Biography

Dr. Xu is a Reader at the University of Warwick. He received his PhD degree in Optical Communications and Intelligent Signal Processing from the Royal Institute of Technology (KTH), Sweden. He subsequently worked as a Postdoctoral Research Fellow at KTH and RISE Acreo Sweden, and as a Visiting Research Fellow at the Technical University of Denmark (DTU). Prior to joining Warwick, he served as a Senior Research Fellow at University College London (UCL), where he currently also holds an Honorary Lecturer position.

Dr. Xu’s research interests include optical communications, optical sensing, intelligent signal processing, and machine learning techniques. He is a Fellow of the Higher Education Academy (HEA) and a Senior Member of the American Physical Society (APS). He serves as an Associate Editor for IEEE Transactions on Communications and the Journal of the European Optical Society-RP. He has previously served as Chair of the Optics in Digital Systems Technical Group of OPTICA and as a Technical Programme Committee (TPC) co-chair or member for over 20 IEEE conferences, including GLOBECOM and ICC.

Dr. Xu is the Coordinator of two EU Horizon Europe projects, the Project Manager of an EU Horizon 2020 project, and the Principal Investigator of a UK National Grid-funded project, with total funding exceeding £3.8 million as Coordinator or Principal Investigator. He has published over 105 journal papers and 80 conference papers, including more than 30 invited papers, as well as two invited book chapters.
