If we need funding for a project, equipment or research at the university, we automatically think of the Dutch Research Council or other grant providers. But more and more researchers are managing to connect with people who care about the university.

We asked a lot of everyone last year. The Personnel Monitor showed that the workload was high in 2022 and Covid took its toll. I therefore think everyone deserves some downtime. Time away from the daily grind.

This week we can vote in the University elections. The University Council and faculty councils are incredibly important. During the fantastic seminar on 50 years of participation that the University Council recently held, our former Rector Carel Stolker aptly said: ‘Without participation, there would…

We know more together than alone. To increase our university’s impact on the region, we have to be open to the world outside. This is how we strengthen our ties and create new opportunities for teaching and research.

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 recently went to the anniversary celebration of The Meeting Point, and the stories the refugee students told made a huge impression on me. The Meeting Point helps students from different backgrounds feel part of our university community.

Ever since its foundation, Leiden University has turned its gaze outwards to other cultures, languages and forms of academic practice. It is only natural, therefore, that we as a university have four institutes abroad: the Royal Netherlands Institute of Southeast Asian and Caribbean Studies (KITLV-KNAW)…

Leiden University is a fantastic example of a network university: we create an impact with the city, stakeholders and regional and international partners. The lines of communication are really short and there is a great sense of togetherness. Our good relations with the city have also informed how we…

On International Women's Day (8 March) we take time to consider female emancipation and participation. What does this day mean for Leiden University, and how does it tie in with our aim of becoming more diverse and inclusive? We talked about these issues with Annetje Ottow, who recently became the…

Leiden University will set up further activities with the Asian Development Bank (ADB).

During a meeting at the University on 10 November, staff spontaneously removed a painting by artist Rein Dool from the wall in one of the meeting rooms in the Academy Building, reversed it and placed it on the floor. A tongue-in-cheek action with a serious undertone. This has led to a lot of commotion…

Annetje Ottow, president of the Executive Board of Leiden University, has been the new chair of the Leiden-Delft-Erasmus (LDE) strategic alliance for just two months. What does she want to achieve during her two-year chairmanship?

Timo Kos has been Vice President of Leiden University’s Executive Board since 1 March. Who is he and how have his first weeks been? ‘Higher education is under threat; we’re under fire.’

Leiden Mayor Peter Heijkoop visited the Faculty of Social and Behavioural Sciences and the Faculty of Science on Monday,

Collegevoorzitter Luc Sels ontvangt van de Universiteit Leiden 2 juli een eredoctoraat van de Universiteit van Edinburgh.

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…

How do you achieve the structural change needed for a more inclusive university community? What challenges do female staff face in their careers and what does it take to be a woman in a leadership role? This is what over 40 female staff members from the university discussed on International Women’s…

The number of insect species is plummeting, which is why the University is creating a more biodiverse environment around its buildings. Annetje Ottow, President of the Executive Board, planted the first bee-friendly plants in the front garden of Oude UB on 20 September.

Research into our history of colonialism and slavery, heart-to-heart conversations at a Keti Koti table, exhibitions, lectures and podcasts that establish the link between present and past. Staff and students participated in the national Slavery Memorial Year in many different ways. What have we learned…

The rising energy prices cannot have escaped anyone’s notice. They have dominated the news in recent months. As a university, we too face a big challenge as the prices continue to rise. We will all have to do our bit in the coming months, also in view of the climate crisis that we want to help resol…

Black-and-white photographs filled with solemn young men and distinguished professors line the walls of the Grand Auditorium. Young women are missing from the photos; women rarely obtained PhDs 50 years ago. And this article is about that group, the PhD candidates between 1966 and 1972, who were invited…

This is the Board of Advisors of CompaRe.

With the six pieces of the puzzle now assembled by the partners of the University Campus and the Mayor of The Hague, Jan van Zanen, the building at the Spui was officially opened last Thursday.

A lot is going on in the world right now, and our university regularly faces big issues and dilemmas too. Then it can be tricky to switch off. For me, exercise is a way to unwind. We want our staff to be able to relax too and are therefore offering various events and workshops that should help.

One of the good things about my job is that I come into contact with so many different alumni. It’s incredibly important that we build good relationships with our alumni from a young age already. We can help our graduates develop skills and grow their network, and they in turn can help our organisation…
