After his military service at this observatory he was hired as a “Fellow”. In 1979 he obtained a university degree for “Upper Studies Thesis in Astronomy” ("ThĂšse de 3eme. Cycle") at Paris VI University under the directorship of Professor Pierre LĂ©na. He was then appointed as a Staff Astronomer at La Silla Observatory, as head of the Night Assistants group and Operations group. In 1986 he led the infra-red section at La Silla Observatory. Doctor in Science in 1990, (Ph.D.) in “Astrophysics and Spatial Techniques” with the thesis "Les 1001 nuits de SN 1987A: contribution aux observations dans l’infrarouge entre 1 et 20 ”m", at Paris VII University (Thesis director: Prof. 125:
Falomo and collaborators); a monitoring in the near-IR range of a sample of Wolf-Rayet stars which shows that condensation of dust in their wind occurs in a short time scale (∌1–2 years), and that the newly formed dust shells are dissipated on time scales of about 4 years (with Prof. K.A. van der Hucht and collaborators); observations of the mutual eclipses and occultations between the Galilean satellites to derive the corrections of the ephemerides during the events and to get the measurements of the position of hotspots on Io’s visible surface. Together with his observations, a model including the thermal emission of the volcanoes has permitted a close representation of the IR lightcurve and has provided new physical parameters related to the two volcanoes Loki and Pele (with Dr. J.E. Arlot and collaborators).

He was also member of the National Chilean Telescope Time Allocation Committee which evaluates observing proposals for CTIO and Las Campanas Observatories, and a frequent reviewer of the governmental FONDECYT (“FONdo de DEsarollo en Ciencia Y Tecnologia”) and CONECYT (“CONsejo para la Educacion y Tecnologia”) proposals for research funding. He collaborated on a regular basis to the REDLASER organization, which gather teachers from the IV region of Chile for divulging astronomy in colleges, as well as with various amateurs associations in France and Europe.

They concluded that whether all stars arrive on the main sequence surrounded by a disk cannot be established: they showed, in particular that not only some very young stars do not have a disk, but also not all stars destroy their disk in a similar way: some stars as old as the Sun still have significant disks. 103:
characteristic of FU Orionis star and indicative of a hot luminous disk, and they suggested that BBW 76 is virtually identical to the prototype of its class, FU Orionis itself, in all respects except that BBW 76 has not shown the regular fading that FU Orionis has displayed after its eruption in 1936. This may be due to continued replenishment of the circumstellar accretion disk.

In collaboration with Dr. Bo Reipurth, he has carried out a long-term photometric and spectroscopic monitoring program of the southern FU Orionis-type object BBW76 spanning the period from 1982 to 1997.
