BIOGRAPHIE :

Mes activités de recherche s’articulent selon trois points :

1-Etude du comportement et de la survie des bactéries soumises à des conditions environnementales adverses. Mise au point et développements méthodologiques, notamment les bactéries témoins de contamination fécale (BTCF), dans les sédiments du bassin versant de la lagune de Thau (programme chantier lagune EC2CO), dans les sédiments du grand récif de Tuléar à Madagascar (programme ICART, EC2CO), dans la lagune de Bizerte en Tunisie (convention de collaboration CNRS n° 013381 avec l’INSTM de Tunis), Estuaire du Sénégal (programme PNEC DELSEN).

2-Rôle des microorganismes dans les écosystèmes aquatiques, développement de protocoles de quantification (bactéries, cyano-bactéries, pico-nano phytoplancton) par cytométrie en flux, (mesures de biomasses,Taux de croissance), Lagune de Thau ( Programme EC2CO Forçages environnementaux sur le réseau trophique), Estuaire de Bach Dang, Vietnam (Programme EC2CO Haïphong), Grand récif de Tuléar (programme ICART, EC2CO), Iles Eparses (Programme CNRS-INEE-TAAF), Lac cratére du Dziani Mayotte (ANR Dziani et Fondation Total Dzaha). Cet aspect faisant aussi l’objet de formation d’étudiants (M1, M2, Doctorants, Post-Doc) intra-muraux et de collègues étrangers (Tunisie, Sénégal, Vietnam).

3-Etude du stress chez certaines populations bactériennes par la mesure de leur état physiologique par cytométrie en flux (ADN, membrane, respiration), chez une bactérie symbiotique d’une palourde (codakia orbicularis), sur des souches de vibrio splendidus soumises à l’effet de peptides antimicrobien de l’huitres (crassostreas gigas ), sur des communautés naturelles en présence de pesticides (programme CNRS-INEE Juan de Nova), en présence de contaminants issus des sédiments (ANR RISCO).

MARBEC MARine Biodiversity, Exploitation and Conservation, est une unité de recherche qui regroupe des personnels de 4 organismes : l’IRD, l’Ifremer, l’UM et le CNRS. Son objectif est l’étude de la biodiversité marine des écosystèmes lagunaires, côtiers et hauturiers à différents niveaux d’intégration, depuis les aspects moléculaires, individuels, populationnels et communautaires, et des usages de cette biodiversité par l’Homme.
