The central focus of my research is mental health and addictions, with a particular emphasis on psychosis and the medications used in its treatment. My research program is based on a multidisciplinary and translational approach that spans from "bench to bedside," as I maintain strong and highly productive research programs in both clinical and related preclinical research.
Working in collaboration with some of Canada's finest researchers, I study "psychosis" from three different perspectives. These include idiopathic schizophrenia-spectrum disorders, psychostimulant drug-induced psychosis and (most recently) the post-operative delirium that occurs following cardiac surgery. Despite different etiologies and patient populations, these three conditions share many similarities in terms of symptoms and treatment, and all can be studied in a translational manner
