Leiden University aims to create a safe environment where everyone feels comfortable and no one experiences unacceptable behaviour. Should students experience this nevertheless, there are various resources that you can refer them to.

All staff are entitled to a workplace free from unacceptable behaviour such as bullying, sexual harassment, intimidation, discrimination and violence at work. The same applies to integrity issues such as theft or a conflict of interest. If you experience or witness such behaviour or suspect a breach…

During an evacuation, all employees and students gather at the front or backside of the Pieter de la Court Building.

Today, 13 May 2024, Leiden University’s Executive Board is publishing the advice of the committee that investigated reports of unacceptable behaviour and breaches of academic integrity. These reports were about a professor from the university and their partner (a former member of the university staf…

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…

A professor from Leiden University has subjected various colleagues to intimidating and unacceptable behaviour for a longer period. These are the findings of an investigation carried out by the University’s independent Complaints Committee for Unacceptable Behaviour at the request of the Executive Board…

During Consent is Key Week, we’re exploring ways to eliminate sexual violence within our university community. We spoke to Assistant Professor Mischa Dekker, who specialises in gender-related violence, about how to prevent unacceptable behaviour among students and staff.

Silke Herms is a PhD candidate at the Institute of Public Administration.

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…

Melanie Franse works as a PhD candidate at the Institute of Education and Child Studies of Leiden University. Melanie focuses specifically on the biopsychosocial profiles of juvenile delinquents to identify the different mechanisms underlying the development of delinquent behavior in adolescents.

I am passionate about aquatic ecology, conservation and evolution, behavioural biology and global change. During my PhD, I am investigating the density and diversity of pelagic fish in and around offshore windfarms in the North Sea, more specifically related to the underwater acoustic conditions. This…

Anouk is a lecturer and a PhD candidate at the Institute of Political Science.

In his research, Van Gestel focuses on fundamental and applied research on health behaviour and behaviour change in an interdisciplinary context. He focuses on understanding the factors important for health behaviour (behavioural determinants) and on behaviour change techniques as building blocks of…

Cognitive biases affect how we perceive the world every day, but do they influence animal perception too? In my PhD project, I will study the cognitive biases in the acoustic perception in multiple species, to understand their origins and which role they play in the species-specific communication.

After researching inequity aversion in dogs and bonobos during her bachelor’s and master’s projects, Kia Radovanović conducted a study on cross-species pupil mimicry in dogs at the CoPAN Lab.

The gas prices now exceed 300 euros per megawatt hour – a record. The transition from fossil (natural gas, coal, oil) to renewable energy is needed and soon. But how do you get a society (and its citizens) to switch to sustainable energy?

Simon Otjes is assistant professor Dutch Politics.

Bianca Boyer is an associate professor in the unit of Developmental and Educational Psychology. She studies the effectiveness of treatments for children and adolescents with neurobiological developmental disorders, particularly ADHD and Autism Spectrum Disorders.

My research focuses on the acoustic diversity of the marine environment, how it shapes the ecology of marine animals, and how sensory pollutants can disturb the behaviour of acoustically active animals.

I am interested in coping with stress, on both the behavioral and the physiological level of biological function. I am predominantly working with zebrafish, but also other species in the field. My approach is multi-disciplinary and integrative, including molecular biology, morphology, biomechanics and…
