Research Interests

My research interests lie within the overlap of quantum information and quantum many-body physics. My recent work has focused on achieving fault-tolerant quantum computation with topological quantum error-correcting codes. I am excited about using numerical techniques and machine learning to solve challenging problems in physics.
