I am broadly interested in the Internet of Things (IoT), systems engineering, and the security of cyber-physical systems. Most of my current work is in the field of smart cities e.g. urban sensing and energy-efficient deployments of wireless sensor networks, design of secure IoT applications and open data architectures, location and data privacy in mobility applications, sensor integration with building management systems in smart buildings etc. In general, my research addresses questions of how emerging technologies can be used to deliver a more sustainable urban future through resource efficiency, resilience, and operational improvement of infrastructure systems.

I am also interested in applying Systems and cybernetics techniques such as system dynamics and viable system modelling, network analytics and game theory, for information and risk management in this context. I view Systems thinking as a fundamental approach for understanding and dealing with complexity, especially of cities and civic tech.

Finally, I have experience with IT auditing and digital forensics, looking at compliance, governance and the extraction and analysis of digital evidence, particularly from emerging technologies such as mobile phones, wireless sensor networks and social media. On these issues, I have acted in the past as an Expert Witness in a number of court cases.
