French National Institute for Agricultural Research




          INRA was set up in 1946 in response to pressing demands from society to “feed France.” Today challenges such as climate change, the nutritional status of populations, the ecological equilibrium of rural areas and the competitiveness and sustainability of production are global in nature, and agriculture plays a key role in overcoming them. INRA’s research is at the heart of these issues. The French National Institute for Agricultural Research (INRA) produces scientific knowledge and works for economic and social innovation in the areas of food, agriculture and the environment. There are 18 Research Centers (mainly in France and overseas departments), more than 200 Research Units and 50 experimental & technical platforms. With 74% of staff based in the provinces on more than 150 sites, the Institute is present in almost all French regions, including those overseas.The missions:

  • Produce scientific knowledge

  • Develop innovations and know-how

  • Inform public decision-making

  • Develop scientific culture and participate in the science/society debate

  • Contribute to training in and through research

  • Promoting ethics and a code of conduct



The Research Unit UR454 belongs to the Microbiology and Food Chain Department (MICA) and is localized in Saint-Genès-Champanelle, France. The Research Unity’s project aims to characterize the adaptation of bacteria, including enterhemorrhagic Escherichia coli (EHEC), to digestive and food environments and the interactions of intestinal microbiota with humans. UR454 goals are related to human health through food safety, prevention of infectious diseases at EHEC and functional pathologies. The area of expertise is the digestive and food microbial ecosystems and their interrelations with the host, animal or human (impact on nutrition and health) or environment (quality of food).

Applied Mathematics and Computer Science, form Genomes to the Environment (MaIAGE) is a research laboratory in Jouy-en-Josas, France. The MaIAGE laboratory gathers mathematicians, computer scientists, bioinformaticians and biologist to tackle problems coming from biology, agronomy and ecology. MaIAGE develops original methods in mathematics, statistics and computer science which are generic or driven by specific biological problems. A particular attention is paid to develop and make available softwares, databases, ontologies and web services so that biologists can use them easily to analyze their data or to mine the scientific literature.

Research Interests

The main scientific interests of V. Fromion are in the fundamental research on Systems and control Theory: linear and nonlinear control. He has a great interest to the so-called robust control approach and he made contributions in the extension of the H-infinity control approach to the nonlinear context. He also had an interest in a related question about the theoretical foundation of the gain scheduling approach and about subjects on the LPV analysis and control in collaboration with Pr. Gérard Scorletti. He has also strong interest for various kinds of applications. His first interest was about the control of highly-maneuverable missiles. More recently, He investigated modeling and control problem attached to open channel hydraulic systems in collaboration with Dr. X. Litrico. Since 2005, he joined the MaIAGE laboratory in order to head a project on Systems Biology about the understanding of regulatory networks of biological system. He has been involved in the EU BaSysBio project (2006-2010) and BaSynthec project (2010-2013) where He led the System Biology/Synthetic workpackage. He also coordinates the French project « Institute for Modelling Living Systems » (IMSV, 2013-2016) involving 11 research institutions and 6 Labex of the University of Paris-Saclay, France.

Research Interests

My research focuses mainly on statistical bioinformatics with applications to bacterial genome analysis (genome analysis, transcriptomics, population genetics). In particular, I have a strong interest for the analysis of sophisticated statistical models involving unobserved latent variables that can serve to represent complex dependences such as arising in phylogenetically, spatially, or temporally related data.
