Biographical Information

I obtained my first degree, a double first in Chemistry from the University of Cambridge, in 1965 and a Ph.D. in Inorganic Chemistry from UNISA in 1970. I worked in Chemistry at the NCRL, CSIR, in Pretoria from 1967 to 1971 and lectured in Chemistry at the Medical School at UCT in 1975. I began my career in Statistics, studying through UNISA while my children were small.

I joined the Department of Statistics and Biometry at the University of Natal in 1978 as a Lecturer and was promoted to Senior Lecturer in 1984, Associate Professor in 1994 and full Professor in 1998. I was appointed as Full Professor in the Department of Statistical Sciences at UCT in 2005 and moved down to Cape Town in January of that year. I have spent sabbatical leave at the University of Cambridge in the U.K. and at the Universities of North Carolina, Purdue and Ohio State in the USA. I have been involved in various activities in the Statistical community both nationally and internationally.

In particular I am a past-President of the South African Statistical Association and have served on a number of committees at the NRF. I also served on the Program Committee of the International Workshop in Statistical Modelling in 2006 and of the International Biometrics Conference in 2008. I was an Associate Editor for Statistical Modelling and for the Journal of Statistical Planning and Inference for many years and currently contribute to Maths Reviews. I have supervised 25 Masters and 3 doctoral theses and am currently co-supervising 1 Ph.D. student and 1 Masters student. I was invited to participate in the program on the Design and Analysis of Experiments at the Isaac Newton Institute for Mathematical Sciences at the University of Cambridge in 2011 and spent two months there. I will be returning to the Institute for a one-week follow-on meeting on Design and Analysis of Experiments in Healthcare Design in 2015.

Research Interests

The focus of my research is on design of experiments for linear and nonlinear models and on statistical modelling. In addition I am involved in a miscellany of applied projects.

Postgraduate Projects

I retired at the end of 2009. However I am happy to co-supervise any post-graduate students interested in research in the areas of optimal experimental design and spatial statisics. I am currently working on optimal designs for applications in the chemical industry with Dr Roelof Coetzer of SASOL, on spatial statistics with Professor Christien Thiart here at UCT and on designs for microarray analysis with Dr Legesse Debusho of the University of Pretoria.
