Robert Clark is an Associate Professor in Statistics, an Accredited Statistician, and an Elected Member of the International Statistical Institute. Robert’s research interests broadly span the analysis of informatively selected samples, design of sample surveys and observational studies, small area estimation, analysis of binary data, and sampling subpopulations. He has extensive experience in sample surveys, statistical ecology, and applied statistics, both in research and in significant consulting projects. Robert’s work has attracted substantial research funding, including through an Australian Research Council Linkage Project, a Statistics New Zealand official statistics research grant, and research projects for a variety of Australian and New Zealand organisations. His research has been published in leading scholarly journals including the Journal of the Royal Statistical Society Series A and C, Statistics in Medicine, New Phytologist and the International Statistical Review. Robert also authored a major textbook on model-based survey sampling and a number of book chapters. He has been an invited speaker at conferences held by the Australian, Canadian and American Statistical Associations, and has delivered the Ken Foreman lecture for the Statistical Society of Australia. Robert has also been an Associate Editor for a number of journals including the Journal of the Royal Statistical Society, Series A.
