My research program is devoted to the theoretical study of ultra-cold quantum atomic gases and is performed in close collaboration with researchers at the University of Maryland at College Park, the National Institute of Standards and Technology (NIST), and the University of Sheffield in the United Kingdom. Some of my specific interests include ways in which ultra-cold atoms, manipulated by lasers and magnetic fields, can operate as a “quantum computer”; the dynamics of mixtures of Bose-Einstein condensates during the cooling process; and the design of new atom interferometers to increase their robustness, stability, and sensitivity for applications to precision navigation and to metrology.
