Sébastien Gérard is a CEA LIST senior researcher in software engineering and computer science. He graduated in 1995 from ENSMA (the Superior School of Mechanics and Aeronautics in Poitiers, France) as a mechanical and aeronautics engineer, after which he obtained a doctorate in computer science from the Evry university in France in 2000 . He is currently leading a research team of about 20 people at CEA LIST (an arm of the French Atomic Energy Agency, http://www-list.cea.fr/gb/index_gb.htm) within the LISE (Laboratory for Model-based Engineering of real-time and embedded (RT/E) systems). The principal objective of this research of this team is to achieve “correct-by-construction” design of RT/E systems from requirements to implementation”. Through his involvement in a numerous national and international research projects, Dr. Sébastien Gérard has worked with many industrial partners such as Peugeot Citroen, Airbus, ST Microelectronics, EADS, gaining extensive experience and insight into industrial problems and requirements. Dr. Sébastien Gérard is also deeply involved in various standardization activities, and is currently co-chairing the MARTE (the UML extension for RT/E) revision task force. He is also core member of the European network of excellence, ArtistDesign (http://www.artist-embedded.org), and the prime leader of th action support for MARTE, an IST project called ADAMS. In addition, Dr. Sébastien Gérard is a member of the editorial board of the SoSyM journal, co-founder of the summer school on model-based development for DRES (http://www.mdd4dres.info) and a frequent member of program committees of major technical and scientific conferences (MODELS, ECRTS, ISORC, etc.). Finally, he is the leader of the Eclipse project Papyrus (www.eclipse.org/papyrus). This latter is an open-source implementation based on the Eclipse framework providing a graphical modelling support for the UML.
