Description of research and teaching

My research focuses on semiautomated reputation-based trust management for inter-enterprise collaborations. I have defined and experimented on the TuBE trust management system architecture and data model in my PhD thesis, with the goal of designing a system for making trust decisions that can easily be adjusted to different and changing business situations. In the core of each trust decision is a reputation-based assessment of the risk of participating or continuing in a given collaboration, which is weighed against the risk tolerance of the decision-maker. I am also involved in a research project to support trust management in cloud services.
