Mes activités
:
Mes axes de
recherche sont centrés sur la modélisation, l'analyse et la surveillance des
systèmes vivants. Les trois principaux domaines d'applications sur lesquels je
travaille concernent l'océanographie (et en particulier l'étude des systèmes
planctoniques), le traitement de l'eau par des procédés biologiques et la
production de biocarburants, notamment en utilisant des microalgues.
La première
étape de mon travail consiste à élaborer des méthodes pour déterminer un modèle
à base d'équations différentielles ordinaires. Ce travail s'effectue en
collaboration étroite avec des biologistes et des spécialistes des procédés
biologiques impliqués.
Ensuite il faut
valider le modèle et vérifier qu'il est suffisamment proche du système réel. Je
développe pour cela des techniques pour analyser qualitativement le
comportement du modèle et vérifier qu'il correspond à celui du système
réel.
Une fois qu'un
modèle du système biologique est disponible, je construis des capteurs
logiciels (ou observateurs) qui permettent -en utilisant certaines mesures en
ligned'estimer l'ensemble des variables du système. Sur la base de ces
modèles, je développe également des algorithmes de contrôle pour optimiser le
fonctionnement de bioréacteurs.
Toutes ces
techniques mettent en œuvre les méthodes développées récemment en automatique
non-linéaire et en analyse des systèmes dynamiques, et se conjuguent avec des
protocoles expérimentaux pour valider et améliorer les algorithmes
correspondants.
Mes
spécialités :
La modélisation
des systèmes biologiques, l'analyse de la structure des modèles biologiques, le
lien entre structure et comportement qualitatif, l'analyse de données
expérimentales, la validation des modèles biologiques, les observateurs
non-linéaires, les observateurs par intervalles, le contrôle des bioréacteurs.
Les
(principaux) projets que je coordonne :
TELEMAC IST-2000-28156)
Production de
biocarburants lipidiques par des microalgues (2006-2009). Projet ANR-PNRB, 8
partenaires.
Les
organismes et écosystèmes que j'étudie :
Les bactéries
(boues activées, digestion anaérobie, … ), le phytoplancton (fixation du CO2,
production d’énergie, lagunage…) , les populations zooplanctoniques (étude de
réseaux trophiques), les champignons filamenteux (agroalimentaire), etc.
