Hervé obtained his PhD in 2004 in Rennes (Agrocampus Ouest, supervision by Pr Legrand and Dr D'Andrea). There, he studied a critical gene in fatty acid metabolism (FADS2) through cellular biology and biochimical approaches. Then, for three years he has been a post-doctoral scientist in Dr Len Stephens and Dr Phill Hawkins' group (Babraham Institute, Cambridge, UK) where he worked on PI3-Kinase signalling. He joined the Integrative Toxicology and Metabolism group in 2008. His work in the group aims at developing approaches that could allow a better understanding of how changes in hepatic lipid metabolism may result from or influence endocrine disruption.

Laurence Gamet - Payrastre - senior researcher - Her researches are focused on the impact of chronic exposure to low doses of pesticide mixture. She coordinated two research projects between 2008 and 2012 supported by ANR and ANSES focused on the impact of pesticides mixtures at low doses on various physiological functions and on the characterization of such an exposure using metabonomics approach; she worked in collaboration with internal INRA teams, and with INSERM U563 and Neuroservice. She was involved in the INSERM collective expertise (report published in 2013) on the impact of pesticides on health. She is a member of the Anses expert committee on Biocides toxicity. She has directed two expertise elected by COSMAP (Ministry of Agriculture, food and forestry ) in collaboration with the University of Louvain (Belgium) (Identification of pesticides involved in the occurrence of leukemia in adults occupationally exposed -Bibliographic review on the impact of pesticides mixtures).

Nicolas, an organic chemist by training, did a thesis at CEA Saclay under the supervision of Pr M. Delaforge at the interface of Chemistry, Hepatic Metabolism and Molecular Modeling of interactions between contaminants and membrane proteins. He was recruited at INRA in 2002 as CR2 to study the fate of mycotoxins in livestock. In order to deepen his knowledge on sphingolipid metabolism, Nicolas chose to do a post-doctoral period in the Dermatology research unit of the VA Medical Center in San Francisco (Dr. Uchida Y. and Pr Holleran W. team) where he studied the sphingolipid composition of the Stratum Corneum and their implications in Gaucher's disease, Harlequin Ichthyosis and Atopic Dermatitis Upon his return from his post-doctoral studies, Nicolas joined the Integrative Toxicology and Metabolism team in order to develop toxicology projects integrating lipidomics and transcriptomics approaches. His current research project focuses on the impact of contaminants and environmental factors on hepatic metabolism.

Sandrine did her PhD in molecular toxicology at INSERM, University Paris 5, under the supervision of Dr. I. de Waziers, between 2006 and 2010. She investigated the molecular consequences of the exposure of human adipose tissue to various environmental polluants, using ex-vivo adipose tissue models and “omics” technologies (transcriptomics, metabolomics). From 2010 until 2013, she did her post-doc at the Netherlands Metabolomics Center in collaboration with Pr. T. Hankemeier at Leiden University, investigating pharmaco-metabolomics. In collaboration with the Pharmacometabolomics Research Network (Duke University), she aimed at determining the metabolic determinants of the variation of response to anti platelet drugs. Since 2014, she works at INRA and is interested in the interactions between food contaminants and gut microbiota.

Hervé, University Professor, is interested in the development of hepatic steatosis in overfed palmipeds. Hervé first carried out numerous studies on muscle development and poultry meat quality at INRA Tours-Nouzilly, then at the UMR INRA-INP/ENSAT Tandem. Since the beginning of 2010, he has been interested in the development of hepatic steatosis in fatty palmipeds, first within the UMR INRA-INP/ENSAT-ENVT GenPhySE and joined the TIM-ToxAlim team at the beginning of 2021. In parallel to his research work, Hervé REMIGNON teaches animal sciences at INP-ENSAT where he has also previously held numerous administrative responsibilities. He regularly carries out evaluation missions of higher education institutions on behalf of the HCERES.

Anne completed her PhD at the Toulouse Purpan Physiopathology Center (INSERM U563, CPTP, Toulouse) under the supervision of Dr Muriel Laffargue during which I studied the role of phosphoinositide 3-kinase gamma (PI3Kγ) dependent signaling in arterial pathologies, particularly atherosclerosis and its complications. She then completed her first post-doctoral fellowship in the team of Dr. Alexey Pshezhetsky at the CHU Sainte-Justine Research Center in Montreal where she worked on the regulation of insulin signaling by neuraminidases. Since 2017, Anne joined the TIM team to perform a second post-doc and obtained in 2018 an Agreenskills funding. Her project consisted in better understanding the transcriptional control of ketogenesis and hepatokine FGF21, two vital functions performed by the liver. Anne was recruited to the team in September 2021 and is currently developing a project combining in vitro and in vivo approaches to study the hepatic and systemic effects of dietary nutrients and contaminants and to identify the mechanisms involved.

Elisa, Professor of Toxicology, prepared a thesis in pharmaco-toxicology of G-protein coupled receptors, within Pierre Fabre Laboratories. After a post-doctorate at Inserm (Laboratory of Biology and Digestive Pathology) and a temporal position as associate Professor, Elisa was recruited as a lecturer in Toxicology in 2005 at Toulouse University-Faculty of Pharmacy. She first worked in epidemiology and public health, in collaboration with the Institute of Public Health, Epidemiology and Development (ISPED) of Bordeaux in the context of occupational exposure to pesticides. In order to develop molecular epidemiology projects, Elisa joined the team of Bernard Salles at IPBS (Institute of Pharmacology and Structural Biology of Toulouse) and ToxAlim in 2011, where she first studied pesticides and their ability to generate DNA damage in farmers' cohorts. She has diversified her research by studying the genotoxicity of pesticides and other contaminants on relevant experimental cellular models in the context of xenobiotics exposure. Elisa joined the TIM team in early 2022. She is notably developing a project there on the toxicity of pesticides, with a collaboration with the CRCT (Toulouse Cancer Research Center).
