    Dr. Evelyn Stewart is an Associate Professor in the Department of Psychiatry, University of British Columbia and is the founding director of the Pediatric Obsessive-Compulsive Disorder Clinic and Research Program at BC Children and Women’s Health Centre. She is a clinical, genetic and neuroscience researcher, as well as a child and adult psychiatrist.

    Her research focuses on biologic, phenotypic, familial, and treatment aspects of childhood-onset neuropsychiatric disorders, such as obsessive-compulsive disorder (OCD). Dr. Stewart has authored over 70 original papers, reviews and chapters on genetic, clinical, and treatment aspects of OCD, Tourette's Disorder, and related illnesses. She sits on the Scientific and Clinical Advisory Board of the International OCD Foundation, on the Medical Advisory Board of the Tourette Syndrome Association and is Co-director of the International OCD Foundation Genetics Collaborative.

    Current Projects

    Neural Correlates in Childhood-onset OCD: The goal of this study is to evaluate for neurocognitive and neurosoft sign state and at-risk trait markers for OCD, by examining affected, at-risk and healthy youth.

    Brain Function and Structure in Pediatric Obsessive Compulsive Disorder: The goal of this study is to examine the cortical structure and functional activation in the regions implicated in OCD in OCD-affected, OCD-unaffected siblings, and healthy children and adolescents. A planning task conducted pre- and post-symptom provocation will be used to examine the impact of symptoms on executive function. In addition, DTI will record white matter structure and organization.

    As PI:

    • Obsessive-Compulsive Disorder (OCD) Registry and DNA Repository
    • Clinical Outcomes following Group-based Family Cognitive-Behaviour Therapy in Pediatric Obsessive- Compulsive Disorder (OCD).
    • Mindfulness Training versus Peer Support Groups for Parents of Obsessive-Compulsive Disorder
    • Objective measures of sleep and daily physical activity in pediatric Obsessive-Compulsive Disorder

    As Co-Investigator:

    • Cognitive and biological underpinnings of delusions in psychosis
    • Trends in Psychiatric Seasonal Emergency Admission

    1. 2014-2016, CIHR Operating Grant, $175,485/year ($526,454 for 3 years), Neural Correlates in Childhood-onset Obsessive-Compulsive Disorder. The goal is to compare neural correlates in CO-OCD and unaffected, at-risk sibling (SIB) groups with matched healthy controls (HC), in order to evaluate both their suitability as trait markers of genetic risk (to better understand the disorder) and their potential utility in clinical settings (to better manage the disorder). Role: Principal Investigator.
    2. 2014-2015, CIHR Planning Grant, $25,000 (total), Establishing a Pediatric Obsessive Compulsive Disorder Research Network. The goal is to rapidly establish the first formal Canadian national network dedicated to research on Pediatric OCD, with a central aim of partnering researchers, stakeholders and decision-makers who will set priorities and develop a research plan that contributes to knowledge creation and knowledge translation addressing health system deficiencies with respect to pediatric OCD. Role: Principal Investigator.
    3. 2012-2020, MSFHR Clinical Research Scholar Award, $90,000/year or ($635,000 for 8 years), OCD translational multi-modal research program. The goal is to create an interdisciplinary, multimodal research program within the new Pediatric OCD clinic at B.C. Children’s Hospital. Role: Principal Investigator.
    4. 2010-current, NIH-RO1, Perspectives on Neuroimaging and Genetics from Parents of Children with OCD. The goal is to examine experiences of parents involved in Pediatric neuroimaging studies. Role: Co-Investigator.
    5. 2007-2014, Obsessive-Compulsive Foundation Genetics Collaborative Whole Genome Association Study. The goal is to conduct a whole genome association study to genotype 1 million single nucleotide polymorphisms along the DNA of 2500 OCD cases and their parents or controls. This is the first study of its kind to be conducted in OCD. Role: Co-Principal Investigator.
