Whenever possible, the RTG works safely from home. As all our PhD students are currently in the experimental phase of their PhD, it is increasingly difficult to proceed with scientific work without entering the laboratory. Currently, the 4th regulation for the containment of the spread of the coronavirus is in force (4. SARS-CoV-2-EindV). Public RTG events are still not taking place. Seminars, colloquiums and workshops are suspended. But under strict observance of the regulations the laboratories are open and research can take place tentatively.
