University is often a period of sexual exploration and experimentation, generally to the satisfaction of all involved. But sometimes you want it and the other doesn’t. Or vice versa. Or you can’t really tell. This is what the Safe Space play at Theater Ins Blau was about on 11 October. And: can your…

It is sufficiently plausible that, during her employment, a professor of archaeology at Leiden University was guilty of prolonged transgressive and unacceptable behaviour, ‘which also at that time could be classed as unacceptable’.

The Executive Board of Leiden University has appointed Dr Tom Louwerse as Professor of Political Behaviour and Research Methods at the Institute of Political Science.

This is a difficult time. Above all, for all those directly involved in this horrible case – unacceptable behaviour by a professor and his removal from the University – the case we went public about on 18 October and that has been reported in the media. This is painful and tough for the complainants…

I suggest a systematic study into the influence of non-singing female companions on vocal learning in young birds as a proof-of-principle study into how non-imitative learning processes from the social environment influence the timing and content of vocal learning and thus drive the interface between…

I am a Postdoc and research the interactions between our gut microbes and the brain i.e. the science of ‘that gut feeling’. I am fascinated by the trillions of bacteria that inhabit our bodies and in particular the ways in which they may interact with our brain to influence our mood and behaviour. Bidirectional…

A professor from Leiden University, together with a former employee (who is also the professor’s partner), has been guilty of long-term unacceptable and often transgressive behaviour in the form of abuse of power and manipulation. This behaviour led to a culture of fear among staff who were largely…

It is sufficiently plausible that the professor from the Faculty of Archaeology exhibited the ‘inappropriate and unacceptable behaviour’ detailed in the advice of the investigating committee. That is is unless the professor provides counter-evidence. This is the conclusion of the Subdistrict Court…

The past year was once again a year of outstanding achievements and strong engagement for the Faculty of Social Sciences. In this hall of fame, we proudly highlight a selection of awards, grants and appointments as part of the many valuable contributions — visible and behind the scenes — that together…

Studying how single DNA molecules behave helps us to better understand genetic disorders and design better drugs. Until now however, examining DNA molecules one-by-one was a slow process. Biophysicists from Delft University of Technology and Leiden University developed a technique that speeds up screening…
