Research interests and expertise

I am a biologist especially interested in the functioning of ecological interaction networks.  While I studied the emergence of network structure and the consequences for pathogen transmission, my recent research focuses on trophic network involving arthropods associated with crop plants as pests or natural enemies of pests. I am particularly into NGS of agricultural communities and variation in network structure.

Current and recent activities

ARENA – “Anticiper les REgulations NAturelles”
Casdar fundings- 2017-2020
ARENA aims to assess the role of beneficial insects – natural ennemies – in controlling pests in crops. ARENAWebsite

MIRAAC -“Microbiotes Intestinaux et Régime Alimentaire des Auxiliaires Carabiques”
SPE fundings – 2017-2018
The goal of MIRAAC is to assess the reciprocal effect of gut microbiotes and diet for beneficial and opportunistic carabid populations in crops.

NGB -“Next Generation Biomonitoring of change in ecosystem structure and function”
ANR fundings – 2017-2020
The goal of NGB is to develop and test a generic next generation biomonitoring approach that will improve the detection of ecosystem-wide change, using a combination of Next-Generation Sequenced DNA data and Machine Learning. NGBWebsite
