He worked at CERN (European Organization for Nuclear Research) since 1989 and moved to the USA in 1990 where he became Professor of Physics at Stanford University.

 Among the various awards he's received for his work on inflation, in 2002 he was awarded the Dirac Medal, along with Alan Guth of MIT and Paul Steinhardt of Princeton University. In 2004 he received, along with Alan Guth, the Gruber Cosmology Prize for the development of inflationary cosmology.
