Associate Professor Robert Clark

BSc, MStat, PhD, AStat

Dr Robert Clark is an Associate Professor in the Statistical Consulting Unit. He has extensive experience in sample surveys, statistical ecology, and applied statistics, both in research and in significant consulting projects. He has been a statistical consultant, researcher and teacher for over 25 years, including leadership roles in the Australian Bureau of Statistics, the University of Wollongong (UOW) and the ANU.

Robert is an Accredited Statistician, and an Elected Member of the International Statistical Institute. He has been an invited speaker at conferences held by the Australian, Canadian and American Statistical Associations, and he delivered the 2011 Ken Foreman lecture for the Statistical Society of Australia. He has been an associate editor for four journals including the Journal of the Royal Statistical Society Series A. He holds degrees from the University of Queensland, ANU and UOW.

Academic outputs include a major textbook on model-based survey sampling, 21 peer-reviewed journal articles and two book chapters. Robert has attracted substantial research income in major contracts and grants including an ARC linkage grant, a Statistics New Zealand (NZ) official statistics research grant, and research projects for the a variety of Australian and NZ organisations.
