Overview
Changcheng Zheng obtained a B.Sc. in physics from University of Science and Technology of China in 2007 and completed his Ph.D. in 2011 (degree awarded in 2012) at the Department of Physics, University of Hong Kong (HKU). After being a research assistant/associate at HKU for more than a year, he worked as a lecturer at Xi’an Jiaotong-Liverpool University from 2013 to 2019. His research is about experimental condensed matter physics: optical properties of semiconductors and nanostructures, exciton dynamics in bulk and low dimensional systems under different excitation conditions, and nonlinear optical properties of novel luminescent/fluorescent materials. He has taught university physics for more than 10 years, completed several external and interanl research projects, and published more than 70 journal papers with co-authors.
