Dr. Leduc-Gaudet is an Assistant Professor in the Medical Biology Department at Université du Québec à Trois-Rivières (UQTR). He completed his bachelor in Kinesiology and his master degree with a particular focus on mitochondrial biology, skeletal pathophysiology and aging at Université du Québec à Montréal. Following his M.Sc., he completed his Ph.D. studying the regulatory roles of autophagy & mitophagy in the maintenance of skeletal muscle health under the supervision of Drs. Hussain and Gouspillou (McGill University), where he received a Vanier Canada Graduate Scholarship. After completion of his Ph.D. in 2020, Dr. Leduc-Gaudet completed a postdoctoral fellow in Dr. Sandri’s lab (U Padova, Italy), working on characterizing novel genes and molecular pathways that control skeletal muscle health. In 2023, Dr. Leduc-Gaudet opened his own lab at UQTR to study novel genes and molecular pathways that affect skeletal muscle health, whole-body metabolism, and longevity. Dr. Leduc-Gaudet research program at UQTR also investigates how dysregulated mitochondrial quality control can be harmful to muscle cells. Indeed, mitochondrial dysfunction is a common underlying feature of many muscle-wasting conditions, including aging and neuromuscular diseases. In his research, Dr. Leduc-Gaudet combines genetic, molecular, cellular and physiological approaches to investigate signalling pathways regulating skeletal muscle mass and function.
