Biography:

Dr. Charles Gauthier earned his PhD in natural products chemistry from the Université du Québec à Chicoutimi (UQAC), followed by postdoctoral fellowships in carbohydrate chemistry at the Institut Pasteur in Paris and in chemobiology at the University of Oxford in United Kingdom. After a five-year tenure as a Senior Lecturer at the University of Poitiers in France, Dr. Gauthier joined the Centre Armand-Frappier Santé Biotechnologie of the Institut national de la recherche scientifique (INRS) in 2016 and was promoted to Full Professor in 2023. Since 2022, he has served as the co-director of the Unité mixte de recherche (UMR) INRS-UQAC.

Dr. Gauthier’s research program centers on the synthesis of microbial glycans for the development of prophylactic and therapeutic approaches. He has published >60 peer-reviewed papers and book chapters and supervised the work of >55 students, trainees, and postdocs. Dr. Gauthier’s research program has received funding from various granting agencies, including NSERC, CIHR, Pasteur Network, and NIH. Notably, Dr. Gauthier has been a recipient of FRQS salary support as both Junior 2 and Senior Scholar. Actively engaged in the academic community, Dr. Gauthier is a member of several national and international learned societies, including Oxford University’s VALIDATE network, GlycoNet, CRIPA, RISUQ, CISD, and CERMO-FC.
