Sebastian Scheiffele is an archaeologist and Ph.D. student in the Center. His major research interest focuses on the interdependence and coevolution of techno-cultural traits and related cognitive abilities. He uses behavioral patterns observable in the archaeological record as proxies for his inferences. For his doctoral study, Mr. Scheiffele examines late Middle Stone Age archaeological assemblages from eastern Africa. He is interested in understanding technological/behavioral dynamics that may have been decisive in the successful adaptation and dispersal of Late Pleistocene Homo sapiens.
