Research Overview:    

My research centers on fundamental questions in physics: What is mass? Why is there any matter at all in the universe? What sets the scales and details of the forces observed in nature? In that vein, I study ideas that go beyond the “Standard Model” of high-energy physics. My particular interests are in the physics of the Higgs boson, a hypothetical (but now found?) particle whose existence is required by the Standard Model so that all other particles can have masses. Closely related, I study supersymmetry, a proposed symmetry of nature which connects the fermions (matter) to the bosons (force carriers)  in a mathematical framework which  is present in superstring/M-theories. Thus the discovery of supersymmetry, or SUSY as it is known, would radically challenge our standard view that objects and the forces that act on objects are somehow distinct, and it would be our strongest evidence yet for the existence of a more fundamental string theory that unifies gravity and quantum mechanics in an 11-dimensional spacetime. The job of finding SUSY now lies with the upgrade of the Large Hadron Collider at CERN in Geneva, Switzerland, to be completed in early 2015.

I also work on related topics in cosmology, including the source of the dark matter and dark energy in the universe, the origins of inflation in the early universe, and the effects of extra space dimensions on early universe cosmology.
