Craig studied economics at Cambridge and MIT. He worked in strategy consulting at both McKinsey & Company and Accenture.
He then decided to follow his childhood passion for archaeology and returned to Cambridge for a MPhil (thesis on the Neolithisation of Italy) and a PhD (thesis on spatial and demographic analyses of Iron Age Valcamonica and its rock-art sites, villages and cult sites). Craig then took part in a 3 year EU funded project (http://www.3d-pitoti.eu/) to develop a new 3D scanner for rock-art, which was tested and refined at sites in Valcamonica. He has active research programmes in Valcamonica (statistical analyses of various aspects of rock-art) and Puglia (trace element analysis of Neolithic pottery to reconstruct the exchange and sourcing networks of Western Europe's first agricultural society).
