Research Description
My research interests are in operator space theory and quantum information theory. In particular, I am interested in the local structure of operator spaces and operator systems, quantum games, and quantum error correction. Recently I have been interested in quantum field theory, and holography. Graduate students are welcome to email me if you are interested in any of these topics.
