Professor Adrian Esterman, University of South Australia

All welcome!

Many an NHMRC grant application has floundered due to incorrect power analysis. Yet, to many researchers, sample size calculations are a total mystery - indeed an art form, created by biostatisticians waving a magic wand over study proposals. To some extent this stereotype is justified, since sample size calculations are replete with
guestimates and approximations. Further, for many of the more advanced statistical models, suitable software is simply not available, and approximations and rules of thumb are all that is possible.

In this talk, Professor Esterman will attempt to demystify sample size calculations, and will point out what you can do yourself and more importantly, when you should be seeking help.

Professor Esterman holds the Chair of Biostatistics at the University of South Australia and an has just been appointed adjunct professor in the JCU School of Public Health and Tropical Medicine. He initially trained in statistics at the University of Bath, UK, followed by a Masters degree in medical statistics at the London School of Hygiene
and Tropical Medicine, and finally a PhD in epidemiology at Flinders University. He has nearly 40 years of experience as a biostatistical and epidemiological consultant.

His career includes seven years as a WHO staff member based in Geneva and Copenhagen and 14 years as a Principal Epidemiologist with the South Australian government. He is a Chief Investigator on several million of competitive grants, is a member of the editorial board of three scientific journals and is a statistical reviewer
for many others. He has an h-index of 33 with over 200 publications.
