Faculty-Student Research

My current research involves the study of archaeological artifacts using chemical techniques.  In collaboration with the Office of the State Archaeologist of Iowa at the University of Iowa, we are using X-ray fluorescence and other methods to determine the concentrations of trace metals in pottery fragments from archaeological sites in Iowa and South Dakota.  Our goal is to shed light on the origin and possible exchange of pottery between cultures that existed ~800-1000 years ago.
