the University of Natal, Pietermaritzburg, where he had been lecturing
since 1975. Earlier, he had trained as a schoolteacher and taught at
Pietermaritzburg College in 1974. From mid-1985 to mid-1987, he was on

(1976) and BSc Hons (Statistics) (1978) from the University of Natal,
Pietermaritzburg, and a PhD (1982):
Contributions to the theory of generalized inverses, the linear model
and outliers, from UCT.
He served as President of the South African Statistical Association in
1992/93 and has been editor of the Association's newsletter. In December
1996 he organised ISBA96, the 4th World Meeting of the International
Society for Bayesian Analysis. He has been National Secretary of the
South Africa Group of the International Biometric Society, and was
conference organiser of the International Biometric Congress IBC98 in
Cape Town. He is on the Council of the International Statistical
Institute (2007-2011), and served as the Chair of the Local Programme
Committee for the 57th ISI Session in Durban, South Africa,
during August 2009. In addition, he has been a member of the American
Statistical Association, the Royal Statistical Society, the

College House, one of UCT's student residences from 1985 to 1994.
He is currently Chair of the UCT Senate Committee for Ethics in Research
(2009-2011).
Research Interests
Tim Dunne's original research interests lay in aspects of the general
linear model such as the consideration of outliers, influence,
covariance structures, robust estimation and diagnostics. He
collaborated on these projects with Prof Robert Schall, University of
the Free State. Bloemfontein, formerly of the Institute for
Biostatistics, Medical Research Council. Currently, he has interests in
the development of applied statistics, especially methods relevant to
problems in education, medicine and psychology.
Legal and Forensic Statistics
Tim Dunne has given expert opinion on statistical issues in two criminal
trials and in three civil actions. The opinions in criminal cases
centred on the enumeration of possibilities, and calculation of
probabilities, when blood stains arise from more than one source. One
civil action concerned issues of data ownership, and suppression of
information. Another civil action was a matter brought to the Courts by
commuters against the Metrorail company, seeking a ruling on the
adequacy of its safety policies and public protection from crime. The
commuters eventually had their rights vindicated by the Constitutional
Court. In the third matter, there is contending scientific opinion
before the Court on the causal initiation of disease in pineapple
farming.
Consultation and National activities
Tim Dunne has served as a consultant to the Western Cape Education
Department (WCED), and is a member of the Statistics and Assessment
Committee of UMALUSI, the body which certifies the national
school-leaving examinations. He serves within the RCI programme of
SANPAD to develop statistical skills in post-graduate students,
particularly in the social sciences and humanities (2005-2013). Other
activities have included service to the SA Institute for Drug Free Sport
(SIDFS), and to the Joint Education Trust (JET). He has consulted on
survey design and methodology, and medical trials and experiments, and
in a wide array of educational contexts. He served as a co-editor
(2006-2009) of the South African Statistical Journal (SASJ), and is
currently on the Editorial Board of the Journal of Applied Statistics.
Thesis supervision
Tim Dunne has supervised the PhD theses of Robert Schall, Christien
Thiart, Daniel Polakow, Barbara Paterson and Freedom Gumedze in
Statistical Sciences, and the theses of Martin Fisher, Nan Yeld and
Heidi Bolton in Education. He has supervised various MSc and MEd
students. His current PhD students are Anna Crowe, Caroline Long and
Surette van Staden (UP).
