Sounding board groups and partners
Various sounding board groups give their opinion about the course of the programme. Their vision is important, since they already have knowledge about and experience in (innovation in) education. Some of these sounding board groups are also collaboration partners within the University at the same ti…

Expansions of quantum group invariants
In my research, we developed a method to distinguish knots. A knot is a mathematical depiction of the everyday knot that occurs in ropes and cords.

Beenakker Group (Theoretical Nanophysics)
Our world is shrinking, or at least our electronic devices are. From PCs to mobile phones: everything is smaller and thinner. The smaller the chip, the better it can conduct electricity and pass on information.

Governance and Data Science Group
The extensive use of electronic communication channels and other devices has opened new possibilities for collecting data on human behavior. This information is sometimes openly accessible, but largely part of administrative registration systems that are not open to the broader public. The data provides…

Intense automorphisms of finite groups
In this thesis we classify the pairs (p,G), where p is a prime number and G is a finite p-group possessing an intense automorphism, i.e. an automorphism that sends each subgroup of G to a G-conjugate, that is non-trivial and whose order is coprime to p.

Group behaviour: one for the team
Researchers at Leiden study group behaviour. One of their findings is that when people make sacrifices for another member of their group, it is probably instinctive. Insights of this kind enable us to better understand and influence the social processes in a neighbourhood or company.

Collaboration in groups during teacher education
Collaboration is increasingly common among teachers in schools. As such, teacher education should prepare prospective teachers to effectively interact with other teachers in different types of communities or groups.

Self-interest versus group interest
People are less willing to give up an interest when in a negotiation situation than when they can do it of their own free will, as Leiden University psychologist Eric van Dijk discovered. Knowledge of this kind can be used by policy makers, for instance, to motivate people to adopt certain desirable…

Koenraad Schalm Group (String Theory and Experiment)
Truth is stranger than fiction. In 1997 Juan Maldaceña discovered a remarkable dictionary that translates equation for equation the physics of black holes in string theory into the more conventional physics of quantum mechanics of interacting particles. The remarkable possibility exists that…

The Hague International Space Resources Governance Working Group
The development of space resource activities is happening now. In the absence of a clear framework to govern these activities, there is a need to examine the concepts that are being discussed in order to ensure that they meet existing treaty obligations regarding on-orbit operations and space resource…
