About my research: In collaboration with Claus Tappert and an international workgroup I am carrying out a project for recovering classical Novae,  more than 30 years after their eruption, by using spectroscopy and photometry on the remnants, determining orbital periods and other essential parameters to better understand the relation between Novae and other subclasses of cataclysmic variables.  I am also leading another international project that analyzes observations of the cataclysmic binary TT Ari, obtained with the Canadian Space Telescope MOST in 2007 and 2012. Together with our students I am obtaining and analyzing our own observations of post-common envelope binaries (PCEBs) and other types of variable stars. In addition, we are utilizing the ASAS data-base in order to investigate properties of pulsating Mira stars, as well as the behavior of long-term variables with low amplitude.  -  In collaboration with astronomers of the Universities of Jena and Hamburg, Germany, I am carrying out research on young stars of low mass. This project is based on observations made with the NACO instrument of Paranal Observatory (ESO) which allows infrared photometry, high-angular resolution, and precise astrometry of stars in star forming regions and their companions and their stellar and substellar companions (brown dwarfs and planets).

Teaching: Introductory course in astronomy, optional courses (astrobiology, variable stars); undergraduate seminars and dirección of thesis in Master program of Astrophysics.

About my research: My main research areas are the theory of gravitation and cosmology. In gravitation, my interest resides in the study of the motion of particles (neutral and electrically charged) across different space-times, putting special attention on the classical tests of the general relativity to compare it with availables observational data. In cosmology, I focus on the study of the dynamic behavior of the universe at different epochs, especially in the inflationary era and the accelerated expansion regimen, using alternative models which are tested using the most current data available.

Teaching: Classical Mechanics, Statistical Mechanics, Waves and Optics; Laboratory of electromagnetism; Cosmology; General Relativity; Nuclear Physics; Physical Processes in Astrophysics.
