Research Interests: 

I work in the field of theoretical atomic physics; my research focusses primarily on tests of fundamental theories. I study the violation of fundamental symmetries in atoms, probing low-energy processes in order to test the Standard Model and Unification theories (GUTs). So-called “new physics” (physics beyond the Standard Model) is sensitive at low energy to the nuclear weak force, which causes the symmetry violation. This work is complementary to that being done at CERN - in fact, parity violation in cesium is the most precise low-energy test of the electroweak theory to date. I also currently work on developing new methods to search for dark matter and dark energy, the composition of which remain among the most important outstanding problems facing physics today.
