Dr. Ruijuan Xu is an Assistant Professor of Materials Science and Engineering at North Carolina State University. Ruijuan received her B.E. from Zhejiang University, her M.S. from the University of Illinois at Urbana-Champaign, and her Ph.D. from the University of California, Berkeley, all in Materials Science and Engineering. Before joining NC State, she was a GLAM Postdoctoral Fellow in the Department of Applied Physics at Stanford University and SLAC National Laboratory. Ruijuan’s current research focuses on the design and manipulation of novel functional properties and exotic phenomena in oxide thin films, heterostructures, and membranes. Her research group leverages atomic-scale epitaxy and state-of-the-art characterization techniques to construct novel ferroic materials, with an emphasis on applications in next-generation microelectronics and energy technologies.
