This study tests whether behavioural problems at a young age are related to early reading and mathematics development.

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.

A convolutional neural network (CNN) is a biologically inspired algorithm, highly capable at processing images and videos.

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…

Circulating in Brazil's social media today are many vicious attacks against presidential candidate Luiz Inácio Lula da Silva, known simply as Lula. Widely and enthusiastically shared memes humiliate Lula by depicting him as a poor, uneducated drunkard who deserves to be in jail, thus criminalizing his…

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…

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)…

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.

Parliaments in democratic systems serve as the people’s representatives, legislators and overseers of the executive. They have the power to define the framework in which the executive can act and must report about its action. For parliaments to fulfil their roles, though, they depend on access to information.…
