  • About

    I am a PhD student in the Information Security Group at UCL. I joined UCL in September 2015. My supervisors are Professor George Danezis and Dr. Sarah Meiklejohn. My PhD is funded by the EU project Panoramix.

    My research interests are focused on information security and privacy, with particular emphasis on anonymous communication, mix-networks, traffic analysis and analysis of privacy and security.

    Before joining UCL I studied at the Faculty of Fundamental Problems of Technology at Wroclaw University of Technology under the supervision of Marek Klonowski.
