Research Interests

My main research interests include theoretical and astrophysical aspects of cosmology, gravitational physics (extensions of General Relativity) and cosmological effects and field theory of solitons in the context of particle physics. One of the main goals is to learn about fundamental physics by studying scenarios for the structure and evolution of the universe. I am also interested in applying new technologies (computational techniques) in both research and teaching.
