BIO SKETCH

My research centers around theoretical and applied aspects of knowledge representation and cognitive technologies. My approach leverages on a hybrid framework where ontologies are integrated with cognitive architectures, which attempt to capture computationally the invariant mechanisms of human cognition (control, learning, memory, adaptivity, perception and action).

In particular, my research at CUPS Laboratory focuses on modeling decision making in cyber security to perform complex simulations of cyber operations (encompassing the actions of attackers, defenders and users, etc.). While a good portion of my work could be qualified as applied research, I try as much as possible to rely on strong theoretical foundations.

Prior to working in the School of Computer Science, I was affiliated to the Department of Psychology (2010-2014) of Carnegie Mellon University. I received a Ph.D. in Cognitive Science (2006) from the University of Trento (Italy), in co-tutorship with the Institute of Cognitive Sciences and Technologies of the Italian National Research Council. I worked at the ISTC-CNR's Laboratory for Applied Ontology (Trento unit) from 2000 to 2010. I was a Visiting Research Associate at Princeton University in 2005 and 2006, under the supervision of Dr. Christiane Fellbaum and Prof. George A. Miller.

I’ve worked for a short period of time as a computational linguist at Cogito, a spin-off of Expert System, world leader in semantic intelligence.

TEACHING

Ontologies for Security and Privacy [Fall 2015]

Ontologies can provide a powerful support tool for security analysis: inasmuch as “data" are the essential bedrock of human decision making, situational awareness can only emerge from “knowledge", namely from a comprehension of the underlying data model. In computer science, ontologies are models that represent the underlying semantics of data: they can be used in a variety of applications, from Search Engine Optimization (e.g., the Google Knowledge Graph), Knowledge Discovery (the Gene Ontology is used in bioinformatics to characterize patterns of interactions within genomic data), NLP (e.g. word-sense disambiguation) and more traditional AI and common-sense reasoning. This course has the purpose of introducing ontology modeling and reasoning, with a specific focus on cyber security and privacy. Basics for implementing and querying ontologies with Protégé platform will be provided. Students will learn the core features of W3C standard computational languages RDF, OWL, and SPARQL as well as the role that semantic technologies play in the Big Data age.
