Biographical Info

Biographical information

After a formation of physicists performed at Orsay University, France, I turned to structural biology and worked at the 3D structure determination of different proteins, like a cattle parasite serine collagenase during my PhD (1989-1993: ICSN, Gif-sur-Yvette, France), or the cellular retinoic acid binding protein (CRBP) during a postdoctoral position in Sweden (1993-1994: Pr A. Jones’ Laboratory in Uppsala). Since the beginning of my carrier at the National Center of Scientific Research (CNRS), France, I also investigate proteins involved in cellular signal transduction (Grb2, Grb14, VEGF, VEGFR, PRL, PRLR).

I took the direction of the group “Antibioresistance, signaling and membrane transport” at the university Paris Descartes in 2009, and since the creation of the University Paris Cité, I am the deputy director of the unit CiTCoM grouping structural biologists with chemists with the common goal to develop therapeutic drugs targeting human diseases considered as major health problem.

I now focus my research on membrane proteins, on transcription regulators from different bacteria, and on all the protein actors of bacterial antibiotic resistance like the tripartite efflux pumps from Pseudomonas aeruginosa.

I am member of several scientific associations: AFC (Association Française de Cristallographie), BSI (Biologie Structural Intégrative), SFBBM (Société Française de Biochimie et biologie Moléculaires), SFB (Société Française de Biophysique), GEM (Groupe d’étude des Membranes), SFM (Société Française de Microbiologie).

Research interests and competencies:

  • Structural biology of membrane proteins
  • Bacterial antibiotic resistance
    • RND transporters, efflux pumps
    • transcription regulators
  • Motion and structural transition in proteins
  • Model of gain-of-function mutants
