1984 PhD thesis in Agronomical Sciences, speciality Ecology.
1999 HDR, Accreditation to supervise research in life sciences, Montpellier II University.
Head of the unit Plants and cropping Systems in Horticulture (UR PSH). The unit, composed of 25 scientists (more than 50 permanents) is involved in research on horticultural food productions, mainly fresh fruits and vegetables. It aims at predicting the effects of cultural techniques on the quality of products and promoting environment-friendly practices.
Coordination of the Pole for Integrated Horticulture (PHI) of the INRA Avignon Center


Description and understanding of the components of fleshy fruit quality, considering genetic and plant controls, in relation to the environment and cultural practices. Research is conducted from the viewpoint of a quantitative integration of physiological functions in models explaining fruit development and quality. With this approach, scientific innovation emerges as much from the integrative viewpoint as from process descriptions. Many models describing the main physiological processes involved in cell division, DNA endoreduplication, fruit growth, sugar and acid accumulation and ethylene metabolism have been developed. These models have been integrated in a Virtual Fruit model that can be used to analyse phenotypes following a virtual profiling approach.
