Biography:

 

Marie-Ève Tremblay is a Canadian neuroscientist, researcher and academic at the University of Victoria. She obtained her Ph.D. in 2009 when microglia, resident immune cells of the brain, were thought to be resting or quiescent in the absence of pathological challenge. Her research has stimulated a paradigm shift in neuroimmunology by revealing that microglia are always active, in health and disease, critical to maintaining brain health across life. This research has involved the supervision of over 125 undergraduate and graduate students, postdoctoral fellows, and research assistants or associates. Dr. Tremblay has been invited to present her research findings over 200 times in seminars, symposia, specialized courses and workshops, with a majority (75%) on the international level. She has over 250 publications, excluding preprints, cited over 23,000 times (Google Scholar). In 2021, 2022, 2023, 2024, and 2025, Clarivate ranked her among the top 1% of most highly cited researchers across fields. Expertscape also ranked her 3rd and 4th in the world and 1st in Canada for her microglial expertise. She is the Tier 1 Canada Research Chair in Neurobiology of Healthy Cognitive Aging and an Elected College Member of the Royal Society of Canada, Editor-in-Chief of the Glial Health Research journal published by Elsevier, and former Specialty Chief Editor of the Non-Neuronal Cells section of Frontiers in Cellular Neuroscience. Overall, Dr. Tremblay has sparked the development of a new and fast-growing field of research investigating the many roles of microglia in the healthy brain. With Dr. Tremblay’s research, notably, microglia have emerged as an important link between lifestyle elements, environmental risk factors and genetic variants driving disease onset and progression throughout life.
