Research

My interest in the field of condensed matter physics lie primarily in the theoretical understanding of correlated quantum matter. The topics of my research revolve around a rich set of phenomena in topological superconductors, copper- and iron-based high temperature superconductors, as well as quantum Hall systems, and spin liquids. Through the use of quantum field theory, symmetry group analysis, and large-scale numerical techniques, I hope to further the understandings of new phases of matter and emergent phenomena in strongly correlated systems. I am also interested in the development and implementation of algorithms for large-scale numerical computations on quantum systems.
