From 1994 to 2002 Nina Wels studied animation at the Academy for Film and Television in Potsdam-Babelsberg. In the following years she worked as an animator for various television and cinema productions, as 3D animator for "Lissi und der wilde Kaiser" ("Lissi And The Wild Emperor", 2007) and as chief animator for "Jasper und das Limonadenkomplott" ("Jasper: Journey to the End of the World", 2008) among others. Together with Thomas Bodenstein, she then co-directed the first adaptation of the children's book character "Ritter Rost" (2012), which was a great success with the public.
