Position and Education

  • CNRS research engineer, GQE-Le Moulon (Gif-sur-Yvette, France), 2004-present
  • CNRS engineer, EGCE (Gif-sur-Yvette, France), 1996-2003
  • Bioinformatics post graduate degree (Université Pierre et Marie Curie, Paris VI), 1995

Research interests

I am interested in computational challenges raised by highthroughtput proteomics studies (data storage and intensive calculation). In charge of the bioinformatics developments of the PAPPSO team, I thus lead several projects :

We have developped a complete solution using free softwares and common hardware to store 30Tbytes per year and offering high speed connection to an HPC cluster (based on ceph and HTCondor).

I am also involved in the GQE Bioinformatics facility ( ABI   ), in which I lead the ABI-SYS   group (system).
