My research uses chemical techniques (stable isotope analysis) to better understand how humans interacted with their environment in the past. My research can be divided into several different thematic areas, which can be found under the "Research" tab at the top of this page.
I am primarily interested in the long-term ecodynamics of marine environments in the North America Arctic (Canada, Alaska, and Greenland) and the Northeast Pacific (British Columbia and California).
I am interested in better understanding how humans managed or herded domestic animals in the past, with a particular emphasis on the Andean region and Pacific coast of South America (Peru and Chile).
To gain greater insight into how what happened in the past, I conduct experimental studies to provide a basis with which to interpret the archaeological record. This includes controlled laboratory or growth studies, as well as various modern natural and anthropogenic ecosystems.
