Sharing his passion for sustainability with students—that’s what Thijs Bosker enjoys most about his work. As an environmental scientist, he conducts ecotoxicological research, but next to this he loves teaching. ‘Everyone can make a difference in their own way.’

A job thanks to COVID—something not many people can claim. But PhD candidate Vera Arntzen can. Over the past four years, she has mapped two crucial characteristics of SARS-CoV-2 infections.

‘Leiden is small, friendly and welcoming,’ says new first-year student Ayla Russel.

But fortunately the showers – apart from one – fell somewhere else,…

Xander Tielens, Professor of Physics and Chemistry of the Interstellar Space, has been awarded an ERC Advanced Grant to study polycyclic aromatic hydrocarbons (PAHs) in space. The combination of astronomical observations, computer models and lab research makes the research highly interdisciplinary.

The world let Rwanda down at the time of the genocide, and that can never be allowed to happen again, Cleveringa Professor Roméo Dallaire declared in his lecture on 26 November.

During the spring of 2021, a group of eight biology students from Leiden set out into the dunes in search of amphibians. Using DNA, they determined the geographic origin of the animals.

Now that war is once again raging in Europe, the question of when you need to stand up against injustice has become more relevant than ever. In his Cleveringa lecture on 24 November historian Gert Oostindie will discuss why colonial domination was not regarded as an issue in Leiden for a long time.

Streptomycetes are similar to moulds, but these bacteria live in the soil. They are very popular in biotechnology because they produce a great many antibiotics and enzymes. Gilles van Wezel will be using his Vici subsidy to study ways of increasing their production.

Two deans: one leaving and one just arriving. Paul Wouters was deputising at the Faculty from March up to December. As of January he returns to his 'ordinary' role as dean of the Faculty of Social Sciences. Jasper Knoester is taking over from him, as he will be leaving Groningen for Leiden. How did…

Students, first-time buyers, parents with stay-at-home children, migrants in need of a house; the problems in the housing market affect many layers within the society. The lack of housing is a growing problem. How does this affect our behaviour and the way we think about 'living' ? What are the consequences…
