My main research interests include ultrasensitive laser spectroscopy, optical frequency metrology, and quantum optics using cold atoms. My group is exploring molecular dynamics using exquisitely sensitive absorption-measurement techniques developed in JILA. We also use high-sensitivity techniques to define ultrastable optical frequency standards, currently being explored for their use in metrology, communications, and high-precision measurements such as in NASA's space-borne interferometers. The use of ultrafast lasers has revolutionized the field of optical frequency metrology, and we are actively pursuing research related to the concept and application of this novel field. We are also exploring cold atoms and molecules for their use in high-precision measurement and quantum optics.
