Afflicting one percent of the adult population with devastating hallucinations, delusions and social impairment, schizophrenia has long been known to have a genetic component. Ridha Joober, MD, PhD, joined the Douglas Institute in 1999 and has since made significant contributions in unveiling the genetic basis of schizophrenia and ADHD.

As a major research focus, Ridha Joober investigates the relationship between genetic variations and neuropsychological and behavioural traits in patients with schizophrenia and ADHD as well as the response of these disorders to pharmacological treatment. Ridha Joober's recent work has focused on the environmental factors involved in ADHD, particularly maternal smoking during pregnancy. This research has led to the development of more precise pharmacogenetic and environmental profiles of schizophrenia and ADHD that may ultimately lead to the earlier diagnosis and more effective treatment of these psychiatric disorders.

Throughout his career, Ridha Joober has received a number of awards and distinctions, including the 2002 Young Investigator Award from the Canadian Institutes of Health Research (CIHR), a Senior Research Scholar Award from the Fonds de recherche en santé du Québec (FRSQ), and the Sam Lal Award from the Graham Boekh Foundation and the Canadian College of Neuropsychopharmacology (CCNP).
