I am (Full) Professor of Security and Privacy Enhancing Technologies at University College London (UCL). I am affiliated with the Computer Science Department and currently serve as Head of the Information Security Research Group and Director of the Academic Center of Excellence in Cyber Security Research (ACE-CSR). Before joining UCL in 2013, I was a Research Scientist at Xerox PARC.

I am also a Faculty Fellow at the Alan Turing Institute and on the Technology Advisory Panel at the UK Information Commissioner’s Office (ICO). In 2016, I co-founded the International Data-driven Research for Advanced Modeling and Analysis Lab (iDramaLab).


Overall, I do research in the broad information security area. Recently, I have been doing a lot of work at the intersection of machine learning and privacy, as well as on understanding and countering cybersafety issues using measurement studies and data science.

My research has been published at top-tier conferences such as IEEE S&P, NDSS, ACM CCS, WWW, ICWSM, ACM IMC. My co-authors and I have received best/distinguished paper awards from NDSS 2018, ACM IMC 2018, and CyberSafety 2019, as well as the Data Protection by Design Award from the Catalan Data Protection authority, and were runners-up for best paper at ACM IMC 2014, ICWSM 2017, the 2018 CSAW Europe Applied Research Award, and the 2019 INRIA-CNIL Privacy Protection Award.

  • Joined the PC of S&P 2021


I was born in Avellino, a small town in South of Italy on the green hills of Irpinia. Irpinia is known for its landscapesmedieval castles, hazelnuts, black trufflestorrone, 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 top wine journalist). I have spent six awesome years in California before moving to (pre-Brexit) London. I have also lived in Venice, Rome, Portsmouth, Heidelberg, Singapore, Grenoble, Lausanne, and Barcelona.

In my free(?) time, I like acting as a coffee snob and anti-pineapple pizza radical, remembering (with melancholy) the times I used to surf San Onofre, cooking (only pasta and pizza, obviously), and planning trips with my better half Darya and little one Maya. I am fluent in English, French, Italian, and can utter enough words to get out of (or in, most of the times) trouble in German, Spanish, and Farsi.
