Staff Profile Overview

I joined the Department of Computer Science, Cardiff School of Technologies, Cardiff Metropolitan University (Cardiff Met) in October 2020 as a Lecturer in Computer Security. Prior to my joining Cardiff Met, I worked from February through July 2020 as a Post-Doctoral Research Associate on a £7.2m European Union funded Federated Cyber-Range project for Aviation, Power and Navy, known as H2020 FORESIGHT federated Cyber-Range project. I also worked briefly as an Associate Lecturer in 2019 after my PhD at the Cyber Security Research Group of Edinburgh Napier University. My PhD was completed in 2019 on a programme known as RESCUE: Evaluation of a fragmented secret share system in a distributed cloud-based architecture, through which I developed a prototype of a data-sharing method known as Fragmented Secret Share System (F3S). The thesis also produced two evaluation frameworks to measure scalability and resilience of cloud-based data sharing methods as part of its results. My most recent work has involved evaluating new methods of cryptography that has solution in creating a foundation layer of data protection using new methods of supporting the management of encryption keys within cloud-based systems using threshold and functional cryptographic systems.
