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. Very 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.

News:
Along with Marius Junge, Felix Leditzky, and Thomas Sinclair, I am organizing the workshop ``QLA Meets QIT II'' to be held in Chicago 3-5 November. More information can be found here https://sites.google.com/view/qlameetsqitii/home and the poster is here /media/717
In the Spring term 2023 I will be running an undergraduate research project on quantum channels and error correction.
