General Research Areas

I am  interested in application of Topological Defects in distint areas. For example, I have investigated:
* The domain networks as a possible candidate to explain the present accelerated expansion of the universe.
* Cosmic strings, magnetic monopoles and other compact objects  as source of space-time variations of the fine-structure constant, $\alpha$, in the their vicinity.

Recently, I have started to focus on Topological Defects in Condensed Matter. In this context, I am interested in liquid crystal.

I am also interested in scalar fields models and observational constraints of the dark energy .
