Research Areas: Cosmology/Particle Physics
My research is in the area of particle physics and cosmology. The main topics on which I work are: big bang nucleosynthesis, which is an explanation of the origin of the light element isotopes through 7Li; particle dark matter; big bang baryogenesis, which is an explanation of the matter-antimatter asymmetry observed in nature; and inflation which is a theory constructed to resolve many outstanding problems in standard cosmology.
