I work in condensed matter theory, specializing in topological phases, quantum information, and classical simulation of quantum systems.

In contrast to Landau’s symmetry classification of matter, where phases are described by symmetry-breaking order parameters, topological phases are distinguished by nonlocal topological invariants.  These phases are fundamentally quantum mechanical with no classical analogue; they are characterized by exotic emergent excitations of the bulk, which are often accompanied by gapless edge degrees of freedoms.  My research is focused on finding materials which support these phases of matter, understanding their properties, and exploring ways that these systems can be manipulated.
