THÉMATIQUES DE RECHERCHE


Mes travaux combinant les outils de biologie moléculaire et de physiologie portent sur l’interaction des plantes avec leur environnement. Comprendre ces relations plantes-environnement, c’est apprendre à mieux utiliser les végétaux pour faire face aux grands défis environnementaux du XXIe siècle. Développer une agriculture résiliente qui saura faire face aux changements climatiques, réduire la production de gaz à effet de serre, dépolluer les sols, l’eau, l’air, tels sont les services qui peuvent être rendus par les plantes.

En tant que phytotechnologiste, mon objectif est d’affiner notre compréhension des mécanismes naturels permettant l’établissement des végétaux dans ces contextes stressants. L’intention est de pouvoir proposer des solutions plus fiables et plus efficaces et donc de faciliter le développement des phytotechnologies à plus grande échelle.

Mots-clés: Aquaporines • Lutte biologique • Physiologie moléculaire des végétaux • Phytotechnologies • Relations plante-eau
