I was the founding Director of the Australian Research Centre for Human Evolution at Griffith University in Brisbane, from January 2016 to February 2020. I spent most of my career at the Research School of Earth Sciences at the Australian National University in Canberra. My research focussed on the virtual non destructive dating using ESR and U-series. This has given me access to a large number of important human fossils, including Apidima, Atapuerca, Border Cave, Banyoles, Florisbad, Irhoud,  Homo naledi, Homo luzonensis, Homo floresiensis, Irhoud, Kabwe, Mungo 3,, Sidron, Skhul, Swartkrans, Tabun, Thomas Quarry, Wajak, WLH50 etc. The results led to major revisions of our understanding of human evolution showing that modern humans occurred around 300,000 years ago in Africa (Irhoud) and that the earliest European modern humans may be as old as 200,000 years (Apidima). In the last 5 years I co-authored more than ten papers in Nature and Science.
