Curtis Runnels is Professor of Archaeology at Boston University.
He has conducted research in Greece, Turkey, and Albania since 1973, primarily on the Palaeolithic and Mesolithic. Recently his research has been focused on early hominin dispersals and Pleistocene seafaring as a result of the discovery of Palaeolithic stone tools (age greater than 130,000 years) on the Greek island of Crete in 2008-2009. This interest led him to consider the peopling of the New World as viewed from an Old World perspective, and to undertake a re-evaluation of some early claims for pre-Clovis sites in North America. In recent years he has examined collections of stone tools in museum collections, among others the Peabody Museum (Harvard), the New Jersey State Museum in Trenton, the Museum of Man in San Diego, and the Museum of Anthropology at the University of Denver.
Dave May is a Professor of Geography at the University of Northern Iowa.
He has conducted geoarchaeological research in the Great Plains of North America since 1982, primarily on Paleoindian and pre-Clovis sites focusing on their alluvial stratigraphic context, and more broadly, Late Pleistocene landscape evolution. He has worked on the alluvial and eolian stratigraphy of many mammoth sites in northern Kansas and Nebraska with Steve Holen. Dave is planning to work around Pleistocene playas in western Kansas in the near future.
Kathleen Maule Holen received an MA in Archaeology with Distinction in 2009 from the University of Exeter, UK.
She previously received an MS from the University of Michigan in 1985 and retired as a Nurse Practitioner in 2010 to begin a career in archaeology. Kathleen founded the Center for American Paleolithic Research in 2012 and continues as the Administrative Director. She has participated in the research of Steven Holen since their marriage in 2001. Together they continue to investigate early human dispersals into the Americas. In addition, she studies prey animal bone modification and its implications for human behavior, expedient bone tool manufacture and use, cognitive archaeology and the archaeological importance of dog domestication. Kathleen has regularly presented papers and posters at annual archaeological conferences and is coauthor on two book chapters that document evidence of the early peopling of the Americas. She has presented and published on archaeological topics for children. Along with Steven, she has lectured to numerous avocational archaeological societies as a participant in the lecture series sponsored by the Archaeological Institute of America.
George Jefferson presently works for the Colorado Desert District of the California Department of Parks and Recreation as District Paleontologist (emeritus).
George Jefferson presently works for the Colorado Desert District of the California Department of Parks and Recreation as District Paleontologist (emeritus). The District encompasses all State Parks within southeastern California, including Anza-Borrego Desert and its rich late Tertiary and Quaternary, marine and terrestrial vertebrate paleontological record.
George earned his undergraduate and masters degrees in geology and paleontology at the University of California, Riverside, finishing in 1968. His research interests have centered on Plio-Pleistocene vertebrate faunas of the American southwest. George also has extensive archaeological experience. For much of his professional career George was head curator of the Rancho La Brea collections at the Page Museum in Los Angeles. Recent major publications include Stratigraphy and paleontology of the middle to late Pleistocene Manix Formation, and paleoenvironments of the central Mojave River, southern California, and Fossil Treasures of the Anza-Borrego Desert, which is nominated for a national Benjamin Franklin Award for science and education books.
Dr. Ruth Gruhn is Professor Emerita in Anthropology at the University of Alberta in Edmonton, Alberta, Canada.

She and her late husband Alan Bryan have long supported evidence for a settlement of the Americas in the late Pleistocene. Fifty years of fieldwork include excavations at early archaeological sites in Alberta, Idaho, Nevada, Baja California, Guatemala, Nicaragua, Venezuela, and Brazil.
