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 and was a Beckman Postdoctoral Fellow at the University of Illinois at Urbana-Champaign from 2012 to 2014. 

Dr. Xu’s group research interests are focused on multiscale-multiphysics mechanics-driven extreme design and nanomanufacturing of functional materials, structures and devices for applications in wearable electronics and healthcare, in particular, transfer printing in liquid, solution shearing, soft-hard material integration, solid-liquid functionalized materials, and bioinspired devices and structures. 

Dr. Xu’s group has also been working on nanomechanics at extreme conditions, including mechanics of liquids in nanoconfinements, nanofluidics in response to environments, and thermal transport of mechanically deformed nanomaterials.
