About

Bio

Brian is a NASA Postdoctoral Program Fellow working on various aspects of quantum capacitance detectors, a type of far-IR/THz detector based on superconducting qubits. He was a graduate student in physics at University of California, Santa Barbara, where he worked on microfabrication of optomechanical devices and manipulation of their quantum state. He was an undergraduate student in physics at the Massachusetts Institute of Technology, where he wrote his thesis on spin chains in solid-state NMR for quantum information. In his free time, he practices judo with the Pasadena Kodokan Judo Club, and homebrews beer and mead.

  • M.A. in Physics, University of California, Santa Barbara (2010).
  • S.B. in Physics w/ minor in Mathematics, Massachusetts Institute of Technology (2008).

Research Interests

terahertz radiation, superconducting qubits, MEMS/NEMS devices, optomechanical devices, quantum information
