Chaoyun SONG (IEEE Senior Member, IEEE AP-S Member, IEEE MTT-S Member) received his BEng. MSc (with distinction) and PhD degrees all in electrical engineering and electronics from the University of Liverpool, Liverpool, UK, in 2012, 2013 and 2017, respectively. 

  He is currently an Associate Professor (Senior Lecturer) in the Department of Engineering at King's College London, UK. Prior to this, he was an Assistant Professor for 3 years in the School of Engineering and Physical Sciences at Heriot-Watt University, UK. He has authored/co-authored more than 100 papers in leading journals and conference proceedings, including 43 papers in IEEE Transactions. His current research interests include flexible and stretchable electronics, wireless energy harvesting and power transfer, rectifying antennas (rectennas), metamaterials and meta-surfaces, and low-power sensors. His research has also been featured in highly impactful publications such as the Proceedings of the IEEE, Nano Energy, Nano-Micro Letters, Advanced Functional Materials, ACS Applied Materials and Interfaces, Materials & Design, and Applied Physics Letters, among others. He has three ESI Highly Cited Papers published in IEEE TAP (2015, 2016) and IEEE TIE (2017). Additionally, he has filed six US, EU, and UK patents, with one patent being commercialized by start-up company.

   Dr. Song has been the recipient of several international awards, including the IEEE AP-S Young Professional Ambassador 2023, IEEE AP-S Raj Mittra Travel Grant 2023, the EW BrightSparks Award for Top 30 UK electronic engineers under the age of 30 in 2018, and the winner of the IET Present Around the World Competition in 2016. He also received the EuCAP 2023 Best Antenna Paper Award out of over 1200 presented papers, and the BAE Systems Chairman's Award in 2017 for his innovation in next-generation global navigation satellite system antennas. In 2018, he was highly commended in three categories - "Energy and Power", "Emerging Technologies", and "Young Innovators" - at the prestigious IET Innovation Awards. Dr. Song has served as a regular reviewer for over 30 international journals, including Nature Communications and >15 IEEE transactions and journals. He has also been a session chair and/or TPC member for EuCAP2018, IEEE AP-S Symposium 2021, IEEE VTC2022-fall, and EuCAP2023. Dr. Song has been a short course lecturer at IEEE AP-S Symposium 2023 and a workshop panelist at EuCAP2023. He has been a guest editor for Wireless Communications and Mobile Computing, IEEE Open Journal on Antennas and Propagation, Micromachines, ePrime - Advances in Electrical Engineering, Electronics and Energy. Currently, he serves as an Associate Editor for Frontiers in Communications and Networks.
