PIER PLUS brings together the Hamburg Metropolitan Region’s key scientific players. At the PIER PLUS Steering Committee, the partners’ leading representatives regularly discuss scientific and strategic issues. In a collegiate and trust-based setting, the committee members work together to identify opportunities for joint action with politices and society. The PIER PLUS Steering Committee has an additional task of defining the PIER PLUS profiles and appointing spokespersons and board members. The PIER PLUS profiles are also represented in the PIER PLUS Steering Committee through their spokespersons and chairpersons.
