In 2007 he was appointed professor at the Faculty of Science at the University of Geneva.
job
At the beginning of his career, Udry studied the dynamics of galaxies . His main field of work today, however, is the measurement of radial velocities of other stars in order to find extrasolar planets. So far, Stéphane Udry has been involved in the discovery of over 100 exoplanets. Among them is the planet Gliese 581 c , the first earth-like planet discovered to date on which liquid water could possibly exist.
