My research is focused on understanding the processes involved in the development of mental illness. Using a combination of epidemiological, genetic, and machine learning techniques, I strive to elucidate the interplay between different risk and protective factors for mental health difficulties. I am currently investigating factors which might be protective against adolescent suicidal ideation/self-harm following exposure to adverse childhood experiences.Ìý
