"On October 1, 2017, I retire as an university lecturer. Therefore, I will no longer supervise Bachelor or Master theses, as well as postdoc positions and will not offer new jobs. Current PhD studies and research projects (DFG and industry) will be supervised by me until completion in the coming years. For this reason, I will also continue to work in the research area beyond the 01.10.2017 at the university and will be available as an adviser." (Prof. Dr. Stefan Spange)
