Prof Christel Middeldorp has a conjoint appointment with the Child Health Research Centre (CHRC), UQ, and Child and Youth Mental Health Service (CYMHS), Children’s Health Queensland Hospital and Health Service (CHQ HHS). Her research interests involve the role of genetic and other familial influences on the development and persistence of psychopathology across the lifespan. She is the co-PI of the Behavior&Cognition working group of the EAGLE consortium (EArly Genetics and Lifecourse Epidemiology). EAGLE aims to identify genetic variants underlying the development and persistence of childhood psychopathology by using data from population based longitudinal child and adolescent cohorts from over the world. She further investigates associations between parental and offspring psychopathology and the development of these associations over time in a clinical cohort consisting of families with children treated at outpatient psychiatric services, who are followed longitudinally.
