My research is mainly focused on theory and phenomenology of electroweak symmetry breaking (EWSB). While the fact that the symmetry is broken is universally accepted as one of the cornerstones of the standard model of particle physics, the mechanism responsible for this breaking is at present unknown. Several alternative mechanisms have been proposed by theorists. Each model predicts a rich variety of new physical phenomena such as new particles, interactions, and possibly even new compact dimensions of space. I am interested both in constructing new models of EWSB, and in devising strategies for testing them experimentally. The latter area is especially exciting since relevant experiments are currently underway at the Large Hadron Collider (LHC) now under construction in Geneva, Switzerland. Examples of my recent research in this direction include: studying predictions of natural EWSB models for the properties of the recently discovered Higgs boson; proposals of novel strategies to search for supersymmetry and other new physics at the LHC; and a study of the power of the LHC detectors to discriminate among the models with similar signatures, conducted in collaboration with members of the Cornell high-energy experimental group.
