The Speaker Team of the AGEP Network is a rotational and voluntary initiative based exclusively on enthusiasm and commitment of the AGEP Network members interested to support sustainability of the network. Currently the AGEP Network is represented by four Speakers – Petra Kohnen, Tiemo Timmermann, Anne Siebert and Bettina Hamann – each representing one of the study programmes from the network. Considering its scope and nature, the AGEP Network would not be able to exist and function without contributions of all initial and current members of the Speaker Team.
