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.
