I am interested broadly in the dynamics of quantum systems and devices, and particularly in the dynamics of quantum information — the ways in which the information encoded in quantum states scrambles and becomes inaccessible as time passes. How information gets scrambled in realistic physical systems, and how scrambling can either be mitigated or harnessed for useful tasks, are questions that motivate much of my research. The bulk of my work is at the interface between quantum statistical mechanics and quantum information theory; some of it reaches farther afield, to computer science, data compression, approximation theory, etc. In the course of my research I collaborate with experimentalists in photonics, atomic physics, and condensed matter physics.
