My research interests include the prehistory of the eastern United States and Andean South America, the origins and health consequences of social and economic transitions (agriculture, state, European contact), and skeletal biology as a means of interpreting the nutritional and health status of past populations. I approach health as a process that is influenced by biology, behavior, ecology, and environment. The dynamic interplay of those variables acts to create dynamic disease environments that have shifted through time and space, and are continuing to shift. Although I focus on past populations in my research, I am very interested in contemporary global health issues. Some of my research projects regarding nutrition and health are discussed below. I began working with populations that inhabited the southeastern United States in 1983, principally with protohistoric populations that lived during the first 100 years of contact with Europeans who came to explore and colonize the Atlantic coast. I worked on St. Catherines Island at the Spanish mission site of Santa Catalina de Guale, Georgia, with the American Museum of Natural History, the subject of my M.A. thesis (1987, Northern Illinois University), and at Tatham Mound, an early contact mortuary locality in central peninsular Florida with the Florida Museum of Natural History, the subject of my Ph.D. dissertation (1991, University of Illinois Champaign-Urbana). I turned my attention toward several issues of coastal adaptation in 1995, when I began to reconsider some of the coastal populations of Georgia and Florida that I had previously examined. As a relatively new professor at East Carolina University, I constructed a series of questions I wanted to ask about coastal foragers and their transition to agriculture, the nutritional and health consequences of the agricultural transition, and the nutritional and health conditions of coastal foragers who had not yet made the transition to agriculture. With funding from the National Science Foundation, I conducted that study between 1997 and 1999, and it was recently published (Foraging, Farming, and Coastal Biocultural Adaptation in Late Prehistoric North Carolina, University Press of Florida, 2002). I am also very interested in the origins of the state in the Lake Titicaca region in South American Andean populations. I have been working for several years with formative period remains from the Bolivian side of Lake Titicaca on a multidisciplinary study headed by Karen Chavez (recently deceased) and Sergio Chavez of Central Michigan University. Finally, in my role as a forensic anthropologist I have served as a consultant on several occasions to law enforcement officials. Those experiences have been supplemented by replication experiments designed to facilitate our knowledge of how bone responds to certain types of growth and/or damage. With my graduate and undergraduate students, I have investigated sharp metal weapon and blunt weapon trauma, as well as methods of age and sex estimation.
