How do you study the growth of microorganisms, the spread of epidemic diseases or the healing of wounds, without actually performing experiments? Daoyi Wang, PhD candidate at the Mathematical Institute, worked on a specific mathematical model that can describe the growth of microorganisms and many other…

In the fight for a liveable planet, we desperately need a fairer distribution of wealth and equal rights for all, argues anthropology professor Marja Spierenburg. ‘That will also generate broad-based support for sustainable development.’

Did you know that Leiden University has an active staff association?

An Honours Class about the ostensibly unrecognisable worlds of insular Southeast Asia teaches students a fundamental piece of wisdom: "We do not differ much from the people at the other end of the world."

We know we should do it, and we often want to, but… Why is it so hard to live a healthier life? Professor of Behavioural Interventions in Population Health Marieke Adriaanse explains.

The new institute manager of the IBL studied biology for six months, but went in a completely different direction: development cooperation and the financial sector. Three decades later, Resi Janssen is making a radical career switch. Or isn’t she? 'In ten years’ time I want IBL to be in a new, sustainable…

Your toddler refuses to eat vegetables, your child is being bullied at school, or you’re simply overwhelmed by everything on your plate. How can parents manage these situations effectively? During this Week of Parenting, our researchers and lecturers share practical advice for parents.

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.
