Earnest, Arul

Research Interests:

Arul’s current research interest is in Bayesian spatio-temporal models. He has developed and applied these models to study heart disease admissions as well as birth defect data in New South Wales, Australia, as well as mapping out-of-hospital cardiac arrests in Singapore. For more than 10 years, Arul has provided consultative and collaborative methodological input to clinicians and hospital administrators. The outcome for some of this work has been more than 85 publications in a variety of peer-reviewed international medical journals, including BMC Health Services Research, BMJ and JAMA, more than 100 presentations, as well as several research awards. Arul has secured several recent grants, including a large Australian ARC grant, as well as an NMRC grant from Singapore. He has extensive experience in conducting talks on biostatistics and research methodology. He regularly reviews articles for journals, including BMC Health Services Research and MJA.
