Biography

Haixuan Xu earned his bachelor’s degree in Metallic Materials Engineering from the Dalian University of Technology (China) in 2005, and his MS and PhD in Materials Science and Engineering from the University of Florida in 2008 and 2010, respectively. His dissertation research focuses on point defect interaction and evolution as well as their effects on mechanical properties, ferroelectricity, and transport properties of materials using ab initio and molecular dynamics simulations. In 2010, Xu joined Center of Defect Physics in Structural Materials, which is an Energy Research Frontier Center at the Oak Ridge National Laboratory, as a postdoctoral researcher where he worked on new kinetic Monte Carlo methods extending the time scale of traditional atomistic simulations to investigate long-term defect dynamics in advanced structural alloys. In 2013 Xu joined the faculty at the University of Tennessee and is investigating defect evolution and deformation mechanisms in advanced structural alloys, electromagnetic coupling and flexoelectric effects in heterostructured complex oxides, materials for neuromorphic computing, and mesoscale simulations methods, such as the Self-Evolving Atomistic Kinetic Monte Carlo (SEAKMC) approach. Xu has authored or co-authored ~50 technical papers and has contributed to over 20 invited presentations at national and international conferences.
