I am an information physicist at Oak Ridge National Laboratory (ORNL) within the Center for Engineering Science Advanced Research and the Complex Systems Group, both of which are components of the Computer Science and Mathematics Division (CSMD) in the lab's Computing and Computational Sciences Directorate (CCSD). Please use the ORNL phonebook to find my contact details.

My research focuses on theoretical and experimental aspects of information. Quantum information, a theory of information derived from the laws of quantum physics, is of particular interest. My efforts are mainly in the development of quantum computation and communication protocols with optical systems (especially teleportation). I also investigate the use of quantum control techniques for atomic and molecular systems as well as quantum-based sensing strategies.

As part of this research, I investigate forms of quantum communication that may one day supplement or replace existing methods for sharing information. This research involves understanding how pairs of entangled photons can be created by a process termed spontaneous parametric down conversion (SPDC). These entangled photons are prepared by pumping a nonlinear optical crystal with an intense laser pulse. The incoming light then 'down converts' into a pair of photons. By tuning the pump and crystal properties, the generated photon pair can be entangled in their various degrees of freedom, e.g., polarization, frequency, etc. These entangled states are the basis for demonstrating quantum communication protocols, such as quantum teleportation.
