Heather J.H. Edgar, PhD, D-ABFA, leads the Bridge Lab, located in Anthropology Patio 210. Research topics focus on the structure of human phenotypic variation, interactions between human culture, history, and biology, and health and wealth disparities now and in the past. Research projects in the lab draw on methods and materials from bioarchaeology, forensic anthropology, and human biology. From an evolutionary perspective, human biological methods inform us about living people with detailed, cross-sectional data, while bioarchaological methods provide less-detailed but longitudinal data. Current research utilizes CT scans, 2D x-ray images, photomontages of tooth surfaces, photogrammetry, and dental morphology. The lab is also associated with the Office of the Medical Investigator (OMI).
