Ancient Andean States through Biogeochemistry and Bioarchaeology

Speaker: Kelly J. Knudson

With its long history of research and excellent preservation, the ancient Andes are ideal for the study of political integration and the formation and collapse of states and empires. Here, I will discuss the rise and fall of the Middle Horizon (AD 500-1100) Tiwanaku polity of southern Peru, western Bolivia and northern Chile by integrating data from bioarchaeology and biogeochemistry with other lines of archaeological data.

Kelly J. Knudson is an assistant professor in ASU's School of Human Evolution and Social Change. She specializes in analyzing chemical signatures in human tooth enamel and bone to explore patterns of subsistence behavior and migration.
