Xuhui (Jeff) Sun received his B. Sc. and M. Sc. Degrees from the Department of Chemistry, Tsinghua University, China, in 1993 and 1996, respectively. He received his Ph. D. Degree from the City University of Hong Kong in 2002 under the directions of Professors N. B. Wong and S. T. Lee at City University of Hong Kong, Professor T. K. Sham at University of Western Ontario, and Professor Boon K. Teo at University of Illinois at Chicago. His Ph. D. thesis focuses on the synthesis, characterization and surface chemistry of the semiconductor nanomaterials. After a postdoctoral fellowship with Prof. T. K. Sham at University of Western Ontario where he did synthesis and electronic structure studies of low dimensional metal and semiconductor nanomaterials, he joined the Center for Nanotechnology at NASA Ames Research Center in 2005 as a postdoctoral scholar with Drs. B. Yu and Meyya Meyyappan, doing research on nanowire based nanoelectronics for computing and information storage technologies. He also has a broad research interests with regard to nanoscience and nanotechnology, including the synthesis, characterization, and applications of nanoscale materials (one-dimensional semiconductor nanomaterials and carbon nanotubes in particular) and the development of synchrotron radiation techniques, etc.
