"My field of research is the observational Astronomy, in which I am interested mostly in photometric and spectroscopic studies of Be stars. These are very interesting objects that, despite to have been discovered more than a century ago, are yet under investigation. The special behavior of Be stars, that are irregular variables due to the formation an dissipation of a circumstellar decretion disk around them, has been called the Be-phenomenon.

My research on Be stars has the aim to provide observational data analysis that contribute to the understanding of the formation and disipation processes of these disks, and to the dependence of the Be-phenomenon on the metallicity.  To do that, I use observational data obtained through my own observing proposals, in telescopes of Mexico, Chile and Argentina. I also use existing data in several databases.

Other fields of my interest, in which  I am doing or have done investigation are  searches for variable stars within large databases using supervised learning techniques. Other topics are brown dwarfs, astrometry, and stellar clusters."
