Did he dare take a gamble with his PhD research? Jeroen Methorst didn’t have to think long about it. It could fail or turn out very well. The latter is the case. Methorst developed a computer system that helps researchers find the protein they need. ‘Our whole group is now using this program.’ Methorst…

Secret services are engaging in increasingly extreme forms of cyber espionage. But nobody talks about this. Dennis Broeders knows why and is trying to have an open conversation about new forms of espionage. As Professor of Global Security and Technology, he will give his inaugural lecture on Friday…

Effectively treating a severe case of pneumonia is often challenging. Identifying the pathogen behind it can be difficult. PhD candidate Ilona den Hartog tried something new: ‘We searched for answers in substances our own body produces.’ PhD defence on 17 September.

How do you get fit after these challenging times? How do you actively start a healthy lifestyle? Healthy University Leiden would like to address these topics during the upcoming from #COVID to #GOFIT Week, which will take place from 21 to 25 June 2021.

De crèche en het klaslokaal zijn misschien wel de meest gunstige plekken voor ziekteverwekkers.
