Senior Lecturer

Abacws, Room Room 5.67, Senghennydd Road, Cathays, Cardiff, CF24 4AG
Available for postgraduate supervision


I am a Senior Lecturer at the School of Computer Science and Informatics and have been with the Cybersecurity group since June 2022. My professional journey includes roles at Toshiba Research Europe in Bristol, Airbus in Newport, and the University of the West of England.

My research is centred on the intersection of AI and cybersecurity. I investigate the protective measures AI can offer to cybersecurity and how cybersecurity can reciprocally secure AI. I have a particular focus on decentralised, large-scale systems such as IoT and smart cities. Additionally, I explore cybersecurity modelling for complex systems, utilising techniques like Game Theory, Epidemiology Modelling, Viable System Modelling, and System Dynamics. If these areas match your interests, I'm open to collaboration and discussions.

Outside of my professional remit, I have a passion for photography, partake in 10k runs, and enjoy watching anime.

Since June 2022, I have been a Senior Lecturer in the School of Computer Science and Informatics at Cardiff University. I am a member of the Cybersecurity group, where I co-lead the group's industrial engagement. I am also the module leader for the Operating Systems Security module, which is part of Cardiff's new NCSC-accredited Cyber Security and Technology MSc, supported by PwC.

Prior to Cardiff University, I worked as a senior lecturer in the department of Computer Science and Creative Technologies at the University of the West of England in Bristol. My role involved module leadership in a series of modules including Security and Forensic Tools (UGT), Critical Systems Security (PGT) and Final Year Projects (UGT).

I have strong industry experience. I worked for Toshiba Research Europe from February 2020 to June 2022 as a senior research engineer conducting research on the intersection between AI and cybersecurity, as well as research around connected autonomous vehicles. I was responsible for the lab's cyber security research strategy, collaborating with Toshiba's business units, and industrial and academic stakeholders. I was also actively involved in a series of projects, including "CAVShield", a feasibility study funded by Innovate UK (£281,990) on the requirements of a cyber security test and evaluation centre for Connected Autonomous Vehicles (CAVs) and Cooperative Intelligent Transportation Systems (C-ITS), and "SWAN: Secure Wireless Agile Networks", a collaborative project with the University of Bristol funded by EPSRC, GCHQ, Toshiba and Roke. Additionally, I led research project bidding activities including SYNERGIA (Secure bY desigN End to end platfoRm for larGe scale resource-constrained Iot Applications) for which I was the technical leader and system architect. Funded by Innovate UK (£2.2M) under the 2020 "Demonstrators addressing cyber security challenges in the Internet of Things: round 2" call, SYNERGIA focused on the end-to-end security of large-scale resource-constrained IoT applications that rely on Edge processing. The project involved the development and demonstration of cyber security research innovations around: i) AI-based intrusion detection at the Edge, ii) secure communication of sensor devices (Endpoints) with other Endpoints and the Edge, iii) secure configuration management of Endpoints and their dataflows at the Edge and iv) the development of the IoT platform's back end.

I also hold a patent on the "Detection of Model Attacks in Distributed AI", published in May 2022, which focuses on a method to mitigate model attacks in Distributed AI architectures using a decentralised approach.

My industrial experience also includes my employment as a cyber security research engineer at Airbus Group Innovations in Newport in 2015, where I was involved in research around threat detection for Industrial Control Systems.
