As a result of the Russian invasion of Ukraine, the German Research Foundation (DFG) has suspended all activities within the framework of German-Russian cooperation. The DFG is aware of the consequences of this step and deeply regrets having to take it for the repercussions this has on science. Our solidarity is with the academics in Ukraine who have to fear for their lives and are forced to flee from their homeland, as well as with our long-standing cooperation partners, academics at Russian research institutions, who are themselves horrified at the actions of the Russian government.
