Dr Oktay Cetinkaya (Senior Member, IEEE) is a Lecturer in Sensor Systems at Newcastle University. Before this role, he was a Senior Research Associate and a PETRAS Synthesis Fellow at the University of Oxford. Earlier, he held postdoctoral positions at the University of Sheffield and the University of Southampton. He received his PhD in Electrical and Electronics Engineering and graduated with first-class honours in both Electrical Engineering and Electronics and Communication Engineering (double major) in Istanbul, Turkey.

Dr Cetinkaya's research aims to achieve energy neutrality in the Internet of Things (IoT) and drone networks through energy harvesting, wireless power transfer, transient computing, and low-power communications innovations. His work tackles challenges unique to these networks, including efficient deployment and trajectory design, throughput maximisation, and secrecy outage minimisation, resulting in over 45 co-authored publications.
