Research interests

My broad research interest is studying evidence-based methods of assessment and treatment for psychopathology across the lifespan. My current research focus is on hoarding disorder in older adults. Hoarding disorder has historically been categorized as an obsessive-compulsive disorder with its etiological roots based in avoidance of anxiety. However, recent research suggests that not all hoarding is fear-based, and this may be particularly true for older adults. My lab is currently working on several projects to disentangle the etiological factors at play in the development and maintenance of hoarding disorder.
