Seok-Hwan Chung, Postdoctoral Research Associate

Contact Information

Seok-Hwan Chung is a Postdoctoral Research Associate in the Electron Physics Group in the CNST-University of Maryland Cooperative Research Program. He received a B.S. in Physics from the Seoul National University, Korea, and a Ph.D. degree in Physics from the University of Maryland, College Park. For his thesis research, Seok-Hwan studied the magnetic domains and transport properties of magnetic nanostructures. After receiving his Ph.D., Seok-Hwan was a Postdoctoral Fellow at Argonne National Laboratory, where he developed biosensors using magnetic nanoparticles and studied the confinement effect of magnetic thin films. He is currently working with John Unguris on the fabrication and characterization of magnetic nanostructures with the goal of understanding how their microscopic properties may affect potential applications.
