Keywords: psychopathology; cognitive processes; cognitive mechanisms; worry; anxiety
I received my PhD from Concordia University in 2007. During the final year of my doctoral training, I completed a clinical internship at the Centre for Addiction and Mental Health in Toronto. Following completion of the PhD, I joined Ryerson University as a postdoctoral fellow. I began my tenure-track faculty position at Ryerson in 2008 and have been a registered psychologist in Ontario since 2010.
My research interests are in the area of cognition and psychopathology with a specific focus on the ways in which concepts and methods from cognitive psychology can be used to inform and refine cognitive-behavioural theories and treatments for anxiety disorders. I am interested in various facets of cognition: cognitive structures (e.g., the organization and representation in memory of threat), cognitive processes (e.g., attention, appraisal, interpretation, problem-solving, reasoning) and self-reported thoughts and attitudes. Some areas of interest:
- Identification of cognitive markers of risk in individuals who are vulnerable to the development of an anxiety disorder. I am particularly interested in the causal role of information processing biases in anxiety;
Mechanisms of action in exposure-based treatments, in particular imaginal exposure; - Cognitive characteristics that distinguish individuals with generalized anxiety disorder from those with obsessive-compulsive disorder, with a specific focus on differences in the processing of uncertainty;
- Impact of cognitive training on anxiety and worry
At Ryerson University, I have taught courses on:
- Psychopathology (PSY325 Psychological Disorders, PSY905 Advanced Psychopathology Seminar, PS8301 Psychopathology, PS8707 Cognition and Psychopathology)
- Behaviour therapy (PSY806 Behaviour Modification)
- Cognitive psychology (PSY615 Psychology of Belief and Skepticism and CPSY308 Psychology of Thinking).
