Research interests: I research computer security, privacy, and in particular anonymous communications, traffic analysis, statistical inference, smart metering and peer-to-peer security. I have a special interest in the application of modern machine learning to security problems, as well as distributed ledgers. You can see my full CV and a short bio.
Group: Within the Information Security group, I currently supervise Jamie Hayes, Raphael Toledo, Ania Piotrowska, Marios Isaakidis, Vasilis Mavroudis and Mustafa Al-Bassam. At UCL, I also collaborate with Luca Melis and Sebastian Meiser.
Research positions & PhD supervision: I am an active researcher in computer security and privacy, and always on the lookout for talented post-doctoral researchers and doctoral (PhD) students to join our group at UCL. Interested candidates should email me with a copy of their Curriculum Vitae and a short research statement.
Teaching, thesis and project supervision: I teach two classes for the UCL MSc in Information Security, namely Computer Security I (GA01) and one of the few Privacy Enhancing Technologies (GA17) courses in the world. I am keen to supervise undergraduate or MSc projects on security and privacy, and have some project ideas. My office hours relating to taught courses are integrated within the lecture series (as a fourth optional hour-long slot), and I am available for one-on-one meetings with students and tutees, on request by email.
Funding and other activities: My research has been funded by the EU, the EPSRC, MSR, ACE (GCHQ), UCL and the BIJ. I sit on the board of the PET Symposium, and the ACM CCS and IH&MMS steering committees. I am a fellow of the Cambridge Centre for Science and Policy, and on the advisory board of the Simply Secure Project and Privacy International. I am open to short-term consultancy engagements around computer security and privacy research, or design reviews, through UCL Consultants.

Before joining UCL I was a researcher at Microsoft Research Cambridge from 2007 to 2013. Between 2005 and 2007 I was a post-doctoral visiting fellow at Prof. Bart Preneel's COSIC group at K.U.Leuven, Belgium. With Claudia Diaz we were coordinating the COSIC Privacy Group. Until 2005 I was a research assistant in the Security Group, of the Computer Laboratory of the University of Cambridge, working on anonymous communications, peer-to-peer networks and censorship resistance where I got my Ph.D under the supervision of Prof. Ross J. Anderson. I received my B.A. (Hons) in Computer Science from Queens' College.
I completed my Ph.D. at the Computer Laboratory of the University of Cambridge. My supervisor was Prof. Ross J. Anderson, in the security group. My doctoral thesis entitled Better Anonymous Communications and the associated technical report Designing and Attacking Anonymous Communication Systems (UCAM-CL-TR-594) are available.
