Sam Bowden

Sam Bowden is a NRC Postdoctoral Research Associate in the Electron Physics Group.  He received a B.S. in Electrical Engineering from the University of Massachusetts, Lowell, and a Ph.D. in Engineering Sciences with a focus on Material Science from Dartmouth College.  His doctoral research focused on magnetic cellular automata systems based on the exchange interaction and on the enhancement of the longitudinal magneto-optic Kerr effect.   At the CNST, Sam is working with John Unguris to image domain structure in nanomagnetic devices using SEMPA.
