My research specialization is reconstructing the methods and techniques used to flake stone into tools, using toolmaking skills I have learned over the last 30 years. My research involves modelling the ‘design space’ of stone flaking and the implications of this for toolmaking behaviour in Australasia and beyond. An aspect of my work is experimentally-based and explores the range of variation in stone tool shapes generated by simple stone flaking techniques, including those made by Homo floresiensis ('hobbits') on Flores, Indonesia. A second area of research involves reconstructing and interpreting complex stone tool-making processes from various parts of the world, including Australia, Indonesian, North America, and Europe.
