I work in theoretical gravitation and cosmology. In gravitation, my interest is the study of the motion of particles (neutral and electrically charged) in different space-times, putting special attention on the classical tests of the general relativity to compare it with availables observational data. In cosmology, my interest is the study of the dynamic behavior of the universe at different epoch, especially in the inflationary era and the accelerated expansion regimen, using alternative models which are tested using the most current data available.
