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.
