I am a clinical triallist and epidemiologist specialising in sleep and sleep disorders at the Woolcock Institute for Medical Research and the Macquarie University Department of Health Sciences. I use a wide variety of epidemiological research methods and designs including randomised controlled trials and population-based cohorts, including the Busselton Health Study. My colleagues and I are attempting to measure the impact of disease, the effectiveness of a variety of treatments and investigate health system activity related to sleep. I provide high-quality evidence-based information of direct and immediate utility to both practicing clinicians and policy-makers.
