Sheena Josselyn is a Senior Scientist at The Hospital for Sick Children (SickKids) and a Professor in the departments of Psychology and Physiology at the University of Toronto in Canada. She holds a Canada Research Chair in Brain Mechanisms underlying Memory, is a Senior Fellow in the Canadian Institute for Advanced Research (CIFAR), and is a Fellow of the Royal Society of Canada. 

Her undergraduate degrees and a master's degree in Clinical Psychology were granted by Queen’s University in Kingston (Canada). Sheena received a PhD in Neuroscience/Psychology from the University of Toronto with Dr. Franco Vaccarino as her supervisor. She conducted post-doctoral work with Dr. Mike Davis (Yale University) and Dr. Alcino Silva (UCLA). Dr. Josselyn received several awards, including the Innovations in Psychopharmacology Award from the Canadian College of Neuropsychopharmacology (CCNP) and the Effron Award from the American College of Neuropsychopharmacology (ACNP). 



Dr. Josselyn is interested in understanding how the brain encodes, stores and uses information. Several human disorders (ranging from autism spectrum disorder to Alzheimer’s disease) may stem from disrupted information processing. Therefore, this basic knowledge is not only critical for understanding normal brain function, but also vital for the development of new treatment strategies for these disorders.
