At a place such as a university where many people communicate and interact on a daily basis, differences of opinion and conflicts are not always avoidable.
Luckily, problems or complaints can often be resolved when the people involved communicate with each other. In the unlikely event that an independent mediator is needed or wanted by a doctoral student, the "ombudsperson" of the faculty may be contacted. Please note that the faculty (dean's office) can often contribute and is able find solutions beforehand.
The ombudsperson for our faculty will be named shortly.
