In the past few years, I have returned to those roots, especially Ancestral Pueblo archaeology. Links to recent articles can be found in the publications tab of this site. In the next years, I will explore the cause of the modern diabetes epidemic among southwestern USA tribes from this archaeological perspective. With regard to diabetes, I have collected dietary data for the U.S. Southwest that spans a 10,000-year period. These data, when interpreted in context of new nutritional data that have been collected by other researchers, provide important insight into the relationship of plant use to cultural development and its effect on the evolution of human metabolism. The main aim of my career between 1985 and 2005 was to find explanations for modern patterns of disease in the archaeological and historic record. I developed a new area of specialization, called archaeoparasitology. This is an approach to understanding the evolution of parasitic disease. It is also the topic of a course I developed for UNL students.
