Model-based systems engineering of critical cyberphysical systems necessitates effective collaboration between different collaborators, teams, stakeholders. Engineering artifacts stored in model repositories are concurrently developed in either offline (checkout-modify-commit) or online (GoogleDoc-style) scenario where the confidentiality and integrity of design artifacts need to be protected by access control policies. Unfortunately, traditional approaches for managing concurrent code

My research focuses on developing (i) a general secure collaboration scheme that guarantees that high-level access control policies are respected during collaboration and it can be integrated into existing version control systems (e.g. SVN) to support offline scenario; (ii) automated merging and fine-grained locking to enhance the efficiency of conflict resolution and prevention upon concurrent modification of the models; (iii) derivation and incremental maintenance of view models to provide specific focus of the designers by abstracting from unnecessary details of the underlying system model.
