Regents Professor Emeritus
Archaeology and Evolutionary Anthropology
Kohler applies method and theory from the study of complex adaptive systems to the study of prehistoric societies. He received his A.B. in General Studies from New College of Sarasota, and his M.A. and Ph.D. degrees in Anthropology from the University of Florida. His dissertation research on Weeden Island societies involved sampling the McKeithen village in North Florida. Since arriving at WSU, he has increasingly specialized in Southwestern archaeology. In the late 1970s through the mid-1980s, he collaborated with William D. Lipe on the Dolores Archaeological Program in southwestern Colorado. Since then, he has directed excavations in Bandelier National Monument in New Mexico, and coordinated the interdisciplinary NSF Coupled Natural & Human Systems-funded “Village Ecodynamics Project”to understand the causes for changes in settlement systems in the eastern Southwest between A.D. 600 and 1760. He is a Research Associate at the Crow Canyon Archaeological Center, Cortez, and an External Professor at the Santa Fe Institute, New Mexico.
Much of his work involves quantitative analysis of archaeological data or simulation of aspects of prehistoric behavior. He is especially interested in cooperative behavior, wealth inequalities and their consequences, reciprocity, and other processes with evolutionary implications in Neolithic societies, and large-scale patterning in prehistoric societies. In April 2004 he completed a four-year term as editor of American Antiquity. For a decade he also served on the Board of Directors of Digital Antiquity, an initiative to aggregate and preserve archaeological digital data and make it broadly accessible. His current research (with ASU, Crow Canyon Archaeological Center, and UIUC) includes the SKOPE project to make interpreted paleoenvironmental data widely accessible, and an NSF IBSS-funded project (with researchers at the Santa Fe Institute) to analyze information flows in human organizations. With Amy Bogaard, University of Oxford, he directs the Global Dynamics of Inequality Project (GINI), which is run through the Center for Collaborative Synthesis in Archaeology at the University of Colorado-Boulder.
In 2010 he was recognized by the SAA with its Award for Excellence in Archaeological Analysis, and in 2014 the AAA honored him with its Alfred Vincent Kidder Award for Eminence in the Field of American Archaeology. He is a Fellow of the AAAS and a member of the Washington State Academy of Sciences and of the National Academy of Sciences. He was in residence as an Invited Scholar at the Research Institute for Humanity and Nature in Kyoto for most of Fall Semester 2019, and served as the Johanna-Mestorf-Chair at Christian-Albrechts-Universität zu Kiel, Germany, in Fall 2021 in association with the ROOTS project. In Spring 2023 he is serving as a Visiting Fellow in the Department of Archaeology, University of Durham (UK).
