Research

Current Research Topics

My research lies in the field of agronomy and aims firstly at analysing the diversity of crop management, including rotations in conventional and organic farm in order to assess their impact on biodiversity at the local scale and the landscape scale.
Secondly I conduct research with agricultural extension services in order to develop tools and methods to help farmers move to more agro-ecological crop management practices. In particular, I focus on agricultural work change in these tools and methods.

Current Projects 

• SEBIOPAG-PHYTO: Stimulating natural pest regulation through the diversification of cropping systems at the landscape scale. FRB (The Foundation for Research on Biodiversity) project

Participation in Networks

• Member of the SEBIOPAG network on biological control.
• Member of the group of agronomist of the INRA SAD department.
