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.

About my research: I am mainly working on Cataclysmic Variables (CVs). These are close interacting binary stars, with the primary component (the more massive one) being a white dwarf, and the secondary component usually being a late-type (K-M) star, that is on, or at least close to, the main-sequence. The latter star transfers matter via Roche-lobe overflow into the gravitational regime of the primary star. Depending on the strength of the white dwarf's magnetic field, this matter is accreted by the primary either via an accretion disc, or via accretion columns that form along the magnetic field lines (in case of a strong field). While I have dabbled in several aspects of CV research, my current interest concerns their evolution, and specifically the role of the nova eruption in this.

About my research: My main research areas are the evolution of close compact binary stars and protoplanetary disks. In both fields I combine theoretical modeling with observational surveys to constrain crucial parameters. For details see links to protoplanetary disk and compact binary star group.
