As Professor of Translational Neuro-oncology, Marike Broekman researches how brain tumour treatment can be improved. She will discuss this in her inaugural lecture along with her work as a neurosurgeon and the importance of a positive workplace culture.

Biologist Marcel Schaaf is one of four science faculty members who achieved the Senior Teaching Qualification in Leiden last year. How was that and what drives him? ‘Students receive way too often feedback that they cannot put into practice.’

Confetti, stilt walkers and the new Einstein Fountain. On Monday, 2 September, the Gorlaeus Building of the Faculty of Science was festively opened. Together with Constantijn van Oranje, our students cut the ribbon. Dean Jasper Knoester: ‘The building is ready, now it is up to our students and researchers…

Researchers need to work in specialized environments when they work with dangerous bacteria and viruses. These microbes spread easily, so only in labs with a high biosafety levels they can be studied. Unfortunately, to look at the microbes properly, expensive microscopes are needed that are not always…

From global warming to the decolonisation of knowledge. At the EuroScience Open Forum (ESOF) in Leiden over 500 speakers from 60 countries have come together to discuss the big themes of our times. Why have the delegates come?

David Versluis successfully simulated an infant gut virtually. This is crucial for research on improvements in formula milk. Currently, such research primarily relies on diaper contents, which is not optimal. Versluis defended his doctoral thesis on April 23.

For the International Day of Women and Girls in Science, women students and researchers from physics talk about what inspires them about their work. From quantum to cosmology and biophysics, their curiosity about how nature works is what connects these women. What do these 5 scientists want to share…

Why does a medicine work well for one person, but cause side effects in another? Research by Laura de Jong shows that it’s not just our DNA that matters – other medicines and illnesses can also affect how our bodies respond.

Studying how single DNA molecules behave helps us to better understand genetic disorders and design better drugs. Until now however, examining DNA molecules one-by-one was a slow process. Biophysicists from Delft University of Technology and Leiden University developed a technique that speeds up screening…

Moving an electron microscope of 2000 kg is a delicate challenge. The highly sensitive instrument needed to be moved to a new measurement hall, but even a tiny bump could damage it.
