Emergence of social and political complexity, origins and spread of agriculture–especially maize; Mesoamerica (Early Formative and Postclassic Chiapas, Mexico), North America (Coast Salish peoples of British Columbia).
I joined the faculty at UBC in 1986, a year after completing my Ph.D. in Anthropology, with a specialization in Archaeology, at the University of Michigan. My doctoral research in the early 1980s examined the household archaeology of the Postclassic period Maya centre of Canajasté on the Lagartero River near the Chiapas-Guatemala border in the Upper Grijalva Tributaries region of SE Mexico. Since then I have carried out archaeological research in Chiapas, Mexico and the Salish Sea region of British Columbia, Canada.
Soon after completing my doctoral research, I teamed up with John Clark, former Director of Brigham Young University’s New World Archaeological Foundation, to begin a research project investigating the emergence of complex social and political systems in the Soconusco region on the Pacific coast of Chiapas, dating between about 4000 and 3000 years ago. These Early Formative period societies (that we have dubbed the Mokaya) comprised some of Mexico’s earliest villages, and developed practices that later became common throughout Prehispanic Mesoamerica (for example, they built Mesoamerica’s earliest known ballcourt–the subject of Warren Hill’s UBC PhD in 1999). Richard Lesure (UCLA) later joined the project, and, along with several other archaeologists, our ongoing research documents the transformations that took place as people became increasingly dependent on agriculture (including maize cultivation), lived in permanent settled communities, and developed complex social and political hierarchies. Our work in Chiapas has been funded by the generous support of SSHRC Canada, and the BYU-New World Archaeological Foundation, along with many other agencies.
Between 1992 and 2007, I conducted archaeological research in the Fraser River Valley of Southwestern British Columbia in partnership with members of Stó:lō Nation’s Research and Research Management Centre, including Dr. Dave Schaepe, as well as research partners from a number of universities. One long-term project concentrated on the ancient village site of Scowlitz (Qithyil), located 100 km east of Vancouver within the traditional territories of the Sto:lo Coast Salish peoples. Working with Dr. Dana Lepofsky (Simon Fraser University), our project team–which has included many UBC, SFU, and UCLA archaeology field schools–has investigated how both households and cemeteries formed an integral part of Coast Salish social, political and economic and spiritual life. This project has as it main goal the exploration of Coast Salish identities as expressed in house structures and village settlement layouts extending from about 3000 years ago to the beginning of European colonization of the region in the early-1800s [link to FVAP SAA research posters].
My most recent work, since 2007, has focused on the origins and spread of maize agriculture in the Americas. Working with Dr. Bruce Benz (Texas Wesleyan University) our research team is studying archaeological maize collections stored in museums and other institutions in about eight different countries throughout the Americas. Our research goals are to directly date the samples using AMS radiocarbon dating, conduct detailed morphological analyses of maize cobs, and extract and characterize ancient maize DNA (see our new publication in Science by Kelly Swarts, et al. 2017).

During the past eight years or so I’ve been working with a team of archaeologists and other specialists to trace the history of cacao use in Latin America. Working with Drs. Sonia Zarillo, Terry Powis, Francisco Valdez, Nilesh Gaikwad, and Claire Lanaud (and many other members of our large international team), we’ve been looking for evidence of Theobroma cacao in pottery and other ancient tools at early settlements in Ecuador (Nature Ecology & Evolution 2018–Behind the Paper by Sonia Zarrillo). This project is entering a new phase of research in partnership with UBC’s Pacific Centre for Isotopic and Geochemical Research (PCIGR) directed by Professor Dominique Weis and her team of researchers.
