Quantum optics and atomic physics, including fundamental studies in quantum measurement, conditional dynamics of observed quantum systems, real-time quantum feedback, and closed-loop quantum control.

Optical biophysics, focusing on the use of experimental and mathematical methods from quantum optics to enable biophysical investigations at the few- or single-molecule level.

Current projects:
Our experimental work focuses on quantum measurement and feedback, quantum information science, optical approaches to molecular biophysics. Our laboratory work is guided and supported by theoretical work at the interface of quantum optics with control and dynamical systems. Current scientific interests include:

Continuous, real-time quantum measurements and feedback control of open quantum systems

Interaction of noise, measurement, and dynamics in open quantum systems; implications for the study of quantum chaos and nonequilibrium statistical mechanics

Application of experimental techniques and theoretical methods from quantum optics to the study of molecular and biophysical dynamics
