I received my PhD from the University of Nice Sophia Antipolis, France in 2003 in the laboratory directed by Dr Paul A Grimaldi. As a student I published seminal papers showing the role of PPAR delta in the control of muscle development and oxidative capability, and developed a strong knowledge in peripheral tissue metabolism & insulin sensitivity. In 2003 I joined the laboratory of Professor Richard Palmiter (Howard Hughes Medical Institute & Department of Biochemistry) at the University of Washington. As a post-doc I focused primarily on the role of hypothalamic neurons that produce Agouti-related protein (AgRP) in the control of feeding behavior and further expanded my technical and conceptual skills in the field of molecular neuroendocrinology. I was recruited as an independent researcher by the French CNRS in 2006 and was awarded a young investigator research program where I now serve as group leader. Since 2009 my group is established at the University Paris 7-Paris Diderot.
My group (http://www.bfa.univ-paris-diderot.fr/spip.php?rubrique81) integrates the use of modern molecular genetic tools and mouse models to dissect the role of discrete neural circuit elements in the control of energy balance and the central basis of the metabolic syndrome. A recent achievement was to identify a novel role for a hypothalamic circuitry in AgRP-neurons in the coordination of efferent organ activity and nutrient partitioning, providing a mechanistic link between obesity and obesity-related disorders. In addition we recently demonstrated that when AgRP-neurons ‘activity is compromised through genetic, pharmacologic or dietary intervention (such as diet-induced obesity)-feeding behaviour is no longer dependent on metabolic demands but prominently rely on dopamine-encoded reward and leads to compulsive/comfort feeding. I have also developed unique technological approaches that will allow us to decipher the physiological basis of central lipid sensing. We demonstrate an unexpected role for brain lipid detection as possible mechanism for addictive-like behaviour associated with high fat diet.
I have successfully completed for a variety of funds, raising no less than 1.1 million euros in research contracts and grants since 2009. Although young, my group has already established strong national and international scientific networks based on our team’s recognition in the field of energy balance regulation.The techniques routinely used include viral-mediated genetic modification of brain nuclei, neurons-specific genetic disruption, in vivo indwelled chronic perfusion (carotid artery, jugular vein, intracerebroventricular), in vivo analysis of insulin sensitivity, microsurgery (catheter, cannula implant, vagal deafferentiation, bariatric surgery in mice), in vivo assessment of motivated behavior and positive reinforcement, in vivo assessment of metabolic efficiency and energy balance using fully automated and integrated indirect calorimetry (VO2, VCO2, RER), food intake & tropism, water intake, locomotor activity, telemetric recording of body temperature and cardiac rhythm, as well as tissue, feces & urine collection
