Research Directions:

• Nanoscale imaging with microwaves: We employ scanning microwave microscopy to visualize electronic states at temperatures down to 60 mK, with the goal of exploring topological edge modes, domain walls, and emergent phenomena across the GHz regime.


• Topological states of matter: We employ microwave imaging to visualize topological states in emerging materials, including magnetic topological insulators, topological semimetals, quantum spin Hall insulators, and van der Waals heterostructures. A long-term goal is the development of methods to experimentally detect states governed by nonabelian statistics.


• Correlations in flat band systems: We aim to realize robust flat bands in moire systems and 3D materials that give raise to strongly correlated electronic states. Of particular interest are novel states of matter that emerge from the interplay of strong interactions and non-trivial band topology, such as fractional topological states and high Chern number insulators.


• Quantum computing based on low dimensional materials: We use nanofabrication and electronic transport measurements to explore quantum phenomena in reduced dimensions and harness topological excitations for quantum computing.


• Quantum nanomechanics: We develop nanoscale devices based on suspended 2D materials, in which electronic behavior is coupled to the mechanical movement of the heterostructure.
