Lépine is professor at the Instituto de Astronomia, Geofísica e Ciências Atmosféricas, University of São Paulo. He obtained his PhD in 1977 at Université de Paris VII, and became full professor at the University of São Paulo in 1999. He made important contributions to Astronomy, like the discovery of the first water vapor extragalactic megamaser, and the study of a Cassini-like ring in the Galactic disk with a minimum of stellar density and also of gas density, at the corotation radius. Lepine was the Director of his Institute from 2001 to 2005, and President of the Brazilian Astronomical Society for 2 years in the past. He is now the coordinator on Brazilian side of the joint Brazilian-Argentinean LLAMA project, which is installing a 12 m radiotelescope for sub-mm waves in the Andes, at 4800 m altitude.
