Research

Broadly, I am interested in ergodic theory, probability theory, and functional analysis as it can be applied to solve questions in quantum information. 

Currently, I work on disordered open quantum systems, applying the theory of ergodic quantum processes (aka, repeated interaction quantum systems, aka, quantum collision models) to solve problems.
