Profile

Dr Iain Perkes is a Child, Adolescent, and Adult Psychiatry fellow at Royal Prince Alfred Hospital and The Sydney Children’s Hospital Network. He is a Clinical Lecturer at The University of Sydney and Associate Investigator at the Australian Research Council Centre of Excellence in Cognition and its Disorders.

Dr Perkes’ clinical interests include neurodevelopmental disorders such as obsessive-compulsive disorder, attention deficit hyperactivity disorder, and tic disorders. His laboratory interests are behavioural neuroscience and imaging. These interests coalesce in the use of functional magnetic resonance imaging and diffusion tensor imaging to investigate decisionmaking in childhood basal ganglia disorders. His Honours thesis work (‘Dysautonomia after traumatic brain injury: A novel quantitative method of assessment’) culminated in his co-founding and steering an international group to the publication of consensus definition, diagnosis, and measurement of autonomic complications after acquired brain injury.

Dr Perkes' interests in the taxonomy has shifted into transdiagnostic characterisation of behaviour and brain circuits of decision-making in neurodevelopmental disorders. Awards for this recent work include a NSW Institute of Psychiatry Fellowship and recognition by the Helmut Remschmidt Research Seminar Fellowship and the Society of Biological Psychiatry.
