Présentation

Mes travaux de recherche s’articulent autour de plusieurs axes :

  • Mécanismes d’adaptation de P. aeruginosa et A. baumannii aux peptides antimicrobiens – Mécanismes de résistance aux antibiotiques des souches cliniques de Pseudomonas spp. et Acinetobacter spp. (épidémiologie, supports génétiques, transferts, caractéristiques phénotypiques)
  • Substrats et régulation des systèmes d’efflux actif de P. aeruginosa (voies de régulation/signalisation, réponse aux stress)
  • Évolution phénotypique et génotypique des souches de P. aeruginosa colonisant l’arbre bronchique des patients atteints de mucoviscidose
  • Mécanismes d’adaptation de P. aeruginosa et A. baumannii aux peptides antimicrobiens
