Jean-Leon Thomas

Jean-Leon Thomas is an Associate Professor in the Neurology Department at Yale School of Medicine, with additional affiliations at the Yale Stem Cell Center, Center for Brain & Mind Health, Vascular Biology and Therapeutics Program, Yale Cardiovascular Research Center, and Yale Ventures. His career spans from developmental biology research in France to his current neurovascular research at Yale.

Dr. Thomas earned his PhD from the University of Paris in 1992 and his MSc from the University of Nantes in 1981. His postgraduate work focused on glial cell development at INSERM, Salpêtrière Hospital in Paris, where he later became a Research Director in 2005. Prior to Yale, he served as Associate Professor at the University of Marne la Vallée since 1997 and led a research group on 'Oligodendrocyte development and Neurovascular interactions' at the Research Center of the Brain and Spinal Cord Institute.

His research centers on neurovascular interactions, meningeal lymphatic systems, and oligodendrocyte development. Current projects include Hox paralog group 2 genes in oligodendrocyte development and myelin repair (funded by ARSEP) and Neurogenesis through VEGF-C/VEGFR-3 signaling (funded by ANR). His work bridges cell differentiation, proliferation, neurogenesis, and stem cell biology with neurological disorders.

Analysis of his recent publications reveals a strong focus on the emerging field of meningeal lymphatics and the glymphatic system, particularly their roles in stroke, migraine, obesity-related neurological conditions, and brain clearance mechanisms. His research demonstrates how these systems interact with neural cells and influence neurological disease progression and recovery.

Dr. Thomas collaborates extensively with researchers including Anne Eichmann, Eric Hoyeon Song, Ligia Simoes Braga Boisserand, Akiko Iwasaki, and Helene Benveniste. His grant funding includes support from ARSEP and ANR for his current projects investigating oligodendrocyte development and VEGF-C signaling pathways.

His laboratory work focuses on neurovascular interactions, particularly examining how meningeal lymphatic vessels influence brain physiology, neuroinflammation, and neurological disorders. His team employs advanced imaging techniques to study CSF transport, glymphatic function, and their alterations in disease states.
