His current research is driven by the Large Hadron Collider (LHC), the highest energy particle collider in the world, currently operating near Geneva Switzerland. The LHC is the first direct experimental probe of the Terascale, the physics of elementary particle interactions with energies of order TeV (about 1000 times the proton mass energy). The physics that can be tested at the LHC is extremely rich, including the breaking of electroweak symmetry and generation of mass for elementary particles, as well as the prime candidate for the origin of dark matter.
