Sharlene Kaye is a Senior Research and Evaluation Officer at the Research and Evaluation Service, Justice Health and Forensic Mental Health Network, and is a Conjoint Senior Lecturer at NDARC. She has worked on several NDARC projects, including a major study of Antisocial Personality Disorder among injecting drug users and the Illicit Drug Reporting System. She completed her PhD at NDARC in 2003 which examined the patterns and harms of cocaine use. Sharlene has worked on studies examining fatal and non-fatal cocaine overdose, psychostimulant-related deaths across Australia, and organic brain damage following opioid overdose. She has also completed an investigation into the diversion and misuse of stimulant medication for ADHD among illicit psychostimulant users and, in collaboration with colleagues from the University of Qld and Deakin University, is conducting a study of the non-medical use of prescription stimulants among Australian university students. Her interest in the comorbidity between ADHD and substance use has led to her current involvement in two international multi-site studies of the prevalence and correlates of ADHD among people with substance use disorders and she is a board member of the International Collaboration on ADHD and Substance Abuse (ICASA). Sharlene is currently involved in the Network Patient Health Survey which is comprised of the Adult Patient Health Survey, the Young People in Custody Survey and the Forensic Mental Health Patient Survey.
