Research Interests

I am interested in studying collective effects in quantum matter. Specifically, I investigate the role that topology, symmetries, geometry, and interactions have on the existence of topological phases in insulators, superconductors, and other synthetic metamaterial platforms, such as photonic or acoustic crystals.

If interested in collaborating or in learning more about our research group, feel free to write to me at I currently have one postdoctoral opening, and one or two graduate student openings. Additionally, I have projects for undergraduate students who are proficient in Mathematica, Matlab, C++, or Python.
