About

I am an anthropological archaeologist who works on the earliest expansionist states of South America. My scholarly interests are focused on the development of ideological systems associated with early “global” polities. I am very interested in understanding the material basis for the interaction between different component groups in first generation heterogeneous expansive states, and the nature of the relationships between peer polities at this political scale.

My research has focused on one of the few cases where we can archaeologically document extensive long term direct contact between two such polities: Wari and Tiwanaku.  I am currently undertaking research at the only known site of such direct interaction. I also work with colleagues in other regions under the influence of the same cultures in order to obtain a comparative perspective on this relationship.
