Rhonda Quinn approaches anthropological questions with (bio)geochemical methodologies. Beginning at the undergraduate level and now as an associate professor, she integrates stable isotopic and elemental data with environmental and cultural information of modern and fossil humans to understand human behavioral and morphological adaptation to ecosystems spanning millions of years to more recent times. At Seton Hall University, a primarily undergraduate institution, she directs an anthropological biogeochemical laboratory that functions as a teaching and research facility utilizing materials from forensic, archaeological, and paleoanthropological contexts.
