Research Interests :

General Relativity and other theories of gravity:

- Black holes, wormholes, cosmic strings and shells.

- Electrodynamics in topologically non trivial geometries.

Time variation of fundamental constants:

- Statistical Analysis of Observational Data

- Predictions of Theoretical Models: Bekenstein, Damour-Polyakov, Olive-Pospelov, etc

- Comparison between Data and Models using statistical analyses

Cosmic Microwave Background:

- Theoretical Predictions of non-standard cosmological models: varying constants, non standard inflation, etc

- Statistical Analysis using latest CMB data in order to test the above mentioned models.
