A strong co-operation, including projects where Prof. Hollert is acting as PI or Co-PI and main supervisor of several PhD-candidates, is vital with his former Department of Ecosystem Analysis at RWTH Aachen University, which is now headed by Dr. Martina Roß-Nickoll (Deputy professorship). Dr. Miaomiao Du and Dr. Sebastian Heger are acting there as team leaders. Thanks a lot for this great partnership! Please have a look into the projects to learn more on the ongoing joint projects.
