I’m a biostatistician in the Department of Epidemiology and Preventive Medicine at Monash University, in Melbourne, Australia, and I’m part of ViCBiostat: the Victorian Centre for Biostatistics. I’m the President of the Statistical Society of Australia, and am dedicated to ensuring that the statistical community in Australia is welcoming, respectful and inclusive.
My colleagues and I recently wrote about the importance of fostering biostatistics research for the success of research in health and medicine. Our article is freely available from the Medical Journal of Australia here.

Much of my recent work has focussed on the development of methodology for longitudinal cluster randomised trials, including the stepped wedge design and multi-cross-over cluster trial.
Many of my recent projects have been in the development of theory for causal inference.
I have been involved in several projects comparing the performance of healthcare providers.
