Background

I have been working since 2020 on R+D+I projects focused on cybersecurity and artificial intelligence, with a particular emphasis on securing infrastructures, systems, and information.

My work spans the design and implementation of cybersecurity systems, including software architecture, system integration, and the development of data-driven security solutions. I contribute across the full lifecycle of research projects, from building core components to integrating heterogeneous systems and validating solutions in real-world environments.

In addition to software and research activities, I design and manage experimental infrastructures for cybersecurity and AI research. This includes the deployment and operation of a private OpenStack-based cloud HPC environment, as well as the setup and maintenance of specialised laboratories such as an Internet of Medical Things (IoMT) lab and a 5G testbed. My responsibilities cover the full stack, from hardware acquisition to system administration, configuration, and long-term maintenance.

My research has primarily focused on user and entity behaviour analytics (UEBA) and risk modelling, and is currently evolving towards the security of AI systems. As a PhD candidate, I am working on Securing Knowledge Distillation of Transformers in Edge and Federated AI with Lightweight Defences, analysing multiple threat scenarios and evaluating the effectiveness of different defence mechanisms.
