My main research interests lie in the creation, manipulation, and study of cold molecules and their interactions.  Such systems are ideal for a wide array of scientific applications, ranging from tests of fundamental symmetries and the search for new physics beyond the standard model of particle physics to understanding and controlling chemical reactions.
