With its EU Liaison Office, the Berlin University Alliance (BUA) joined UnILiON (Universities Informal Liaison Offices Network) at the beginning of 2021. The BUA liaison office in Brussels builds on the experiences of the existing liaison offices of Freie Universität Berlin and Technische Universität Berlin. It offers researchers better access to and faster integration in EU-focused international research networks. Dr. Angelika Wilhelm-Rechmann is the coordinator of the BUA EU Liaison Office.

UnILiON is a voluntary association of currently 50 Brussels offices of universities, representing 156 universities in Europe, Japan, and Russia. The network is a platform for exchange on which the members cooperate, exchange ideas, and network and act as multipliers for the organizations represented. The members of the network are involved in several working groups that meet regularly, and they organize a wide range of events. For example, lunch talks on current topics, brokerage events, or annual conferences. UnILiON is often successful in attracting top executives to their events in Brussels: For example, Christian-Silviu Busoi, MEP, Chairman of the Committee on Industry, Research and Energy of the European Parliament, and Jean-Eric Paquet, Director General for Research and Innovation, have been speakers at UnILiON.
