From 2017 to 2020, he served as a research associate for a project on AIDS history in Germany at Humboldt University in Berlin. As a collaborative effort between HU and SMU, the Berlin AIDS Oral History Collection emerged. Additionally, he contributed to curating the exhibition arcHIV. eine Spurensuche.

Continuing his voluntary work in the SMU archives, alongside archival duties, his work on the board will primarily focus on program planning and developing a Code of Conduct for the SMU.

Heiner Schulze

is a Berlin based social scientist. He studied at Humboldt Universität in Berlin and has done studies and research residencies at the Sorbonne Nouvelle in Paris, the New School of Social Research in New York City and the University of Agder in Kristiansand, Norway. The focus of his research is in social inequality, HIV/AIDS crisis, trauma and memory, as well as queer history and interventions. He organizes events in academic and artistic fields. Being active in educational politics for many years, he increasingly began to engage with queer politics. Following the traditions of the gay movement‘s drag queens and fairies, he can found at demonstrations wearing high heels as well as on the stage as a part of Tuntenkombo. Before being elected as a board member of the Schwules Museum, Schulze was active as a volunteer in the museum library and archive. Based on this experience, he wants to give more attention to the somewhat neglected library and archive and strengthen links to the community and science. Furthermore, he sees the Schwules Museum as an important social space that is brought to life through events and workshops. As a SMU board member, Schulze wants to further stimulate the development of this social space and help other people and groups to fill the space.

Joachim Schüller

Joachim Schüller moved from Essen, a city in the Ruhr area where he was born in 1956, to Berlin in 2017. Professionally, he works as an educator and has been actively involved in various roles at a boarding school for the hearing impaired in Essen for many years. Additionally, he has contributed to various queer and cultural ideas and projects on a voluntary basis.

Since May 2020, he has been volunteering in the museum service department at SMU. In November 2021, he was elected by his fellow volunteers as the spokesperson for the volunteers in the museum service. In this role, he has been able to leverage his past professional and volunteer experiences to contribute effectively to SMU, including specific projects like organizing the 2023 “Long Night of Museums Berlin” (Lange Nacht der Museen).

Due to his knowledge and skills, he enjoys questioning and, if necessary, optimizing structures, especially to ensure that volunteers at SMU feel appropriately recognized and valued for their invaluable work. His candidacy aimed to directly represent and, understandably, necessitate the representation of volunteerism in the SMU’s board, as it is from this position that necessary impulses can be provided and opportunities created to shape volunteerism at SMU and guide its further development.

His focus within the board is therefore on raising awareness and integrating volunteerism more consciously and robustly within the SMU’s board work, as well as structurally. Furthermore, he aims to concentrate on the museum service area and contribute to organizational development within SMU, actively participating in structural work.

Christan Tillmans

Christian Tillmans – banking and business graduate – spent his professional life at one of Europe’s leading aviation companies. There, he gained management and leadership experience in roles such as sales, revenue management, commercial management, human resources, and executive development.

He completed coaching training and supported the establishment and development of an in-house LGBTQI network.

In September ’23, he concluded his management role and has since been volunteering, including as a coach at “startsocial e.V.” and in job mentoring with “jobs4refugees gGmbH” and “Ulme 35 Interkulturanstalten e.V.”

As a board member, he aims to support the management with his expertise and practical knowledge to further professionalize the SMU’s economic, administrative, and organizational structures and processes. This includes collaborating with the management to devise measures to further enhance the museum’s attractiveness and increase visitor numbers.
