Since 2004, I have been involved in several projects dedicated to the direct imaging and the spectro-polarimetric characterization of exoplanets at wide separations (1 to 500AU), mainly Jupiter-, Neptune- and super-Earth-like planets around young nearby stars.
In 2004, I worked at the Subaru telescope on a high contrast imaging apodizer (PASP paper) in the context of the Terrestrial Planet Finder (TPFC, NASA). The instrument I studied is now used or foreseen in most of the North American instruments for exoplanet imaging.
Then, I spent four years (2006-2010) at the Paris Observatory (France) doing research and development in high contrast imaging using both laboratory experiments and numerical studies for both space missions (SPICES, ESA Cosmic Vision) and ELT (CRAS, A&A, and A&A on the Self-coherent camera that calibrates and reduces the speckle noise and A&A on an ELT achromatic coronagraph that attenuates the stellar light to look for faint objects in its neighborhood).
Between 2010 and 2012, I was working as a postdoc at the Herzberg Institute of Astrophysics in Victoria (British Colombia, Canada). I reduced all the images taken at Keck, Gemini North, Gemini South, VLT, HST for the International Deep Planet Survey by direct imaging from 2001 to 2011. I was also working on statistics to determine the giant planet frequency around nearby MFGKA stars. Moreover, I found several objects that could be Jupiter-like planets and I regularly observe them to confirm they are not background objects (some are very promising). I also developed a new background subtraction technique to obtain the first image of exoplanets at M-band (ApJ). I was involved in the development of the official pipeline for the Gemini Planet finder Instrument (GPI).
Since 2012, I work at the Paris Observatory and at the University of Paris Diderot as an associate professor. Mainly, I develop new instruments for high contrast imaging (numerical simulations and laboratory) like the SAXO+ system for the SPHERE+ upgrade of the SPHERE/VLT. I regularly use the current instruments like SPHERE/VLT.
Since 2019, I am also the co-leading the biomedical application team. We develop a confocal plus lightsheet microscope using adaptive optics for imaging rodent brains. We collaborate with the Institut de Biologie de l'École Normale Supérieure (IBENS).
