Sandhya is the Research manager for the Dunedin Multidisciplinary Health and Development Study. Her role includes research administrative support to the Director and to the Dunedin Study Theme leaders, as well as the management of the assessment phases of the Dunedin Study. She has previously worked as a clinical psychologist in the New South Wales Department of Corrective Services in Australia.
Research Interests
Sandhya's PhD used Dunedin Study data to examine the links between mental and sexual health, with specific reference to risky sexual behaviour. Her current research interest involves examining the mental health and psychosocial correlates and consequences of skin conditions.
