Two talented academics from Leiden who recently obtained their PhD have been awarded a Rubicon grant by the Dutch Research Council (NWO). The grant enables them to gain experience at a knowledge institute abroad.

Cryogenic memories, antibiotic treatment for urinary tract infections and recycling plastic sustainably. These are the subjects of the three NWO-XS grants awarded to Leiden Science researchers.

The university is home to many pearls of research institutes that do not make the news every day. The Executive Board visited one such pearl, the Institute of Philosophy, on Tuesday 1 July. It resulted in an inspired conversation.

On Wednesday 5 November, Jasper sets off on the annual study trip for the Board of Deans together with the Executive Board. Because of budget cuts, they’re staying a bit closer to home this year. But that doesn’t make the trip any less enjoyable — as you’ll read in this column.
