STRW local: Confidentiality persons

Confidentiality, diversity and inclusion

If you have been made to feel unwelcome or unsafe in the Observatory (or by any person affiliated with the Observatory), please contact a member of the peer support twam ('Observatory Allies') to discuss the situation. The current Observaory Allies are Bernhard Brandl, Huib Jan van Langevelde, Yamila Miguel, Arianne Pen, Pedro Russo, Frans Snik or Xander Tielens. They will handle the situation with the guarantee of anonymity and will be able to provide help how to communicate to the university or HR (if needed). If you are uncertain how to proceed after an altercation, the Observatory Allies can also answer your questions.


Leiden observatory aims to provide a warm, friendly and open environment for astronomers of all gender identities, nationalities, and ethnic and religious backgrounds. This should create a welcoming atmosphere that enables students and researchers to fully develop their capabilities. While this environment should clearly help preventing any inappropriate behavior, it is important that if you notice any unwanted behavior of any kind you take action.

A first action might be to have a chat with our Observatory Allies: Bernhard Brandl, Huib Jan van Langevelde, Yamila Miguel, Arianne Pen, Pedro Russo, Frans Snik or Xander Tielens. Other possibilities for help and advice include the Institute manager (Evelijn Gerstel) and the Director (Huub Röttgering) who serve as Observatory Allies as part of their role. Bachelor and Master students can also always turn to Wouter Schrier (study Advisor). It is also possible to speak confidentially with the Human Resources Advisor, Brigitta de Bruijn: .
