I am a PhD student working in the area of event-based systems. My research is focused on the challenge of defining reactive behavior that needs external information (context). Defining reactive behavior with countless rules is cumbersome and error-prone. Thus, I am researching a method to use policy-driven contextualization.

For example, a company wants to ensure that no visitors enter offices of project leaders. Therefore, it deploys various sensors (cameras, RFID, etc.). If a person is detected at a certain position, the underlying event-based system must check in which room that position is and if that room is an office of a project leader. To do that, the system must also know who is a project leader. Furthermore, the security clearance of the detected person must be checked. This information is not included in the position-detection event.
While all of these steps do not pose hard problems, they must be encoded manually. Thus, I am investigating how events from sensors can be selectively enriched with useful information (contextualized) so they allow for easily checking policies. Hence the name policy-driven contextualization.
At the same time, events sent by sensors must be transformed in a way that albeit different semantics in structure and meaning, the matching against subscriptions is successful and event consumers interpret events correctly.

I am always looking for talented students. If you are looking for a thesis topic or a job, please contact me and we can talk about the details
