1993 - PhD thesis in Agronomical Sciences, speciality Plant Science.
2009 - HDR, Accreditation to supervise research, Avignon University.


Since 2001, I am researcher in the team « ecophysiology of fruit quality » in the unit PSH (Plantes et Système de culture Horticoles) of INRA Avignon. My research focuses on the regulation of fruit growth and quality (size, composition and texture) in tomato. I investigate the involvement of main processes in the genetic and environmental variations of fruit quality: cell division, cell expansion, DNA endoreduplication, water and carbon fluxes at the fruit and tissue level. More recently, I develop some work to analyze the role of the fruit compartmentation into differentiated tissues on its growth and textural traits. Knowledge is integrated into simulation models which can be used to analyze interactions among processes during fruit development, as well as genotype x environment interactions. The links between genes or proteins and tissue or fruit state variables, are studied in collaboration with geneticists and statisticians to outline functional links between the different scales of controls (from gene to organ).
I am involved in one European project and several national projects.

* EU-SOL (European project PF5 Food Safety and quality 2006-2011): High Quality Solanaceous Crops for Consumers, Processors and Producers by Exploration of Natural Biodiversity.
* FRIM (European Project ERASysBio+ 2010-2013): Fruit Integrative modelling
* 3D virtual fruit (Agropolis project 2009-2012): 3D virtual fruit - application to the control of fruit growth and quality.
* QualiTomFil (PNRA-ANR 2007-2009) : « Construction et valorisation de la qualité organoleptique et nutritionnelle de la tomate tout au long de la filière ».
