My research involves understanding the most basic building blocks of matter. At this point, we have a pretty good idea what matter is made of (quarks and leptons, at its base), but we don't really understand the relations between the parts or, in the language of particle physics, the symmetries that govern our current best theory. Some of the questions we are struggling with are: What is the origin of mass? Why is there a discrepancy between the number of matter and antimatter particles in the universe? What is the reason for the masses of the experimentally observed particles? Are the four forces we know about (gravity, strong, weak, electromagnetic) actually all manifestations of one unified force? How does gravity fit into quantum mechanics?
This is an exciting time in particle physics: we have started taking data with the LHC and are exploring an energy regime never before created in the lab. In the next few years, we will see what the TeV energy scale holds. The first data will be the most interesting -- come join us!
