Dr. Zhang received B.S. and M.S. degrees in physics from the Nanjing University of Science and Technology  in 1982 and the Chinese Academy of Science in 1986, respectively. He was on the faculty of Shanghai Jiao Tong University between 1986 and 1989. He received his Ph.D. in physics from Syracuse University in 1994, spent 3 years as a postdoctal fellow at Oak Ridge National laboratory/the University of Tennessee  prior to joining the Florida International University as a faculty member in 1998. Starting from 2009, he became a full professor in physics at Louisiana State University.

Research Interest: Experimental Condensed Matter Physics 

One grand challenge in condensed matter physics and materials science is to understand the remarkable properties emerging from complex correlations of atomic and electronic constituents, and to control these properties for technological applications. The complexity in many novel materials is directly responsible for their tenability and consequently their practical functionality. In many cases, Creating surfaces, interfaces, ultra-thin films, and artificial superstructures add the additional twist of “man-made” dimensions, approaching the quantum phenomena of correlated electrons with broken symmetry and reduced dimensionality.

My main research interest is in exploring novel properties of complex materials like transition-metal oxides by the effects of broken symmetry, reduced dimensionality and spatial confinement, and by controlling lattice strain and chemical composition. The research include growing artificially structured configurations of complex materials like transition-metal oxides with atomic scale precision and in-situ comprehensive characterization on lattice structure, chemical composition, electronic and magnetic properties.
