Research Specialization

High-precision laser spectroscopy of atoms; Experimental tests of Quantum Electrodynamics and the Standard Model; Antimatter, especially antihydrogen and positronium; Exotic states of matter; Laser cooling and atom trapping.

I conduct antimatter research with the aim of producing and trapping large numbers of antihydrogen atoms. Comparing the atomic structure of antihydrogen and hydrogen provides a direct comparison between matter and antimatter atoms and a strong test of fundamental symmetries in nature. I am also comparing measurements of positronium, an electron bound to an antielectron, to test the predictions of quantum electrodynamics theory.
