My research focuses on data privacy and information security and their application to federated systems. I am interested in the design and use of frameworks for privacy risk assessment, the development of provable privacy mechanisms, and the study of utility/privacy trade-off in specific application domains. Some of my recent projects include:

• Privacy-Preserving Analytics for the EdTech Industry
• Private Data Sharing in Trusted Agrifood Exports
• Privacy-at-the-edge systems (e.g. smart electricity meter, mobile data collection, federated ML)

David is a Principal Research Scientist, his research interests include:

• Game theory for distributed networks;
• Distributed optimisation for wireless mesh networks and 5G Networks;
• Smart-grid communications and demand-side management;
• Wireless networks for disaster response;
• Body area networks — technologies and systems.
• Privacy preserving technologies for releasing data, information-theoretic.

Paul is a Principal Research Engineer with an interest in bringing research to the domain of transport and infrastructure. Paul is particularly interested in:

• connected and automated vehicles
• traffic control systems
• data privacy and security in transport environments

My research focuses generally on privacy of mobile and wearable devices (Internet of Things). I aim to identify and combat privacy threats on mobile and wearable devices through the quantification and analysis of user behavioural biometrics. My previous research works include risk measurement and evaluation of critical infrastructures, through threat models and risk methodologies.
