RESEARCH INTERESTS: My research focuses on past interrelationships between people and plants or what is called “paleoethnobotany.”  I am particularly interested in the development of agriculture in the Midwest.  What kinds of plants did people grow?   What techniques did they use to grow the crops?  How did they process them?  How did the growth of these plants influence social identity, economic and political organization, or other aspects of human culture? To these ends, I have analyzed archaeological plant assemblages from the Lower Missouri and Middle Mississippi River valleys and recently shifted my attention to the analysis of a series of plant assemblages from northeastern Arkansas

In addition, I am fascinated by how ancient plant remains are preserved and recovered from archaeological contexts and how cultural and natural processes influence our abilities to interpret archaeologically derived plant remains. As a result, I have conducted experiments, documented observations in the field, and contributed to discussions of paleoethnobotanical methods.

I am also interested in applied or public archaeology and museums. I recently returned from two years working at the Springs Preserve in Southern Nevada and spent six years serving as the Curator of Native American Ethnology at the Missouri History Museum. At both institutions, I curated exhibits and organized and presented public programming to make archaeology more accessible to the public. With the same objective in mind, I continue to work with individuals and organizations in the greater St. Louis area.
