Dr. Rodrigue Brossaud | Gastrointestinal Pharmacology | Best Researcher Award
McMaster University | Canada
Dr. Rodrigue Brossaud is a distinguished neuroscientist and postdoctoral fellow specializing in neurogastroenterology at McMaster University in Canada, working under the guidance of Dr. Elyanne Ratcliffe at the Farncombe Institute. Supported by a prestigious DeGroote Postdoctoral Award, his research explores how prenatal cannabis exposure influences the development of the microbiota–gut–brain axis, emphasizing the pivotal role of the endocannabinoid system in the maturation of both the enteric and central nervous systems. His work bridges developmental neurobiology, microbiome science, and neuropharmacology, offering groundbreaking insight into how early-life environmental exposures can shape lifelong neurological and gastrointestinal health.Dr. Brossaud earned his Ph.D. in Neuroscience from Nantes University, where his doctoral research in the TENS Laboratory at the Faculty of Medicine, under the mentorship of Prof. Michel Neunlist and Dr. Moustapha Cissé, focused on the beneficial effects of bacterial metabolites on early intestinal amyloid pathology in a mouse model of Alzheimer’s disease. His findings highlighted the therapeutic potential of gut-derived microbial compounds in modulating neuroinflammation and amyloid accumulation, laying the groundwork for novel microbiota-based strategies in neurodegenerative disease management.Before his doctorate, he completed a Master’s in Biology, Biotechnology, and Therapeutic Research at Nantes University with honors, conducting an advanced study on the role of interactions between CD4 T cells and enteric glial cells in early relapses of Crohn’s disease, supervised by Prof. Philippe Naveilhan. His bachelor’s degree in Animal Physiology and Cellular Biology, also earned with honors, and his intensive preparatory studies in Biology, Chemistry, Physics, and Earth Sciences at Georges Clemenceau High School, further strengthened his multidisciplinary scientific foundation.
