Introductie

I started my scientific training at the University of Grenoble (France) with a Master’s degree in Exercise Physiology and Bioenergetics, followed by a PhD internship in the group of Pr. dr. X. Leverve (LBFA, University of Grenoble, France) where I studied the mechanisms of action of the antidiabetic drug metformin. After graduating, I joined one of the European leading group in the field of AMPK signalling and intermediary metabolism at the de Duve Institute (Pr. dr. L. Hue, Brussels, Belgium). Supported by a Michel de Visscher Research Fellowship, I studied the role of AMPK in the control of hepatic glucose metabolism and mitochondrial oxidative phosphorylation. In 2007, I moved to the Netherlands and joined the department of Molecular Cell Biology of the Leiden University Medical Center for driving several research projects aiming to identify novel therapeutic strategies for metabolic disorders. From 2010, I am one of the PI of the Diabetes group, in the MCB section ‘Aging and Signal Transduction’ of Prof. dr. Peter ten Dijke. Since 2012, I’m also appointed as Assistant Professor at the Leiden Parasite Immunology Group, headed by Prof. dr. Maria Yazdanbakhsh, where I’m currently developing a new research line at the interface between immunology and metabolism .
