I am originally from the Twin Cities area. After graduating with my B.S. in Physics from Bethel University in 2012, I joined the Physics PhD program at the University of Minnesota where I have been working in Professor Paul Crowell's research lab since the summer of 2012. Primarily through electrical transport techniques, I have studied spin-related phenomena in a variety of material systems including combinations of semiconductors, ferromagnets, and non-magnetic metals.

Summary of Interests
spin injection, spin relaxation, 2D spin transport, spin-Hall effect, ferromagnetic resonance, spin pumping, spin transfer torque
