Dr. Andriëtte Bekker is a professor and the current head of the Department of Statistics at the Faculty of Natural and Agricultural Sciences, at the University of Pretoria. Her expertise lies in statistical distribution theory and comprises the study, development and expansion of distributions, and the addressing of parametric statistical inferential aspects, within the classical as well as the Bayesian framework. She is the academic research leader of the Statistical Theory and Applied Statistics focus area within the Department of Science and Technology/ National Research Foundation (DST-NRF) Centre of Excellence in Mathematical and Statistical Sciences, as well as  an elected member of the International Statistical Institute. Dr. Bekker has published more than 70 peer-reviewed papers in fundamental statistical research.
Dr. Ding-Geng Chen is a fellow of American Statistical Association and currently the Wallace Kuralt distinguished professor at the University of North Carolina at Chapel Hill as well as the South Africa DST-NRF-SAMRC, SARCh I in Biostatistics (Tier 1). He was a professor in biostatistics at the University of Rochester and the Karl E. Peace endowed eminent scholar chair in biostatistics at Georgia Southern University. He is also a senior statistics consultant for biopharmaceuticals and government agencies with extensive expertise in Monte-Carlo simulations, clinical trial biostatistics and public health statistics. Dr. Chen has more than 150 referred professional publications and co-authored and co-edited twenty-three books on clinical trial methodology, meta-analysis and public health applications. He has been invited nationally and internationally to give speeches on his research.
Dr. Johan Ferreira is currently a senior lecturer in the Department of Statistics at the University of Pretoria, South Africa, and is Junior Focus Area Coordinator for the Statistical Theory and Applied Statistics focus area ofthe Centre of Excellence in Mathematical and Statistical Science based at the University of the Witwatersrand in Johannesburg.
