Radio Frequency Fingerprint Identification (RFFI)
Identifying and authenticating wireless devices from the unique hardware imperfections imprinted on their transmitted signals.

I am a fully funded PhD student in the CSIT Doctoral Training Programme at Queen’s University Belfast, funded by the UK Government’s New Deal for Northern Ireland. My research develops efficient deep learning and hybrid quantum-classical machine learning for the wireless physical layer, including radio frequency fingerprint identification (RFFI) for authenticating IoT devices, automatic modulation classification, and Wi-Fi sensing. The common goal is to make these models light enough to run on resource-constrained devices in 6G networks.
I am supervised by Prof. Simon L. Cotton (primary supervisor) and Prof. Trung Q. Duong (secondary supervisor).
