I am interested in Cosmology, which is the study of the origin, evolution and composition of the universe. Cosmology has a very successful standard model, which, however, is unsatisfactory and surely is incomplete. According to the model, most of the matter in the Universe is dark, exotic and only inferred indirectly; also more than 70% of what makes up the universe is something that suggests that some energy is associated with the nothingness of vacuum: "dark energy". Dark energy is one of the major problems in physics today and is motivating a host of future and planned observations. I study the "large-scale distribution of galaxies", their statistical properties and how the emerge and evolve from the Universe's initial conditions, which can be gleaned from  the statistical properties of the heat left over from the big bang. These observations are used to shed light on the Universe composition (including the dark energy) evolution and ultimately the physics governing it.
