Exoplanetology is a young science that genuinely took off in 1995 when a giant planet was discovered in close orbit to the solar star 51 Pegasi. My first researches in this field started in 1999 and were concerned with the space mission Corot that has lead since 2006 to the discovery of more than thirty diverse exoplanets. I have been fully engaged in the Corot adventure, starting with estimating the number of detectable planets from 1999 to 2003, continuing with the search for and characterization of partial eclipse signals, or transits, when the data became available in 2007, and finishing with the measure of orbital and physical properties of detected exoplanets, most notably Corot-7b in 2009, the first rocky exoplanet with measured mass and radius, and Corot-8b in 2010, a dense small-Saturn. Currently, I work on computing the probability of the planetary nature of all transit signals detected by Corot. My other works deal with two high angular resolution techniques for the direct detection of exoplanets: long-baseline infrared interferometry and visible coronagraphy. Interferometry-wise, I compiled two catalogs of calibrator stars suitable for high-precision instrumental calibrations, I measured the properties of a single-mode fiber prototype in the mid-infrared, and I observed dwarf, giant, and double stars. My major result is the detection of the faint companion to Theta Draconis. Finally, coronagraphy-wise, I devised in 2006 a speckle-nulling approach by way of a deformable mirror, to be used in the framework of Nasa's Terrestrial Planet Finder Coronagraph project. In case Esa selects the Echo project in February 2014, my future works might be dealing with the transmission spectrometry of short-period exoplanet atmospheres.
