She earned her PhD degree in Plant Sciences in 1990 from the South Paris University where she studied in vitro plant regeneration in rice. Then, she undertook a post-doctoral year in breeding rice for resistance to blast at the International Rice Research institute in the Philippines. When she joined INRA in 1992, she switched to working on vegetable crops, specializing in resistance to insects. For several years she worked overseas in La Reunion Island in the Indian Ocean and Guadeloupe Island in the French West Indies, both islands that offer an excellent ‘playing field’ to investigate efficiency of plant resistance in different agro-ecological environments. At that time she specialized in resistance to Hemipterans and their transmitted viruses. When she joined GAFL, she became part of the team working on plant resistance durability and focused on the trio Melon/Aphis gossypii/viruses, taking advantage of fruitful research initiated by Michel Pitrat and Hervé Lecoq. She aims to understand plant resistance, from genetic architecture to effects in the field, bringing together entomologists, virologists, geneticists and modelling to investigate key determinants of plant resistance durability.
