During this last year, most of our efforts and involvement in terms of recruitment activities and events as well as connecting with prospective students, parents and schools has all been moved online. Not a big surprise – this has been the shift for the entire world.

A number of European countries have started evacuating their citizens and there is a threat of military intervention by neighbouring countries: the situation in Niger is deteriorating rapidly. A military coup has thrown the country into turmoil, partly aided by social media.

A night sky of more than 40 petabytes in size, simulating young star clusters and understanding how the body inhibits viruses: three Leiden projects have received computing time on one of the national computer systems.

Bird, butterfly, fish: when you look through a children’s book, you usually don’t think about the fact that humans divided these animals, depicted in bright colours, into categories. Yet, this division has been discussed for centuries. In her PhD dissertation, Didi van Trijp shows how natural scientists…

Connecting worlds, enhancing research and teaching, and providing innovative solutions to complex social issues: that is the idea behind interdisciplinary research. In that respect, a huge amount happened at Leiden University in 2023.
