The objective of my research is to improve understanding of the genetic etiology and biological mechanisms underlying risk of common psychiatric disorders, particularly those with onset during childhood and adolescence. As a Senior Research Fellow at the Child Health Research Centre, I lead a number of domestic and international collaborations that evaluate the association between polygenic risk scores, environmental variables and behaviour during childhood and adolescence. My group applies innovative statistical methods to large longitudinal datasets with information from infancy through to adulthood and to evaluate genetic and environmental contributions to risk to mental health problems. In addition, our research focuses on the potential clinical utility of polygenic risk scores in psychiatry. I have contributed to major advances in understanding of the etiology of a number of psychiatric disorders, with a major focus on depression
