I am an information scientist 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). My research focuses on the theoretical and experimental aspects of information science, including quantum computation and communication, quantum control theory, digital signal processing, and cognitive radio. To contact me, please use the ORNL phonebook.

As part of my research, I investigate forms of communication and computation based on the principles of quantum physics, that may one day supplement or replace existing methods for processing and sharing information. A large focus of my research involves understanding how pairs of polarization-entangled photons created by spontaneous parametric down conversion (SPDC) can be used in protocols for information transfer, such as quantum teleportation and quantum memories. Polarization-entangled photons are readily prepared by pumping a nonlinear optical crystal with an ultrashort laser pulse. The incoming laser light 'down converts' into a pair of photons and, by tuning the pump properties and crystal geometry, this pair of photons can be entangled in their polarization degrees of freedom. These states, often termed Bell states, can then be used in a variety of quantum information experiments.
