He studies Paleoindian archaeology, lithic technology, and cultural evolution.David Kilby is an Associate Professor at Texas State University and Director of the Ancient Southwest Texas project. Current field research is focused on Bonfire Shelter and the Paleoindian occupation of the Lower Pecos region. His interests include North American Paleoindians, hunter-gatherers, geoarchaeology, lithic technological organization, paleoenvironments, landscape archaeology, and behavioral ecology.Marcus J. Hamilton is an Associate Professor of Anthropology at the University of Texas at San Antonio, and previously held positions at the University of Missouri, the Santa Fe Institute, and the University of New Mexico. He researches hunter-gatherer societies in the past and present, particularly focusing on the evolutionary ecology of human-environment interactions. His archaeological area of interest is Paleoindian North America.Jason M. LaBelle is an Associate Professor of Anthropology at Colorado State University, where he directs the Center for Mountain and Plains Archaeology. Over the past 25 years, he has supervised field and lab projects related to hunter-gatherer reoccupation, variation in Paleoindian sites, thermal features, high altitude game drives, Fremont granaries, and lithic caches.Kelton A. Meyer is a PhD student in the Department of Anthropology and Geography at Colorado State University. He is a field and lab director for the Center for Mountain and Plains Archaeology. His current research focuses on high altitude settlement systems in the Rocky Mountains, Paleoindian lithic technology, and spatial statistical modeling.Jacob Holland-Lulewicz is currently Lecturer in Archaeology at Washington University in St. Louis. His research applies quantitative methods to the exploration of the long-term Indigenous histories of North America with a particular focus on the evolution of social networks and institutions of governance.Brian Andrews is an Associate Professor of social science at Rogers State University in Claremore, Oklahoma. He has conducted archaeological research throughout the Great Plains and Rocky Mountains, examining questions of mobility, settlement, technology, spatial patterning, and social organization.Brooke M. Morgan is Curator of Anthropology at the Illinois State Museum. Her research interests include lithic technology, hunter-gatherer community organization, and engaging with descendant communities.Brendon Asher is the Director of the Blackwater Draw National Historic Landmark archaeological site and an Assistant Professor of anthropology at Eastern New Mexico University. His research includes Paleoindian lithic technology, lithic procurement, and landscape use.Vance T. Holliday received his PhD in Geosciences from the University of Colorado in 1982. He was on the Geography faculty at the University of Wisconsin-Madison (1986-2002) and is now in both Anthropology and Geosciences at the University of Arizona. He is Executive Director of the Argonaut Archaeological Research Fund, devoted to exploring the early peopling of the greater Southwest. His interests include Paleoindian archaeology and geoarchaeology as well as Quaternary soils and paleoenvironments, and Paleolithic geoarchaeology of eastern Europe.Greg Hodgins is the Director of the University of Arizona Accelerator Mass Spectrometry Laboratory. His research focuses on archaeological and geological dating.Todd Surovell is a Professor of Anthropology at the University of Wyoming. He has expertise in Paleoindian archaeology, geoarchaeology, ethnoarchaeology, and lithic technology.
