List of adapted databases available at: http://cvn.fecyt.es/ efb743b564d783564de108b1a8c5de25 Summary of CV This section describes briefly a summary of your career in science, academic and research; the main scientific and technological achievements and goals in your line of research in the medium -and long- term. It also includes other important aspects or peculiarities. Basic research in Astronomy and Astrophysics on the following topics: a) Formation and evolution of planetary nebulae. b) Interaction of evolved star stellar winds with circumstellar medium. c) Multi-wavelength study of interstellar bubbles. I got my PhD in 1995 on the spatially-resolved study of the chemical abundances of planetary nebulae (Univ. La Laguna, Instituto de Astrofísica de Canarias IAC, Tenerife, Spain). Then I was hired by the IAC as a member of the Support Astronomer group at Observatorio de El Roque de los Muchachos (ORM, La Palma, Spain). In 1999 I moved to the University of Illinois at Urbana-Champaign (USA) where I stayed until 2003, when I moved to the Instituto de Astrofísica de Andalucía (IAA) of the Spanish Consejo Superior de Investigaciones Científicas (CSIC) with a Ramón y Cajal tenure-track position. This tenure-track position moved into a permanent position (Científico Titular) in July 2006, being promoted into the next level (Investigador Científico) in March 2010. -
