Research Interests

My research interests lie at the intersection between topological order and quantum information theory. I have been applying concepts in quantum information theory in the studies of topological order. This program has been successful in two different directions. It has led to new insights about topological order, but it also kindled fruitful new questions in quantum information theory.
