I’m a physicist. My interests include condensed-matter/solid-state physics and quantum information science and technology. The merger of these two fields creates opportunities for new physics and technology, such as quantum computers. I work to advance these goals in various roles. I also have a long-term interest in the impact of science and technology on society.
This site serves as a repository for academic work and in no way represents the views or opinions of anyone but myself. Following tradition, most of this site will be very out-of-date.
About Charlie
aka C-DAWG, Batman, Dr. Worldwide, Citizen Charlie.
I currently work at Microsoft Quantum. I’m also a Visiting Research Professor at the University of Maryland-College Park.
Formerly I was Assistant Director for Quantum Information Science and Director, National Quantum Coordination Office, at the Office of Science and Technology Policy in the White House; and Chief Scientist and Chief of Solid-State and Quantum Information Science at NSA’s Laboratory for Physical Sciences.
