Research Interests

Dr. Wisbey research intersts include materials for quantum computing, microwave resonators and amplifiers, and neutron detectors. Currently Dr. Wisbey is using coplanar waveguides as a tool to probe different materials including defects in Si(100), boron nitride, and graphene. Noise in electronics is a fundamental issue that occurs in many different areas including 2D materials and superconducting circuits. Dr. Wisbey uses his backgroudn in surface science to address important questions about materials used in quantum computing.
