Arul is currently working as a Principal Medical Statistician in a hospital in Singapore as well as an adjunct senior lecturer (biostatistics) with the University of Sydney, Arul works with researchers from various backgrounds, including health services research, health workforce and spatial epidemiology. His present research interest is in Bayesian spatio-temporal models, including ways to improve current forecasting techniques. This involves using spatial analytic tools to analyse data aggregated at an areal level. He has developed and applied some Bayesian spatio-temporal models to study and understand the relationship between geographically correlated variables such as socio-economic status and levels of remoteness to heart disease admissions and procedures in New South Wales. He is one of very few biostatisticians in Australia who is working actively in this area. Arul is also a chief investigator of an ARC linkage grant worth around $717,000. The aim of that project is to study the economic impacts of disease on older workers and to examine costs to government and individuals and identify opportunities for intervention. [More...]

Arul has experience in conducting talks on biostatistics and he enjoys conducting classes on the use of statistical software. More recently, he has organised the inaugural Northern Rivers Postgraduate Symposium in December 2006. He was in the organising committee of the International Society for Bayesian Analysis 9th World Meeting, which was held in Hamilton Island, Australia in July 2008. These meetings are held bi-annually, with only alternate events being staged outside Spain and they are considered to be the premier event on the Bayesian calendar.

For the past six years, Arul has provided consultative and collaborative methodological input to clinicians, public health specialists, government and hospital administrators. The outcome for some of this work has been more than 50 publications in a variety of peer-reviewed international medical journals, including BMC Health Services Research, BMJ and JAMA. He has also reviewed several journal articles for JAMA and BMC Health Services Research, and the Journal of Urban Health. Arul obtained his MSc in Medical Statistics from the London School of Hygiene and Tropical Medicine in the United Kingdom in 2002. He has also received the prestigious status of a Chartered Statistician (C.Stat) with the Royal Statistical Society in London at a relatively early stage of his career. This is the Society's highest professional award and it provides formal recognition of an individual's statistical qualifications and professional training and experience.
