I used and still use instruments on different telescopes in order to detect or characterize faint sub-stellar objects around nearby stars.

After working for the North American Gemini Planet Imager (GPI) project, I joined the European SPHERE team. Both GPI and SPHERE were built as survey instruments to detect planets and image debris disks. GPI, SPHERE, and their Japanese counterpart HiCIAO/SCExAO will produce the first-ever robust census of giant planet populations in the 5-50 AU range, allowing us to 1) illuminate the formation pathways of Jovian planets; 2) reconstruct the early dynamical evolution of systems, including migration mechanisms and the interaction with disks and belts of debris; and 3) bridge the gap between Jupiter and the brown dwarfs with the first examples of cool low-gravity planetary atmospheres.
During the IDPS, I derived the following solution to correct the field distortions in NIRI images.
