Prior to coming to Brown University in 1999, he was the Nortel Chair in Emerging Technologies and James Ham Chair in Optoelectronics, and the Director of Nortel Institute of Telecommunications at the University of Toronto.
A Fellow of AAAS, APS, Fulbright, Guggenheim, IEEE, and InstP (UK), Professor Xu is interested in nanoscale science and technology, quantum electronics and photonics, sensors, semiconductor lasers, electro-optics, and collective behaviors of large coupled systems such as neuromorphic computing. His ongoing research includes carbon nanotubes; diamond nanowires, Silicon lasers, active metamaterials, quantum materials, synthesis and non-lithographic fabrication and study of quantum-arrays made from metals, superconducting, molecules and semiconductors; DNA conductivity; physics of redox processes in proteins and cells.

Research results have been reported in over ~330 refereed journal papers and at over 320 plenary, keynote, invited talks at conferences, seminars, colloquia, and speeches in the areas of nano and quantum structures, photonics and physics in USA, Canada, and other regions and countries. Holds 22 patents. Supervised 25 Ph.D theses, 30 Master Degree theses and 26 postdoctoral fellows. 26 of former and current students won 29 international, national, and university awards and prizes for their research accomplishments. 7 of them hold Chaired Professorships. Served and serving as advisers and on advisory boards and committees of government agencies, labs, and companies and firms in USA, Canada, Korea, France, and China, and as DVS (Distinguished Visiting Scientist) of NASA JPL, Telecom Industry Distinguished Visiting Professor of POSTECH (Korea), WCU (World Class University) Professor (visiting) of Seoul National University (Korea), Professeur Invite' of CNRS/Universite of Lille (France), Chang-Jiang Chair Professor (visiting) of UESTC (China), Fulbright-Tocqueville Distinguished Chair.
