Research Interests:  My research interests involve prehistoric materials conveyance, the ways in which different modes of acquisition, production and use are reflected in the archaeological record, and the relationship between these material signatures and past social, exchange, and ceremonial systems of different scales. My analytical specialization in x-ray fluorescence spectrometry has been directed toward investigating contrasts and continuities in material acquisition through time in far western North America- California and the Great Basin in particular. Other research interests include linguistic prehistory and archaeology and shell bead and ornament studies.
