Henri Boffin is a Paranal Operations Staff Astronomer since August 2010. He obtained his PhD from the Université Libre de Bruxelles, Belgium, in 1993, working on explaining chemically peculiar red giants, in particular Barium stars. Since then, his research is devoted to the world of close binary stars, their formation and evolution. To this aim, he combines both observational and theoretical work, including hydrodynamical simulations. He spent 2 years as a post-doc in Kobe, Japan, working on cataclysmic variables, and another 2 years in Cardiff, Wales, UK, in the Star Formation group. In 1998, he came back to Brussels, obtaining a permanent position as Senior Researcher at the Royal Observatory of Belgium. There, he organised the first international workshop on Astro-tomography. As he is very keen to share science with society, he also graduated from the 1st promotion of “Journalist & Scientist” at the Ecole Supérieure de Journalisme de Lille, France. He has had experience in journalism and editing, and in 2003, joined ESO as Astronomer and Press Officer, dealing with communication about all telescopes and projects of ESO. He was member of the steering committee of the very successful Venus Transit 2004 Programme and of the EIRO forum Science on Stage festivals, and coordinator of the IYA 2009 Gigagalaxy Zoom project. His current scientific interests also include Am stars and binary nuclei of planetary nebulae, but more generally all interacting binary stars.
