I am currently conducting major archaeological research projects in Indonesia and East Timor investigating the earliest evidence for human settlement on potential pathways through Wallacea. This project complements and builds on previous research in eastern Maluku, and Papua New Guinea and the Kimberley region of northern Australia which focused on Pleistocene settlement and subsistence and interaction and exchange. I am also interested in the rock art of northern Australia and Island Southeast Asia and evidence for symbolic exchange in the mid to late Holocene.
