Research interests
My research is centered around physics beyond the Standard Model (BSM). The Standard Model (SM) of particle physics is a very successful theory but it has some inconsistencies and deficiencies. For example, the neutrinos, which are ghost-like particles that reach us from the Sun and beyond the Solar System, are known to have a very tiny mass. The SM, however, does not explain the origin of this mass. Furthermore, around 95% of our universe is composed of entities that are not explained by the SM. One of these entities is dark matter, which seems to gravitate, i.e., it influences the visible matter through the gravitational force. Dark energy is another invisible entity which is not part of the SM. It drives the accelerated expansion of the universe. I’m interested in exploring particle physics models that can explain neutrino masses and dark matter. These BSM models can be tested at the Large Hadron Collider (LHC) as well as at dark matter direct and indirect detection experiments. Furthermore, I’m interested in the connection between cosmology and particle physics models and ways to include dark energy into the whole picture.
