Leiden University’s President of the Executive Board, Professor Annetje Ottow, has been reappointed for a second term by the Board of Governors.

Timo Kos has been appointed Vice President of Leiden University’s Executive Board and will take up the role on 1 March 2025. He succeeds Martijn Ridderbos, who will join the board of the Netherlands Authority for Consumers and Markets (ACM) on 1 January 2025.

‘We may have taken steps together, but there is still much to do in the fight against racism and discrimination’, says Annetje Ottow, President of Leiden University’s Executive Board. ‘We have to be aware of this and continue to focus on this difficult, uncomfortable and often confronting topic.’

After nearly five years as President of the Executive Board, Annetje Ottow will be stepping down from the role as of 1 September. During her time as President, she helped shape the university’s strategic direction, strengthening its regional, European and international profile. Sustainability, and dignity…

Since 1 November 2025, Prof. Dr. Luc Sels has been the new president of Leiden University's Executive Board. In a message to our university he introduces himself and shares his first impressions.

Leiden University has a new Executive Board. Since 8 February 2021, Annetje Ottow has been the new President and Hester Bijl the new Rector Magnificus of the Board, while Martijn Ridderbos has continued in his role as Vice-Chairman.

An article in Leiden University’s Mare newspaper on 24 September states that the University Council advised against reappointing President of the Executive Board Annetje Ottow. The Board of Governors, deans and Annetje Ottow respond below.

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.

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.

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…

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.’

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.

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.

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…

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)…

Now the introduction weeks can go ahead as usual, the new students’ enthusiasm is overwhelming. It’s back to normal for the student associations too, having had a hard time of it during the pandemic.

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…

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.

From human rights in Sudan to a new cult of heroes in China. During the board members' visit, the Institute of Private Law and the Institute for Area Studies clarified their social relevance in no uncertain terms. What's happening here in education and research?

Vice-chairman of the Executive Board Martijn Ridderbos will leave Leiden University at the end of this year.

ChatGPT, the text-generating chatbot, has recently become available for anyone to use. Is this artificial intelligence (AI) tool a threat to our teaching?

Our annual strategic conference was held this year on 15 and 16 June in Soesterberg, and has now become a tradition at our university.

We want to be an engaged community where we feel heard and enjoy working together. But how do we have an open conversation about difficult topics?

Several Dutch universities have said they do not want foreign student numbers to grow any more in some of their degree programmes. They are reaching maximum capacity. We are also alert to this in Leiden, but I see many positive aspects to the intake of international students.

This month the University and several partners signed the rental contract for the brand-new Spui building. What will this location mean for the future of Campus The Hague, Leiden University and the population of The Hague? Martijn Ridderbos explains in his column.

The results of the Personnel Monitor 2022 are out. Now the ball is in all of our courts. What does the Monitor tell us and how can we act on it? I hope that as an organisation we can get a good dialogue going as the first step towards improvement.

People in leadership roles are unlikely to discuss leadership skills with their colleagues. But that is precisely what we as a university would like them to do. Because trust in one another’s abilities will make us an agile university that innovates and makes room for talent.

The more than 370 sensors that have been hung up in Leiden University buildings to count the people present will not be switched on again. The equipment will eventually be removed from the buildings.

Academic freedom is something to be cherished. The freedom to conduct research, design courses and publish research findings as we see fit is crucial to our work.

Within the scope of innovating and connecting – the theme of our new Strategic Plan – I paid a visit to Brussels last week. It is important to give Leiden University a face in Brussels and to show our expertise, on Africa for instance.

If universities and research institutions want to tackle unacceptable behaviour in academia, they must shift their focus from dealing with complaints to preventing such behaviour in the first place. This is what the Royal Netherlands Academy of Arts and Sciences (KNAW) has concluded. It has therefore…

I was disgusted by the recent Ongehoord Nederland broadcast on 15 September. The racist and hateful comments made by alumna Raisa Blommesteijn were, as far as I am concerned, way over the line and in my opinion also violate Article 1 of the Constitution of the Netherlands.

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…

Board members Annetje Ottow and Hester Bijl recently visited the Leiden University Centre for Linguistics (LUCL, Faculty of Humanities) and the Mathematical Institute (MI, Faculty of Science). This was the start of a series of visits to institutes at our university. The focus is on talking to researchers…

The Leiden-Delft-Erasmus Universities strategic alliance celebrates its tenth anniversary in 2022. At the ‘The Next Ten Years’ anniversary celebration in the Faculty Club on 12 April, the partners looked back on their achievements and ahead to the major social challenges of the next ten years.

The world is currently beset by many problems. The armed conflict and continuing violence in Israel and the Palestinian territories is resulting in numerous casualties. This is giving rise to many emotions and reactions worldwide, and also greatly affecting our own university community. We have seen…

There are many links between Leiden and the US. The highest office there has been held an impressive nine times by presidents with Leiden roots. This has led to memorable visits to Leiden University.

Annetje Ottow is the first female president of the Executive Board of Leiden University, which means a return to her Alma mater.

The Schoof cabinet has presented its budget. As expected, higher education is facing severe cuts. In the coming period, the Executive Board will regularly look at the consequences of what it deems an irresponsible policy.

Each research institute has its own dynamic. The Executive Board is visiting our institutes to find out what they are up to. On 24 June, it was the turn of the Institute for History. ‘History helps us make sense the present, whether through family stories, local issues or world politics.’

The Executive Board proposes to take the decision to suspend the existing institutional student exchange programmes with two Israeli universities, and until further notice not to engage in any new exchange programmes with Israeli universities that have comparable links with the Israeli military (the…

Academics increasingly face threats, intimidation and abuse. The WetenschapVeilig platform has been launched to address this.
