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. Most of the graduate students that I supervise work on projects related to palaeoecology of the Arctic, Andean agropastoral systems, or methodological aspects of stable isotope analysis as applied in archaeological contexts.
