About the Editor
Jonathan rodriguez received his MSc and PhD degrees in Electronic and Electrical
Engineering from the University of Surrey, United Kingdom, in 1998 and 2004, respec-
tively. In 2005, he became a researcher at the Instituto de Telecomunicações, Aveiro,
Portugal, and a member of the Wireless Communications Scientific Area. In 2008, he
became a Senior Researcher and was granted an independent researcher role where he
established the 4TELL Group (http://www.av.it.pt/4TELL/), a visionary research group
developing innovation for next‐generation mobile networks, with key interests on green
communications, cooperation, security, radio frequency design and 5G. Since its inception,
the group has steadily grown and now Dr Rodriguez is responsible for managing 36 research
staff, that includes the supervision of 10 PhD students and 10 post-doctoral researchers.
Since 2009, he has become an Invited Professor at the University of Aveiro, where he
teaches specialist modules on wireless communications as part of the integrated Masters
course in Electrical and Electronic Engineering. In 2007, he coordinated the international
Eureka Celtic LOOP project, and was then coordinator for the FP7‐ICT C2POWER project.
He has also served as General Chair for the ACM‐sponsored MOBIMEDIA 2010 (6th
International Mobile Multimedia Communications Conference), Co-Chair for the EAI
sponsored WICON 2014 (8th International Wireless Internet Conference), and was work-
shop chair on 17 occasions in major international conferences that include IEEE Globecom
and IEEE ICC, among others. He is the author of more than 300 scientific works, that include
50 peer‐reviewed international journals, and five edited books. He was responsible for
winning 30 research grants with a project portfolio in excess of 5m €. His professional affili-
ations include Member of IET, Senior Member of the IEEE, and Chartered Engineer (CEng).
