Stable isotope analysis particularly relating to paleodiet and mobility patterns, indigenous plant use and cultivation, food practices, human-environmental interactions, traditional ecological knowledge, agricultural origins, soil and land formation processes, geoarchaeology.
Current Projects: My current research explores the spatial and temporal differences in diet among prehistoric populations in British Columbia, specifically reconstructing diet and diet changes through time along the Fraser River from Vancouver into the Interior of British Columbia. Through using stable isotope analysis as a methodological tool I hope to re-evaluate resource acquisition and utilization, test the emerging evidence of diet diversity and variability that comes from other methods (botanical, paleobotanical, and faunal remains) and finally compare these lines of evidence with the narratives recounted in oral histories and traditional use studies.
