Personal profile


I am a senior lecturer in computer science at University of Hertfordshire. Before joining Hertfordshire, I was a senior lecturer in cyber security at the University of West London where I held the role of course leader for BSc (Hons) Cyber Security. Prior to West London, I was a research fellow working in the RCUK dot.rural Digital Economy Research Hub at the University of Aberdeen. 

My main research interest lies in the area of access control, computational trust and decision making. Within these areas, I have investigated theoretical questions as well as performed empirical and applied research. My current work focuses on the development of incentive mechanisms for obligation fulfilment, and trust-based data sharing models for IoT. I am also interested in looking at the interaction between AI and security. 

I am currently accepting PhDs working in the areas in line with my research interest. Please get in touch if you would like to discuss your research ideas further.
