After an engineer diploma in hydraulics and fluid mechanics (at ENSEEIHT, Toulouse, France), I started a Phd thesis in environmental sciences in a laboratory (CEREVE) belonging to the water and forest engineering school (ENGREF) and to the bridges and roads engineering school (ENPC) in Paris. I got a position then in administrative research for IFREMER (French National Institute for Marine Research) in Brussels. Then I got a job at Numeca Int SA, Brussels, working on environmental applications of a CFD software. I also worked for INRIA (French National Institute for Research in Computer Science and Control) on fluid-structure coupling before I became assistant professor in Fluid mechanics at the French National Agronomic Institute (INA-PG) in Paris in 2001. Finally, I got an assistant professor position in Agrocampus Ouest, Angers, France in 2001. In 2011, I became professor in physics of transfers and since 2012, I am the head of the EPHor (Environmental Physics and Horticulture) research unit.

I belong to the Environmental Physics and Horticulture research unit (EPHor), AGROCAMPUS OUEST.
My research interest is about the coupled mass-energy transfers in the context of horticultural production. I mainly focus on the modelling of greenhouse distributed climate with a particular attention paid to the radiative transfers and interactions of the crop with the local climate. Recently, we paid attention to the impact of water restriction on the energy and water transfers in the substrate-plant-atmosphere continuum.
The models developed for the horticultural applications are currently adapted to urban applications. The aim there is to reduce water consumption while guaranteed the ecosystem services of the urban plants – particularly the evaporative cooling to mitigate the urban heat island effect.
I also developed activities on livestock buildings. The aim was to characterize the climate inside such buildings in terms of temperature and humidity, but also to analyze gaseous transfers (ammonia in particular) and plume spreading outside of the building.
Former and current fields of research:
• environment (hydrodynamics, pollutant transfer, atmospheric flows …),
• limnology, river and marine hydraulics, naval hydraulics,
• thermics, cooling processes (for food conservation),
• fluid-structure interaction (applied to bridges),
• greenhouse climate (opening management, energy balance, plant-climate interaction, impact of water restriction, condensation),
• livestock building climatics (climate distribution, gaseous transfers).
These two las topics correspond to my current research activities.
Keywords: greenhouse, livestock building, fluid mechanics, thermics, radiation, coupling, turbulence, CFD, numerical methods, sensible and latent heat, porous medium, metrology
Recently finished programs
• Plantinov’ser (2009-13): Funded by ADEME and Région Pays de la Loire. This project aimed at limiting the greenhouse crop systems energy consumption by providing new cultivars and new climatic strategies. The research unit showed the economic and technical interest of dehumidification heat pump. Experimental validation conducted on ornamental crops evidenced the efficiency of our innovative control strategy.
• Physi’Ho (2012-16): Funded by Région Pays de la Loire and growers. The project aims at understanding the interactions between climate, pathogens and hydrangea physiology, and their influence on the plants storage.
• Conser (2012-16): Funded by Région Pays de la Loire and growers. This project aims at improving the understanding of the cucumber plants responses to greenhouse climate. The project made a physiologic reference of the cucumber photosynthetic efficiency according to climatic conditions in order to improve the energetic efficiency of the climate strategies.
• VégétEauVille (2016-19): funded by ADEME. A Ph. D position stared in October 2016 to quantify the water and energy transfers in the soil-plant-atmosphere continuum in urban condition. The project aims at determining the plant’s influence on the urban microclimate when under water restriction.
• Projet OBAUC (2016-17): funded by Région Pays de la Loire. The aim of the project is to characterize plant-environment interrelations, to understand and predict plant development. The specific goals are to analyze the combined effects of soil compaction, water supply restriction and shading on plant transpiration, plant biomass as well as aerial and root architecture.
• Nature 4 Cities (2016-20): Funded by the European Commission (H2020). Nature4Cities aims at developing complementary and interactive modules to engage urban stakeholders in a collective-learning process about renaturing cities, develop and circulate an extensive knowledge base on Natural Based Solution (NBS), new business, financial and governance models for NBS projects, as well as providing tools for the impact assessment, valorization and follow-up of NBS projects. Our aims will be to provide performance assessment of NBS regarding a range of urban challenges by providing definitions of a multi-scalar and cross-thematic sets of urban performance indicators.
