Introductie

Assistant Professor


Biography

My scientific training started 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. X. Leverve's lab 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 metabolism at the de Duve Institute (Pr. L. Hue, Brussels, Belgium) where I investigated the role of AMPK in the control of hepatic glucose metabolism and mitochondrial oxidative phosphorylation supported by a “Michel de Visscher” Research Fellowship. In 2007, I moved to the Netherlands and joined the Diabetes group of the department of Molecular Cell Biology of LUMC for driving several research lines aiming to identify novel therapeutic strategies for obesity and type 2 diabetes. Since 2012, I’m also appointed as Assistant Professor at the Leiden Immunoparasitology Group (LIPG) where I’m currently developing a new research line at the interface between immunology and metabolism.


Research interest

My main interest is currently focused on studying the molecular mechanisms underlying the immunometabolic effects of parasitic infection and parasite-derived molecules using both in vitro and in vivo approaches in various rodent models or in humans. This original research line is aimed to identify new metabolically-active molecules and/or potential novel molecular targets involved in tissue-specific regulation of substrate metabolism and insulin sensitivity that can ultimately lead to future therapeutic opportunities for the treatment of metabolic disorders and type 2 diabetes.

Current research support

  • Grant from European Association for the Study of Diabetes on the project: ‘Protective effects of parasite-derived molecules in metabolic disorders.’
  • Co-applicant on a grant from Netherlands Royal Academy of Science and Arts (KNAW) on the project: ‘Helminth infections and type 2 diabetes mellitus in Indonesia. Integrating parasitological, immunological, behavioral and metabolic studies.’ Main applicant Prof. Dr. J.W.A. Smit.
  • Co-applicant on a TopGrant grant from ZonMW on the project: ‘Helminth-derived glycoproteins and insulin sensitivity: from immunomodulatory properties to direct regulation of metabolic tissues.’ Main applicant Prof. Dr. M. Yazdanbakhsh.
