Research Interests

The goal of Professor McGreevy's current research is to find physical applications of string theory. There are two, wildly different, ways in which this might happen. One possibility is that string theory will be useful in its capacity
as a short-distance completion of models of physics which include gravity. Some areas of inquiry for which such a UV completion is useful are:

• the resolution of singularities and the ability of the topology of spacetime to change;
• models of cosmological inflation;
• mechanisms for supersymmetry breaking and its mediation;
• and many other ideas about physics beyond the Standard Model.

The second possibility arises via holographic duality, an amazing equivalence between string theory in some backgrounds and ordinary quantum field theories
of the kind used to describe many interesting, real physical systems. Through this correspondence, there exists the exciting possibility that results of some laboratory experiments may have a useful description in terms of gravity in extra dimensions.
