Research interests

During 8 years in 2 German laboratories (at BASF and the University of Constance), my research focused on the biochemical mode of action of chloroacetamide and other herbicides in plants. At the University of Reims, my research has mainly focused on pesticide ecotoxicology, biomarker development, phytoremediation and also fate of pesticides in the environment. I mainly use aquatic plants and algae as models for my research and occasionally invertebrates. I have also been involved in research about grapevine bio-protection against Botrytis cinerea. Research key words: pesticides, pollution, ecotoxicology, plant physiology

Technical skills

Plant cell culture, analysis, chromatography, enzyme activity

Ecology, environment, crop protection, environmental risk, GENI

Research program coordination

Coordinator of AQUAL research program (2007-2014) “Control of non-point source pollution in rural area”
