The Steering Committee (SC) supports the Executive Board and GBN in the implementation of the work programme and ensures that the biobanks of the German Biobank Alliance (GBA) work together effectively. The committee decides on GBA matters and shapes the strategic direction. Until 2020, the SC consisted of the heads of all partner biobanks of the GBA and the IT development centres as well as Prof. Dr Michael Hummel for GBN. The rapidly growing number of biobank partners since 2019 (and -Observer since 2021) made it necessary to reduce the size of the committee. Since 2020, a new 12-member SC has been elected every two years.
In the 2024-2025 term of office, the steering committee is consisting of the following members Dr Heidi Altmann, Dr Gabriele Anton, Dr Ronny Baber, Dr Daniel Brucker, Prof Dr Thomas Illig, Prof Dr Roland Jahns, PD Dr Michael Kiehntopf, Dr Romy Kirsten, Prof Dr Martin Lablans, Prof Dr Alexandra Nieters, PD Dr Sara Nußbeck and Dr Alexandra Stege. In addition to the 12 elected members of the SC, Prof Dr Michael Hummel attends the SC meetings as a permanent guest in an advisory role.
