I am a Research Associate at the Centre for Research in Computing of The Open University. I joined the Open University in October 2013, and have been working on the advanced research grant Adaptive Security and Privacy funded by European Research Council. My current research interest is (i) adaptive privacy for online social networks, and (ii) adaptive differential privacy on time-series data (e.g., smart meter, Fitbit data).
I received my Ph.D. from the School of Electronics and Computer Science at the University of Southampton, under supervision of Professor Vladimiro Sassone and advice of Dr. Sardaouna Hamadou. While at ECS in Southampton, I was affilliated with the Academic Centre of Exellence in Cybersecurity.
My research focuses on Security and Data Privacy. I am interested in studying agents' selfish/cooperative incentives in peer-to-peer networks as well as the design of cooperation mechanism with the help of Game Theory and Mechansim Design Theory to make systems run as planned/designed. The application that I have been investigating is anonymity networks (e.g., Tor). I have also interested in the enhancement of security, performance of anonymity networks.
My research also has an angle in data privacy, especially data anonymisation.
My new research interest is adaptive privacy and personalised privacy. In particular, I have been looking at how to engineer adaptive systems that can continuously satisfy the changing privacy requirements of its users. The application that I have been investigating is
(I) Online social networks: help OSN users pick the right audience at runtime;
(II) Time-series data: propose a new definition, Adaptive Differential Privacy, which extends the original definition of differential privacy by considering users' privacy requirements and contexts; propose an obfuscation mechanism for releasing time-series data (e.g., smart meter readings, health data, IoT sensor data, etc.) to guarantee privacy and maintain data utility at the same time.
My research draws from sub-dicplines of Comupter Science such as theoretice computer science, agents and game theory, software engineering.
Game Theory and Applications, Intelligient Systems, Network Security, Data Privacy.
Right now, I have the pleasure to work with a number of amazing people, including colleagues at the Open University.
