Research

My graduate research was conducted in Prof. Norman Birge's group at Michigan State University. Our work explored the superconductor/ferromagnet proximity effect whereby there is seepage of supercurrent from a superconductor into an adjacent layer. In a traditional superconductor and ferromagnet system, the opposite spin-pairing of the supercurrent causes an oscillation and a steep decay within the ferromagnetic material. I investigated methods to extend and control this effect.
