Last Update: June 2011	Welcome to my web page! Previous Previous Location: Cerro Tololo Interamerican Observatory, Chile. Previous Location: Dept. of Astronomy, U. de Concepcion, Chile Current Location:  CEA Saclay, France Next Location: Who knows!     Currently  (since June 2010) I'm with Dr. David Elbaz in the Laboratory of Cosmology and Galaxy Evolution of the Service d'Astrophysique at CEA Saclay, France. We are studying the evolution of galaxies and the star-formation history in the GOODS fields using the state-of-the-art data from the Herschel Space Observatory in the context of the GOODS-Herschel consortium.      In 2005 I started to work in the Department Astronomy of the Universidad de Concepcion (UdeC), Chile, as research assistant for Dr. Doug Geisler in the  NASA's Space Interferometry Mission (SIM) Key Project:"Taking the Measure of the Milky Way" and also was in charge of the in-campus observatory.  In 2007 I begun my Ph.D. studies of Physical Sciences under the supervision of Dr. Neil Nagar investigating radio jets in Seyfert galaxies and ultraluminous infrared galaxies.    Before 2005 I worked in the Cerro Tololo Interamerican Observatory (CTIO) with Dr. Chris Smith in the Magellanic Cloud Emission-line Survey (MCELS), a joint project between CTIO and University of Michigan. I was interested in finding and studying supernova remnants in the Magellanic Clouds using the MCELS dataset.  I also worked with other CTIO staff members in different short projects (Dr. A. Tokovinin on "Incrementing the 9th Catalog of Radial Velocities for Spectrophotometric Binary Systems"; Dr. Patrice Bouchet doing infrared Photometry of SNe, and, with Dr. Mark Phillips "Measuring the Sky Brightness in CTIO" ) and observations for different projects (MCELS, ESSENCE, High-z SN Search, MACHO, SUPERMACHO, 2-Micron All Sky Survey). At the same time, I worked as observing and telescope support for CTIO visiting astronomers.    Since 2002 to 2010, I represented the International Dark-Sky Association (IDA) in Chile. The mission of the IDA is to preserve and protect the nighttime environment and our heritage of dark skies through quality outdoor lighting. I've also been involved in observations and collaborations in other topics like supernovae, variable stars, minor planets and comets. Other interests: science in general (physics, biology), history of science, science and society; science fiction; environment; photography;  history in general. GOODS-Herschel UdeC's Astronomy Dept.
