The IRTG invited all members to a Doc´s meeting in the evening in Leipzig. The purpose was to refresh the doctoral connection, adopt finished Docs, and socialise our IRTG community after long corona isolation. Furthermore, we said goodbye to Sebastian and thanked him for his excellent cooperation as the doctoral representative. He will finish his doctoral thesis in Autumn 2021. Newly elected Isabell Kazmarek will follow in his footsteps.
