Gareth James is an expert on statistical methodology with particular application to marketing problems such as prediction of technology evolution. He has published over 20 articles in leading journals such as the Journal of the American Statistical Association, for which he also serves on the editorial review board. He teaches both MBA and PhD courses ranging from introductory statistics through to advanced modern non-linear regression techniques. Professor James has won several recent research and teaching awards, including the Deans award for Research Excellence and two Golden Apple awards for his MBA courses.
