Ian Gilbert is an NRC Postdoctoral Researcher in the Electron Physics Group. He received a B.S. in Applied Physics from Grove City College in 2010 and a Ph.D. in Physics from the University of Illinois at Urbana-Champaign in 2015. His doctoral research involved fabricating and measuring arrays of single-domain ferromagnetic nanoislands (known as "artificial spin ice") to experimentally investigate the behavior of frustrated Ising spin systems. Ian’s current research is focused on the electrical control of magnetism. He is working with John Unguris to use scanning electron microscopy with polarization analysis to study spin-orbit torque switching of magnetization in heavy metal/ferromagnet bilayers and magnetization rotation in artificial multiferroic heterostructures. Ian is also interested in the microscopy of thin film magnetic skyrmions.
