Current position

I am the head of the Bioinformatics & Informatics service of IRCAN (“Institute for Research on Cancer and Aging of Nice”). The main part of the service activity is to interpret and analyze the data coming from IRCAN's teams experiments such as NGS data generated by our high throughput sequencers. More generally, I perform in silico biology to find hidden relevant biological information in the flow of binary digits !

Responsible of the “Bioinformatics and Informatics” service at the IRCAN institute -
Institute for Research on Cancer and Aging of Nice, Nice, Faculty of Medicine, CNRS UMR 7284. I mainly explore and examine biological data from several disparate sources. See my current works for more !

Bioinformatics plateform of the IHU (Institut hospitalo-universitaire) at Marseille, located at medical school, La Timone (previously the Rickettsia unit, URMITE - UMR 7278). The institute is headed by Pr. Didier Raoult.
I was in charge of the analysis of the data produced from our NGS platform. The platform currently comprises many pyrosequencing machines: 3 Roche 454 (GS20, XL+ and a Titanium), 1 ABI SOLiD, 1 IonTorrent PGM, 2 MiSeq Illumina).
My interests are also to look inside the genomes of prokaryotes and virus using in silico existing or homemade tools for discovering meaningful cryptic information.

PhD summary:

PhD summary:

Identification of organisms are still often based on phenotypical characters. However, such as an identification is approximate and difficult for micro-organisms. DNA micro-arrays appear to be a solution for a fast and reliable identification of a large number of species. This technique is relatively recent and it is still necessary to improve it, in particular at the conceptual level. Within this framework, the objective of my thesis was to implement new means for chip design. This work was completed through two projects: The project “Aquachip” aimed in designing a DNA array for the identification of pathogenic bacteria present in bathing and drinking water. The project grouped several European laboratories that had to exchange a large amount of data. Such significant flow of information is often badly managed and slows down research. Consequently, we developed a dynamic numerical platform, the “E-dashboard” (MySQL, PHP), allowing all partners to manage data. This tool made it possible on the one hand to follow the progress of the various steps of the project and on the other hand to optimize exchanges between partners. In a second project, “Mycochip”, the objective was to develop a DNA array to identify ectomychorizian fungi. ITS sequences (Internal Transcribed Spacers) from a very divergent area located between ribosomal RNA genes are used for this study. The project initially required the development of a tool to retrieve sequences, « EmblEx » (Perl, MySQL), which is more specific and powerful than Entrez, SRS or ACNUC. Then, the ambiguous taxonomy of fungi led us to conceive a new method of classification through partitioning without alignment. Biological experiments showed that reliable probes could be determined by this approach.
