Consulting Experience

Alan is a leading senior heritage consultant. Through his recently completed PhD (March 2015) Alan has developed research publications on Aboriginal demography, which are internationally cited. He has been involved in cultural resource management (CRM) in the Sydney Basin (and elsewhere) for over 12 years, and this includes management of some of the largest salvage excavations undertaken in that time. He is one of the few archaeological consultants to have undertaken CRM works of a high research quality and subsequently published them in peer reviewed academic journals (e.g. Williams et al., 2012, 2014).
