Objectif

The conjecture that there exist in nature extra (i.e. more than four) dimensions, is well motivated theoretically and promises surprising experimental signatures when the extra dimensions and quot;open up and quot;. Liberating our universe from four dimensions, offers new perspectives to long-standing problems of high-energy physics and cosmology. My research project will focus on three areas of interest in the cosmology of extra dimensions. Firstly, I will study the explanation of the smallness of the vacuum energy of the Universe (i.e. the cosmological constant problem) through extra dimensional theories. Secondly, I will study the cosmology of the moduli fields, corresponding to the sizes and shapes of the extra dimensions, mostly in relation with their stabilization. Thirdly, I will study the extra dimensional models, which predict modifications of gravity at large distances, as an alternative to the dark energy paradigm. In the above studies I will work on the theoretical consistency of the theories and propose possible observational signals.
