Xiong Qihua

Associate Chair
School of Physical & Mathematical Sciences
Nanyang Technological University


Dr. Qihua Xiong is currently Nanyang Assistant Professor at Nanyang Technological University. He holds a joint appointment between School of Physical and Mathematical Sciences and School of Electrical and Electronic Engineering. Prior to joining NTU, he worked as a postdoctoral research fellow in the laboratory of Professor Charles Lieber at Harvard University. Dr. Xiong finished his B.S. degree in Physics at Wuhan University in 1997. After obtained his M.S. diploma in physics from Shanghai Institute of Applied Physics, Chinese Academy of Sciences (CAS) in 2000, he went to United States of American with a scholarship support to pursue his Ph.D. research. In 2006, he received his Ph.D. degree in materials science at The Pennsylvania State University under the supervision of Professor Peter Eklund. His thesis research work focuses on fundamental physical properties especially on phonon properties of semiconductor nanowires. During his postdoctoral training, he has extended his research to include high performance nanoelectronic devices based on one-dimensional electron gas in nanowire heterostructures and nanoelectronic devices for single molecule biosensing. Dr. Xiong received several awards and fellowships during his graduate and undergraduate studies, including Pan-American Advanced Studies Institute (PASI) fellowship (DOE and NSF, 2006), Graduate Award for Academic Excellence (The Pennsylvania State University, 2006), Excellent Graduate Fellowship Award (1998 and 1999, CAS), Hui Kai Fellowship Award (Wuhan University, 1996), Gui Zhiting-Xu Hailan Fellowship Award (Wuhan University, 1995) and Outstanding Student Award (Wuhan University, 1994). He won 2nd round Singapore National Research Foundation Research Fellowship in 2009 and chose NTU as the host institute to carry out his research.
