My research interests are around alcohol, tobacco and other drug use and in particular how these relate to mental health disorders. I am also interested in the development of new treatment interventions, delivery of interventions to new groups and the use of new modes of delivery. I have used existing datasets including the WA Data Linkage System, to assess the long-term relationships between substance use mental / physical health disorders and self-harm behaviours. This work has included those in the general population, high-risk groups and clinical samples.
