Andrew Balk

Andrew Balk is a CNST/UMD Postdoctoral Researcher in the Nanofabrication Research Group. He received a B.S. and a Ph.D. in Physics from Penn State. His graduate research used low-temperature Hall effect measurements to probe the nanoscale flexing motion of magnetic domain walls. Andy joined the CNST in 2012 to work with John Unguris developing new measurement methods based on Scanning Electron Microscopy with Polarization Analysis (SEMPA) to elucidate the magnetic properties of nanoscale patterned thin films and magneto-electronic devices. He is currently working with Samuel M. Stavis and John Unguris to develop new methods combining nanofabricated devices and superresolution optical microscopy for characterizing magnetic nanoparticles.
