In order to keep personal contacts to a minimum, it is strongly recommended to work from home as much as possible (Allgemeinverfügung des Landes SA). That means that experimental research of the RTG groups is limited to obligatory processes to protect yourself and your fellow human beings at least until 5 April 2020.
To support PhD students who are now impaired in their work the Deutsche Forschungsgemeinschaft DFG offered the opportunity to extend projects of the RTG (DFG-Schreiben). To get more information to the effects of the coronavirus pandemic on the work of the DFG visit: DFG website.
