My research focuses on human biocultural evolution tracked by the relationships between technology, cognition, and environmental change in the archaeological record. I ask the question, to what extent differences in human behaviour can be explained as adaptive responses to specific habitats. My career focus has been on investigations of the later Pleistocene evolution of hunter-gatherer behaviour in sub-Saharan Africa, through experimental archaeology, lithic analysis and the recovery of new field data. My current research and teaching targets two key themes within archaeology: 1) Understanding the role of technology in human behavioural and cognitive evolution; and 2) Unravelling the relative contributions of different habitats to human evolution.
