Nicolas Crouzet

Research Fellow


Main Research Fields

My scientific interests are related to the search and characterisation of extrasolar planets. I detect exoplanets through their transits, and I study their atmospheres. I am also involved in astronomy from Antarctica.

Exoplanet atmospheres: I observe exoplanets by spectroscopy to derive their atmospheric composition, structure, temperatures, winds, and cloud coverage. I use HST and ground-based telescopes, and I prepare future observations with JWST.

Exoplanet detection: I develop and use wide-field photometric instruments to detect exoplanets by the transit method.

Astronomy from Antarctica: I develop instruments that perform photometry during the continuous night of the Antarctic winter.
