holocene changes in faunal exploitation across the northern Great Basin. He also remains actively involved with Latin American colleagues studying the role of domesticates and wild resources along the southern agricultural frontier.
