Research Interests

Olivia’s research interests include anxiety disorders and obsessive-compulsive and related disorders. For her masters thesis, she examined reassurance seeking behaviour in body dysmorphic disorder. For her future research, she is interested in examining racial-ethnic disparities in the assessment and treatment of anxiety and related disorders, as well as growing our understanding of the role of contextual variables (e.g., power, oppression) in how anxiety and related disorders develop and are expressed.

Clinical Interests

Olivia’s training has primarily been in cognitive behavioural therapy. She completed her first clinical practicum in 2019-2020 at the Psychology Training Clinic (Toronto Metropolitan University and St. Michael’s Hospital), and is now completing a practicum placement at the Frederick W. Thompson Anxiety Disorders Centre, Sunnybrook Health Sciences Centre. At these practica she has worked with individuals with OCD, various anxiety disorders, PTSD, and mood disorders. She has experience with mindfulness based therapies and is interested in furthering her clinical training in modalities such as emotion-focused therapy, acceptance and commitment therapy, and dialectical behaviour therapy.
