Kelly J. Knudson, Ph.D.

The Archaeological Chemistry Laboratory, directed by Kelly J. Knudson, operates under the aegis of the Center for Bioarchaeological Research and the School of Human Evolution and Social Change at Arizona State University.

Research areas include biogeochemistry and analysis of stable isotopes of elements such as strontium, lead, carbon and oxygen. This research helps archaeologists better understand human migration and diet in the past. Current isotopic work focuses on Andean residential mobility. In addition, chemical analysis of archaeological and ethnoarchaeological soils help identify activity areas in the past. In our work in Alaska, we use trace element concentration analysis to examine changing subsistence practices over time.

Current and future students and collaborators can learn more about our laboratory facilities and are encouraged to take ASM 494/591: Human Behavior through Bone Chemistry.
