I am a quantitative psychologist interested in understanding the course and interplay of multiple domains of mental health in young people. My work has shown how treatment-as-usual mental health services are associated with a subsequent reduction in adolescent depression. I am developing a comprehensive model of mental wellbeing and mental illness in young people across a suite of positive and negative emotional and behavioural symptoms. I am also modelling the interplay of harmful behaviours (NSSI, substance use, and antisocial behaviour) over adolescence and young adulthood, to identify high-risk groups based on these multiple behaviours. My work also seeks to understand the role of hormones in development, such as cortisol dysregulation in mental illness, and the influence of testosterone on behaviour. Such efforts aim to elucidate the aetiology of emerging mental health problems in young people and reveal targets for prevention and treatment.
