Peng Xiong received his B.Sc. in Physics from University of Science and Technology of China, in July 1987.  He received his Ph.D.in Physics from Brown University in September 1993, with a thesis covering topics of high temperature superconductivity, magnetic granular solids, and mesoscale superconductivity.  He then spent the next four years as a postdoctoral fellow at the University of California at San Diego, performing research in superconductor-insulator transition and fluctuation effects in two- and one-dimensional systems.  He joined the Physics faculty of the Florida State University in November of 1997.  He is a member of the Center for Materials Research and Technology (MARTECH).

His research interests fall into the following three areas:
1. Mesoscale Physics: quantum phase transitions and fluctuation effects in 2D and 1D systems;
2. Spintronics: spin polarized transport in ferromagnet/normal metal, ferromagnet/superconductor, and ferromagnet/semiconductor hybrid structures;
3. Bio-nanostructures: magnetically- and electrically-based nanoscale biosensors, nanoscale bio-mechanical devices.
