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).
