Ph.D. ​Mechanics and Materials, Columbia University, 2012

Dr. Xu joined the Department of Mechanical and Aerospace Engineering at The University of Virginia in the fall of 2014. He received his PhD in Mechanics and Materials from Columbia University in 2012 under the supervision of Professor Xi Chen. He then came to the University of Illinois at Urbana-Champaign as a Beckman Postdoctoral Fellowship working with Professor John A. Rogers on flexible and stretchable electronics and devices.
