I did my PhD research on the prehistoric Mississippian cultures of the eastern United States, and found that interactions between groups were common and had been shaping Native American cultures for centuries. Native Americans approached contact with the Jesuits simply as another in a long string of intercultural exchanges. I also found that relatively little research had been done on Native American interactions and decided that comparative research was a good place to begin examining the topic. I have been pursuing comparative archaeological research ever since.
During my graduate education I was lucky enough to learn the specialized methods of archaeological survey, particularly those done using remote sensing instruments. This specialization has allowed me to travel all over the world to conduct surveys and to learn about the amazing diversity of the archaeological record.
I am currently a professor of anthropology and museum studies at Lawrence University in Appleton, Wisconsin where I teach a variety of courses in archaeology and museum studies to undergraduate students. I am also an external professor at the Santa Fe Institute in Santa Fe, New Mexico, where I work on comparative approaches to understanding cultural evolution. Finally, I am a research associate for the Human Relations Area Files, which is the primary institution supporting comparative research in the social sciences.
And I continue to do archaeological research. Currently my students and I are busy conducting surveys of pioneer cemeteries using remote sensing instruments to locate unmarked graves in order to preserve them.
