Dr. Guohua Xie obtained his Ph.D. degree from Jilin University (China) in 2011, investigating active matrix organic light-emitting diodes (OLEDs) and demonstrating the first prototype of QVGA OLED microdisplay in China. From August 2011, Dr. Xie carried out his postdoctoral research on high-temperature stability of OLEDs at TU Dresden (Germany), sponsored by Alexander von Humboldt Foundation. From 2013 to 2015, Dr. Xie worked for an interdisciplinary project to determine the spatial coherence of organic light sources at the Organic Semiconductor Center of the University of St Andrews. Since January 2015, he has served as an associate professor at the College of Chemistry and Molecular Sciences of Wuhan University (China). Dr. Xie gained extensive experience in the interdisciplinary research of organic optoelectronic materials and devices. He has coauthored over 180 peer-reviewed publications. In 2020, he was admitted as a Fellow of the Royal Society of Chemistry.
