Dr Hamed Ahmadi



I am a lecturer (assistant professor) in communications and networks in school of Computer Science and Electronic Engineering at University of Essex, UK. My research interests are Next generation of mobile systems (5G), radio resource allocation, self-organizing networks, small cells, economic models for networks, network virtualization, networked flying platforms, optimization, machine learning, game and auction theory, and evolutionary algorithms. My professional activities: I co-chair network layer working group in COST Action CA15104 (IRACON) actively participate in IoT for health sub-working group activities. I am a member of editorial board in IEEE Access and Springer Wireless Networks. I have been the recent results track-chair of IEEE PIMRC18, tutorial chair of CrownComm18 and Network Softwarization track-chair of EuCNC19. I have also TPC co-chaired Next-GWIN18 and served Next-GWIN16 as summer school chair. I co-chaired 5G-related workshops in IEEE Globecome18, WCNC18 and PIMRC17. My past: In 2008, I received Singapore International Graduate Award (SINGA) to study Ph.D. at National University of Singapore. During my PhD studies, I was an attached student at Institute for Infocomm. Research (I2R). At NUS, I also attended graduate courses in engineering management department as a part of management of technology (MoT) program and received a graduate certificate in MoT. I was a research fellow at CTVR/CONNECT, Trinity College Dublin, Ireland from 2012 to 2015. At CTVR I was working in Prof. Luiz DaSilva’s team and my research focused on game theoretic and machine learning approaches for decentralize dynamic spectrum access and the next generation of mobile communications, 5G. I started working at the School of Electrical and Electronic Engineering University College Dublin as a Lecturer in 2015 where I am an adjunct faculty now.
