Jennifer D. Ryan, Ph.D.
Anne and Max Tanenbaum Chair in Cognitive Neuroscience
Senior Scientist | Rotman Research Institute
Professor, Department of Psychology, Psychiatry | University of Toronto
Jen received her B.S. (1997) and Ph.D. (2001) in Psychology at the University of Illinois in Urbana-Champaign. She joined the faculty of the Rotman Research Institute (RRI) at Baycrest and the Department of Psychology at the University of Toronto in 2001.
She was promoted to Senior Scientist at the RRI in 2008, and Full Professor at U of T in 2014. Jen was awarded a Tier II Canada Research Chair in Cognitive Neuroscience (2006-2016). She recently served as the Director, Scientific and Academic Affairs, at the RRI (2017-2021) and held the accompanying chair, the Reva James Leeds Chair in Neuroscience and Research Leadership.
Jen’s research focuses on the nature of memory. Her work describes the types of memory representations that are formed by different regions of the brain, and how memories are used, in the moment, to influence ongoing exploration and cognition. Her research also investigates learning strategies that may alleviate or circumvent memory deficits in older adults and in cases of amnesia. Jen’s research examines memory using a converging methodologies approach, employing behavioural paradigms, eyetracking, neuroimaging (e.g., MEG, fMRI), and computational modelling, in order to comprehensively address the questions at hand.
Outside of science, Jen has a variety of interests. Throughout her life, she has participated in sports and endurance events (including track-and-field, cross country, basketball, court volleyball, and even rugby and GORUCK) to varying degrees of success, but always with an eye towards learning from the experience. She now regularly plays 2-on-2 women’s beach volleyball, and can occasionally be spotted running along the lakefront in Toronto. You can also find Jen on the Peloton and Concept2 leaderboards. She is a avid supporter of music, theatre, and the arts, and also enjoys reality tv and soap operas. During their respective seasons, you can hear Jen cheering loudly for the Toronto Raptors and Chicago Bears.
“If you ask me how I want to be remembered, it is as a winner. Is a winner somebody who has success and basically accomplished something or wins a game or whatever? That’s not a winner. You know what a winner is? A winner is somebody who has given his best effort, who has tried the hardest they possibly can, who has utilized every ounce of energy and strength within them to accomplish something. It doesn’t mean they accomplished it or failed, it means that they’ve given it their best. That’s a winner. That is what a winner is all about."

Hannah is a PhD student at University of Toronto with Dr. Jennifer Ryan and Dr. Asaf Gilboa. They completed their BSc at University of Saskatchewan, exploring the impact having conscious awareness of a stressor has on cellular memory mechanisms. For their MA, completed at the University of Toronto, they developed a model of learning based on principles of Bayesian statistics. For their PhD, they are studying how experiencing trauma can influence one's ability to imagine new experiences. Their current research uses eye-tracking and neuroimaging to explore these differences in individuals with post-traumatic stress disorder in hopes of better understanding the mechanism of a current treatment called eye-movement desensitization and reprocessing therapy.

-
Negar is a graduate student in the Department of Psychology at the University of Toronto. She is co-supervised by Dr. Jennifer Ryan and Dr. Rosanna Olsen. She completed her HBSc in Psychology at York University. Some of her undergraduate research in cognitive neuroscience involved delivering cognitive interventions to patients with dementia in order to investigate effects on memory, as well as exploring the neuroscience of learning and memory among younger and older adults. For her graduate research, she is interested in examining the structural and functional brain changes that occur as a result of neuropsychological conditions (e.g., Alzheimer's disease) and aging. Moreover, her work utilizes eye-tracking and neuroimaging techniques to explore the relationship between memory and visual exploration among younger and older adults.
Erik Wing
POSTDOC
ewing@research.baycrest.org
-
Erik moved to Toronto to do postdoctoral research with Jennifer Ryan and Asaf Gilboa after completing his PhD at Duke University, where he worked with Roberto Cabeza. He is broadly interested in various factors that influence learning, as can be seen when information is differentially prioritized, distorted, or schematized. His current research focuses on how having organized knowledge about a particular domain (anything from art history to cars) influences learning and memory for related material. This process is familiar to anyone who initially struggles to learn unfamiliar information but finds that subsequent learning is easier once new material can be integrated into an emerging knowledge framework. With respect to brain function, he is interested in exploring how the acquisition of visosemantic expertise leads to reshaping of neural representations, with corresponding consequences for different forms of memory.

Jessica is a graduate student at the University of Toronto supervised by Dr. Jennifer Ryan. She completed her BA in Psychology at York University where she explored her research interests by working with populations across the lifespan. She later spent two years working as a lab manager in a lab focusing on infant pain. Ultimately, after exploration in research with both infants and adults, she was drawn toward research on memory and aging. Jessica is interested in psychosocial factors and their influence on memory, as well as developing strategies to improve memory functioning in older adults. For her graduate research, she is currently evaluating specific strategies and exploring how psychological disorders/symptoms affect the ability to use these strategies to improve memory.
