Kun Yang received his PhD degree from University College London (UCL) in the area of communication networks and services. After 3 years' post-doc research in the Department of EEE at UCL working on EU research projects such as FAIN (Future Active IP Networks), MANTRIP and CONTEXT, he moved to University of Essex at 2003 to become an academic staff. Now he is a Chair Professor in the School of Computer Science and Electronic Engineering (CSEE), University of Essex, leading the Network Convergence Laboratory (NCL). His current research activities are focused on advancing new technologies related to communication and network systems, and on the fundamentals underlying them, including communication theory, algorithms, network science, machine learning and edge intelligence. In particular he is interested in energy aspects of future communication systems such as 6G, promoting energy self-sustainability via both energy efficiency (green communications and networking) and energy harvesting (wireless charging). He has published 300+ technical papers and 2 monographs in the above areas. He has been managing research projects funded by various sources such as UK EPSRC, EU FP7/H2020 and industries (e.g., British Telecom).
