Areas of interest

I am interested in integrating archaeological data with ethnohistoric sources and oral history to learn about aspects of Indigenous history, culture, and landscape use in the Salish Sea and Northwest Coast. My interest in these subjects derives from their significance to the Indigenous people that I work with and relevance to many important contemporary issues.

I am an anthropological archaeologist with 15 years of experience working directly for Sts’ailes, a Coast Salish Halkomelem speaking community on the Harrison River. During this time, I have led and supported multi-disciplinary initiatives designed to promote and enhance ecological health and resiliency, social well-being, and cultural revitalization in Sts’ailes and elsewhere in the Salish Sea. I continue to work closely with Sts’ailes Chief & Council on matters relating to land use planning, environmental stewardship, governance, and negotiations. In 2020 I was honored by the Sts’ailes with the traditional name: Xá:tl’hiqelemtel, which translates to: “Strong Winds, Rough Water” in recognition of my service to, and adoption by, the community. I have coordinated and instructed numerous research-based archaeological field schools and excavation programs. I am also a Northwest Coast Permit Holder and Field Director and have been involved with CRM archaeology throughout my career.


My research focus has been on the archaeology, ethnohistory, and oral history of settlements, landscapes, waterways, demography, technology, and social change in the Sts’ailes-Coast Salish region. Publications have featured in international journals including Journal of Anthropological Archaeology and Ethnohistory. In 2021 I was recognized by the American Society for Ethnohistory for the Best Article in the field of Ethnohistory for a paper relating to Indigenous oral history and sustainable salmon fishing.

Current research continues to focus on interpretations of society, socio-political processes, governance, traditional law, historical events, environmental entanglements, and technological change through diachronic, multi-scalar, and multi-disciplinary studies.

Other Activities

When I’m not doing archaeological fieldwork, reading, and writing, I love to spend time with friends and family hiking and canoeing, playing soccer, and travelling.
