Research Focus

My work focuses on qualitative aspects of memory representation and their neural correlates. More specifically, I am interested in the impact of pathology, aging and individual differences on memory qualities, and on the neural signature of memory retrieval. I completed a PhD in psychology under Dr. Morris Moscovitch and Dr. Mary Pat McAndrews at the University of Toronto. I assessed how medial temporal lobe structures contribute to the retrieval of perceptually rich autobiographical and laboratory memory episodes. My work combined behavioural and neuroimaging studies, and was conducted in a population of patients suffering from medial temporal lobe epilepsy recruited through the Epilepsy Clinic of Toronto Western Hospital. In collaboration with Dr. Cheryl Grady at the Rotman Research Institute, I also conducted neuroimaging work assessing how aging affects the neural correlates of different types of declarative memory retrieval. I am currently working as a post-doctoral fellow with Dr. Bradley Buchsbaum at the Rotman Research Institute. I am using functional MRI and multivariate pattern classification to assess how healthy aging, and individual differences in young adults, determine the similarity between the neural correlates of memory and perception. I hope to identify cognitive factors that predict the neural signature of memory retrieval, as well as testing conditions that favor the reduction of age and individual differences in memory representation.
