- Appointed as a permanent INSERM (NIH equivalent) researcher in 2001 at Grenoble.
- 2004: HDR diploma (Habilitation à diriger des recherches)
- 2004- 2010 at Grenoble: Work on mouse TCR genes using FISH techniques (unpublished), study of the role of Myocyte enhancer factor 2 (MEF2) in macrophage differentiation and c-Jun regulation, study on nuclear damages in macrophages infected by the opportunistic pathogen Pseudomonas aeruginosa.
- Since 2010, joined the Research Institute in Technologies and Sciences for Biology (iRTSV) at the CEA-Grenoble, Inserm unit 1038 "Biologie à Grande Echelle" (large scale biology). Dir. J. Garin and X. Gidrol. Our "Biomics" team is generally involved in fonctional and large scale siRNA screenings. I do work on histone H2AX phosphorylation in the context of nuclear damages following gamma-irradiation or upon infection by the opportunistic pathogen P. aeruginosa. In collaboration with microbiologists, we have shown that P. aeruginosa induces DNA double-strand breaks in infected cells and activation of DNA damage signaling and repair pathways (H2AX, ATM, 53BP1).
As pathogenic Escherichia coli or carcinogenic Helicobacter pylori can alter genome integrity through DNA double strand breaks, leading to chromosomal instability and eventually cancer, our findings highlight possible new routes for further investigations of P. aeruginosa in cancer biology and they identify ATM as a potential target molecule for drug design.
- 2016: I joined the regional Inserm administration office (DR Inserm Rhône-Alpes-Auvergne). My major task will consist in promoting strong interactions and collaborations between Inserm researchers and patients' associations.
I am involved in research dealing with normal or cancerous cell differentiation, with a special emphasis on transcription factors and their interacting proteins, as well as their actions on epigenic modifications and gene regulation. Classical and high performance molecular, cellular and biochemical methods are used to analyze these aspects. The genotoxicity of bacterial pathogens such as P. aeruginosa was investigated more recently. Since the beginning of 2016, I am involved in a NEW PROJECT in collaboration with the national Inserm association office. The goal of this project is to promote strong and fruitfull interactions/collaborations between Inserm researchers and patients' associations.
