Research and Practice Interests


My primary research interests are in paleoethnobotany and paleoecology. I have conducted field research in many areas of North America, studying indigenous groups in Guatemala, Belize, Honduras, Mexico and El Salvador, as well as in the southwestern and southeastern US. To develop a greater understanding of how early cultures manipulated their environment through their agricultural and other land-use practices, I have examined the way in which indigenous people, including the Jicaque, Paya and the Kekchi-Maya, use plants. Much of my work has focused on the archaeobotany of the ancient Maya and Olmec, studying the differences in dietary habits among groups of varying economic status. Currently, I am investigating the land use practices of the ancient Maya at Tikal in Guatemala. I welcome students interested in pursuing compatible research projects.
Sunflower (Helianthus annuus) as a Mesoamerican domesticate sponsored by the National Science Foundation.
Agroforestry and water management of the ancient Maya at Tikal (sponsored by the National Science Foundation, the Wenner Gren foundation and the Alphawood Foundation).

Plans for the rehabilitation of the White Water Shaker “Trustee’s Office” building. Our goal is to reuse this historic structure for classroom and residential space for those conducting research and taking classes at the UC field station. Click here to read full report.
