My research focuses on the causes, treatment and prevention of depression and anxiety. I also investigate self-harm and suicidality, which frequently occur with depression and anxiety. These mental health problems often begin during adolescence and much of my research focuses on young people. 

I am funded by a Wellcome Trust Sir Henry Dale fellowship. My fellowship is investigating the potential role of academic pressure during secondary school in the development of adolescent depression, anxiety, self-harm and suicide.

I use large population-based cohorts, electronic health records, and causal inference methods to inform prevention. I also analyse data from large randomized controlled trials, to improve treatment.
