Short Bio

I am a Reader (Associate Professor) in Security and Privacy Enhancing Technologies at University College London (UCL), where I am affiliated with the Computer Science Department and the Information Security Group. Before joining UCL in 2013, I was a research scientist at Xerox PARC. I received a summa-cum-laude Laurea degree in Computer Science from the University of Salerno, Italy (2005), then, in 2011, a PhD in Networked Systems from the University of California, Irvine, advised by Gene Tsudik. My dissertation, titled "Sharing Sensitive Information with Privacy," can be found here. During my PhD, I also spent a few months on research internships at NEC in Heidelberg (2008), INRIA in Grenoble (2009), and Nokia in Lausanne (2010).

Overall, I do research in security and privacy enhancing technologies. These days I work on understanding and countering security issues via measurement studies and data-driven analysis, as well as tackling problems at the intersection of machine learning and security/privacy.

Research Group

I am extremely lucky to collaborate with a number of people at UCL and elsewhere, and proud to supervise:

Working with me

Please send me a short (and personal) email with your CV, the names of 2-3 references, and 2-3 paragraphs summarizing your research interests, whether you have funding, and whether you have already contacted someone in UCL's Information Security Group, if you are interested in:

  • Applying for a PhD or post-doc under my supervision. If I don't have specific openings announced, you could find information about scholarships for outstanding students on this page. We also have funding through the Security Science Doctoral Training Center and the Alan Turing Institute
  • Being hosted at UCL on research visits or fellowships. There are several opportunities for fellowships, including with the EPSRC, Royal Society, Marie Curie, Fulbright, etc.

Teaching Activities


I was born in Avellino, a small town in South of Italy surrounded by the green hills of Irpinia. Irpinia is known for its beautiful landscapes, medieval castles, hazelnuts, truffles, torrone, and some great wines like Taurasi, Fiano di Avellino, and Greco di Tufo (which I know of only thanks to my brother Paolo who is a terrific wine journalist). I have spent six awesome years in sunny California (4 in Irvine and 2 in Palo Alto), before moving to pre-Brexit London. I have also briefly lived in Venice, Rome, Portsmouth, Heidelberg, Singapore, Grenoble, Lausanne, and Barcelona. In my free time, I like acting as a coffee snob, pretending to be akin to a movie critic, remembering (not without melancholy) the times I used to surf in San Onofre, cooking (pasta and pizza of course), and planning trips with my better half, Darya. I speak English, Italian, and French, and can utter enough words to get out of (or in, most of the times) trouble in German, Spanish, and Farsi.
