The Collaborative Research Centre 900 was founded in 2010 and is currently in the third funding period. The CRC 900 contains a total of 20 projects, divided into the four areas A, B, C and Z1 and led by 25 project leaders. An additional central area is devoted to the administration and coordination of the SFB. All relevant decisions are first addressed by the executive committee, made up of nine members. Executive committee meetings take place regularly once a quarter. Additionally, a general meeting is held twice a year, at which all members of the CRC 900 are present.
