Team: Energy balance and obesity
University Teacher- Researcher  |  Professor - PhD  |  Université de Bordeaux

My current research aims to decipher the effects of nutrients on microglial energy metabolism in the context of obesity. This follows on from my initial work (2001-2010) on the role of microglial inflammatory activation in various pathophysiological contexts. This project also builds on the expertise acquired between 2011 and 2020 on the impact of nutrition on microglia/neuron interactions in healthy or diseased brain.
