Prior to his current position, he worked as Research Intern at Ericsson and Huawei Research Labs in 2005 at Karlskrona, Sweden. He received his MSc and PhD degrees in Electrical & Electronic Engineering from Blekinge Institute of Technology (BTH) Karlskrona, Sweden and University of Aveiro, Portugal in 2006 and 2011, respectively. Dr Shahid MSc and PhD were funded by Swedish government and FCT Portugal. He has been involved in several EC R&D Projects (5GPP-Speed-5G, CoDIV, FUTON, C2POWER, GREENET, GREEN-T, ORCALE, ROMEO, FP6, and FP7) in the field of green communication and next generation wireless systems. In EC projects, he holds the position of technical manager, where he oversees the project from a scientific and technical side, managing all details of each work packages which gives the maximum impact of the project's results for further development of commercial solutions. He has been also involved in two Portuguese funded projects (SmartVision & Mobilia) in the area of networking coding and development of system level simulator for 5G wireless system. Dr Shahid has several years of experience in 3GPP radio systems research with experience in HSPA/LTE/LTE-A and strong track-record in relevant technology field, especially physical layer technologies, LTE cell planning and optimization, protocol stack and system architecture. Dr Shahids research interests lie in the field of architectural enhancements to 3GPP networks (i.e., LTE-A user plan & control plan protocol stack, NAS and EPC), 5G related technologies, green communications, cognitive radio, cooperative networking, radio resource management, cross-layer design, Backhaul/fronthaul, heterogeneous networks, M2M and D2D communication, and baseband digital signal processing. Dr. Shahid has more than 60 publications in international conferences, journal papers and book chapters. He is serving as a Vice-Chair of IEEE 5G Standardization. In 2012, Shahid was awarded an "Alain Bensoussan" fellowship by the European Research Consortium for Informatics and Mathematics (ERCIM) to pursue research in communication networks for one year at the VTT Technical Research Centre of Finland. He is also an editor of three books and served as guest editor for a special issue in the IEEE Wireless Communications Magazine and IEEE Communication Magazine. Recently, he is appointed as permanent associate technical editor for IEEE Communication Magazine, IEEE Journal of IoT and Elsevier Journal of Digital Communication and Network. He has been on the technical program committee of different IEEE conferences, including Globecom, ICC, and VTC, and chaired some of their symposia. He was the workshop chair in many conferences and recipient of the 2006 IITA Scholarship, South Korea. Dr. Shahid is a Senior IEEE member.
