**Equipe SeeDev, UMR 1318 Institut Jean Pierre Bourgin, INRA, centre de Versailles** From my past and present research achievements, I have acquired a good expertise in plant molecular genetics. My technical skills are based on the tools of molecular biology, cytology and bioinformatics and serve to answer biological questions involving seed development. My main topic is the transcriptional network controlling the switch between embryogenesis and accumulation of reserves. I am focusing on LEC2, a master regulator of seed maturation belonging to the B3 family. My work aims to determine (i) how this factor binds, or interact, with its DNA targets, in a possible complex with ABI3 and FUS3, (ii) how is this protein complex is regulated, and (iii) how LEC2 is transcriptionnaly and post-transcriptionally tuned. We aim at modelling the regulatory network involved in Arabidopsis and investigate how it is conserved in cereals. Scientific manager of the cytology and imaging platform of the Plant Observatory, I ensure the proper scientific and human functioning of a strategic tool for my institute (1200M2, 5 Full Time Equivalents, 100 regular users, 5 confocal micoscopes, laser microdissector, twenty large optic pieces, and various cytology-related materials http://www.versailles-grignon.inra.fr/pciv). Operating correspondent for the institute, I manage all aspects of the unit's 9 buildings (8000M2), requests for equipment, works, modifications, in relations with the research center for all these aspects. I am also managing the unit’s workshop (3 FTEs).
