Research

Current Research Topics

I develop researches in the field of landscape agroecology, in order to assess the effects of cropping systems (organic and conventional systems) and semi-natural habitats (hedgerows and grassy field margins) on insect communities involved in ecosystem services of pest biocontrol (carabid beetles, ladybirds), pollination (bees) and biodiversity conservation (butterflies). My aim is to explore diverse management options at different spatial scales to encourage biodiversity and associated services:
• changes in cropping systems at the field scale,
• hedgerow plantation and management at the field margin,
• landscape design through greenveining or land-use diversification at larger spatial scales.

Current Projects

• CONYCIT: Linking landscape, biodiversity and sustainability in agroecosystems. International cooperation with Catholic University of Santiago (Chili)
• AG-FORWARD: Agroforestry for rural development. EU project.
• SOLUTION: Stimulating natural pest regulation through the diversification of cropping systems at the landscape scale. FRB (The Foundation for Research on Biodiversity) project.
• SEBIOPAG-PHYTO: Survey of the ecosystem services fulfilled by biodiversity in agricultural landscapes. FRB project.

Participation in Networks

• Member of the SEBIOPAG network on biological control
• Member of the group of ecologists of the INRA SAD department
• Member of the landscape ecology thematic group of the French Ecological Society (SFE)
