Les recherches que je conduit/dirige ont comme cadre conceptuel la biologie évolutive. L'objectif principal est de comprendre les déterminants génétiques et écologiques du fonctionnement des populations dans l'agro-écosystème. Nous étudions plusieurs acariens Tetranychidae présentant des adaptations à la plante ou qui sont des espèces envahissantes. Ces acariens sont souvent des bioagresseurs, ce qui nous amène à nous intéresser à des méthodes de contrôle innovantes et durables en protection des cultures. Les évolutions environnementales liées aux changements globaux ont des répercussions sur la répartition des espèces et les risques sanitaires qui sont associés, sont des questions que nous explorons aussi sur le modèle acariens. Une approche qui est renforcée à la faveur du financement FACCE-ERA-NET+ :

Depuis 2009, je suis membre du Plant Health Panel de l’European Food Safety Authority (EFSA) basée à Parma (Italie) et j’ai été nommée vice-chair du panel (2015-2018) ou j’ai une activité d’analyse de risque en santé des plantes au niveau européen.
