I have been Professor of Management (Statistics) at Melbourne Businss School since 2003. My research interests are in the analysis of categorical data, especially in classification methods, which have seen wide application in marketing research, and also in exact statistical methods, an area which has seen a recent resurgence of interest. My papers and articles have appeared in Journal of the American Statistical Association, Journal of the Royal Society and Strategic Management Journal. I am also the author of a graduate level textbook on categorical data analysis published by Wiley (1999). Prior to joining MBS, I held a number of other senior academic positions at institutions including the Australian Graduate School of Management, the University of Hong Kong, the University of Waterloo and London's Imperial College. I have consulted widely on behalf of the scientific community, as well as for several prominent legal firms. I was managing editor and joint theory and methods editor of the Australian and New Zealand Journal of Statistics from 2001-2005. (www.mbs.edu)
