I work at the intersection of quantum many-body physics and quantum information. My particular interest lies in the dynamics of quantum information in many-body systems, with a focus on understanding the informational "phases" of matter which can be generated in non-equilbrium settings. I also like working with tensor networks, as both a conceptual and numerical tool for studying quantum phenomena.
