Dr. Tremblay’s research focuses on aging and cognition, using both animal and human brain models to explore the significance of microglial remodelling of neuronal circuits and elimination of synapses in the pathogenesis of brain disorders. She has developed state-of-the-art expertise in non-invasive imaging of the brain—combining chronic longitudinal two-photon in vivo imaging and correlative immunocytochemical electron microscopy with 3D reconstruction—to study the physiological roles of immune cells across the lifespan.

Dr. Tremblay came to the University of Victoria from the Université Laval in Quebec, where she was an Associate Professor in the Molecular Medicine Department. While at the Université Laval, Dr. Tremblay received a CIHR Foundation Scheme grant and a Canada Research Chair, Tier II in Neuroimmune Plasticity in Health and Therapy, among other impressive grants and awards. She has developed national and international prominence for her work, and has collaborated with many scientists. She also supports diversity and inclusivity, whether she is recruiting trainees or organizing events that include speaker panels.

Dr. Tremblay received her PhD in Sciences neurologiques at Université de Montréal in 2009. She was a Postdoctoral Fellow in the Department of Neurobiology and Anatomy and Center for Visual Science at the University of Rochester from 2009 – 2011 and in the Department of Psychiatry at the University of Wisconsin-Madison from 2011 – 2012.


A series of discoveries spanning the last decade has challenged our view of microglia, the resident immune cells of the brain, by showing their essential contribution to the experience-dependent remodelling of neuronal circuits. In this emerging field of investigation, Dr. Tremblay’s research program aims to determine –using a combination of non-invasive imaging techniques (electron microscopy with immunostaining and 3D-reconstruction, two-photon in vivo microscopy)– how this newly-defined basic mechanism could be implicated in the loss of synapses that best correlates with the impairment of learning and memory across chronic stress, depression, schizophrenia, aging, and neurodegenerative diseases.

At the University of Victoria, Dr. Tremblay plans to explore therapeutic interventions promoting resilience of the brain immune cells to stress that will, in turn, promote healthy cognitive aging and theoretically prevent related brain conditions through the maintenance of its complex circuitry and plasticity. Her research will have translational and biomarker development aspects that will serve well in creating potential collaborations with many researchers within the Division of Medical Sciences, as well as with researchers from other departments and institutions affiliated with the university.
