Core facilities (CF) at research institutions grant access to sophisticated technologies and equipment to the scientists. Shared resources, managed and supervised by dedicated experts/staff members, lead to an overall improved research infrastructure. But new challenges need to be faced to run these CF´s in a sustainable and legal fashion. Within this GerBI chat, we will give an overview in legal frameworks and financing strategies. Two experts from the GerBI workgroup 2 (“Financial & Legal Framework of Core Facilities”), Juliane Hoth (TU Dresden) and Elmar Endl (Uni Bonn) will start with a presentation that will later open up into an open discussion round. During the chat, participants can vote for future topics within this planned GerBI Chat series (e.g. cost calculation in depth, …) to be discussed in more detail.
