Areas of Expertise
The Standard Model of particle physics (SM), which describes the electromagnetic, weak, and strong interactions of quarks and leptons, has been amazingly successful at explaining data from collider experiments. Yet it has a number of apparent shortcomings. For example, numerous observations provide evidence that the energy density associated with dark matter is much greater than that associated with ordinary matter. The SM cannot explain this fact. Also, the dynamics of the SM tend to drive the scale of electroweak symmetry breaking to be very large, so that to explain the experimentally measured values of the W and Z gauge boson masses requires an extreme (and to many, unbelievable) fine-tuning among certain parameters of the theory. This apparent problem – called the hierarchy problem – has motivated some of the most promising extensions SM. I am interested in ideas for physics beyond the SM, and how they can be tested at the Large Hadron Collider and elsewhere.
