My primary research is particle physics beyond the Standard Model, but I also stray into related areas of high-energy astrophysics and cosmology.

Within particle physics, I am particularly interested in predictions for collider experiments and the interpretation of their results, and my interests in astrophysics and cosmology include dark matter and strategies to detect it, as well as dark energy and cosmological inflation.

Specific research topics include the Higgs boson (or whatever replaces it), searches for it at CERN's Large Hadron Collider (LHC), and its possible connections with matter-antimatter asymmetry and the generation of matter in the Universe. Much of my research concerns supersymmetry, which I consider to be one of the most promising possible extensions of the Standard Model, and I am working actively on searches for supersymmetric particles at the LHC and as astrophysical dark matter.

I am also interested in models of quantum gravity, particularly those derived from string theory, and am in quest of possible experimental probes of such models, either in accelerator experiments or in high-energy astrophysics and cosmology
