I work as a researcher at INRAE (formerly INRA) on the Jouy-en-Josas campus in MaIAGE laboratory ("Mathématiques et Informatique Appliquées du Génome à l'Environnement"). My research focuses mainly on statistical bioinformatics with applications to bacterial genome analysis (genome analysis, transcriptomics, population genetics).

Doing what

  • BioBrickEvolver an ongoing collaborative research project.
  • SHOW, a powerful self-training bacterial gene detection program (among other things) that I developped during my PhD.
  • TREEMM, a program that I developped for de novo identification of Sigma factor binding sites based on promoter sequence and expression data.
  • Multiple, a program to search for transcription factor binding sites with the help of expression data (condition-dependent profiles and position of transcription start sites)
  • A laser-cut peristaltic pump that we designed to operate miniature bioreactors such as used in experimental evolution.
  • Mémoire d'Habilitation à Diriger des Recherche (HDR, in French)
  • Data browsers for large transcriptomics data sets on Bacillus subtilis and Staphylococcus aureus.
