With a background as a Lawyer, Law Teacher, and Researcher in the Philosophy of Law, fascinated by mathematical logic, which I met due to my philosophy studies in law school, I decided to pursue a career in Computer Science, believing information technology is taking over every aspect of society and every research field.

I obtained a PhD in Computer Science from the Free University of Bozen-Bolzano, Italy, researching ontology-driven conceptual modeling applied to the security domain, under the supervision of Enrico Franconi, Giancarlo Guizzardi, and Tiago Prince Sales.

Currently, I am interested in developing ontologically well-founded and logically rigorous technology solutions for risk management, particularly in cybersecurity.

My research employs an ontology-driven approach to security modeling. In particular, I propose a general theory of prevention based on the Unified Foundational Ontology (UFO) to ground an ontology of security--termed the "Reference Ontology for Security Engineering" (ROSE). These two ontological theories have been applied to analyze and redesign artifacts (D3FEND ontology and ArchiMate language).

Currently, I am working on improving those theories and developing novel applications. I am interested in developing well-founded semantic solutions that are understandable, interpretable, and interoperable by both humans and machines.
