Every PhD candidate has access to MS Teams ‘LACDR PhD group’. This site is specially for PhD candidates of LACDR. We strive to collect here all relevant PhD information and to stimulate the collaboration and communication in the LACDR PhD community.

Leiden University has a rich history in the domain of Papyrology. Papyrology+, founded in 2014, is a collaboration of Leiden scholars studying (Abnormal) Hieratic, Demotic, Aramaic, Greek, Latin, Coptic, and Arabic papyri from a socio-historical, economic and linguistic perspective.

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…

We examine the effect of social learning on emotional competence in children and adolescents with a typical or atypical development.

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.

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 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.

The main topic of this PhD thesis is the Arakelov ray class group of a number field, an algebraic object that contains both the ideal class group structure and the unit group structure.

Terrorist groups adapt to environmental changes to maintain power. This project provides new insights by developing a theory of strategic target selection and using big data analytics and machine learning to test these hypotheses.

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…

On 23 April, Rowie Stolk defended the thesis 'Interest group litigation in the Dutch polder: An interdisciplinary perspective on access to the courts'. The doctoral research was supervised by Ymre Schuurmans and Jerfi Uzman.

This dissertation is a collection of four research articles devoted to the study of Kummer theory for commutative algebraic groups.

The programme group Clinical Neurodevelopment Sciences is located in the Faculty of Social and Behavioural Sciences of Leiden University near Central Station.

The programme group Educational Sciences is located in the Faculty of Social and Behavioural Sciences of Leiden University near Central Station.

The focus of our theoretical physics research is the nature of macroscopic matter that is in one or the other way still in the grip of quantum physics.

Our research primarily focuses on the early universe and its origins in theories that go beyond the Standard Model of particle physics.

The research group ‘Quantum and Society’ explores the boundary between quantum technology and science communication.

On 7 and 8 October 2016 Leiden Law School received a visit from the external review committee, led by Mr Fred Hammerstein. This review committee reports on the results of research performed at the faculty and provides advice on how these results can be improved in the future. The assessment of the research…

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…

My work is motivated by the necessity to extend Standard Model of Particle Physics in order to explain three observed phenomena that this great theory fails to accommodate

This minor focuses on how our thoughts, emotions and behaviour are influenced by other people, and how we influence other people.

We are cosmologists, in other words we use physics to study the Universe, how it started and evolved into the structure that we observe around us.

Health inequities, obesity among children, loneliness, performance stress among youngsters. What are the drivers behind such ‘wicked problems’ and how might they be related? This interdisciplinary minor offers you the possibility to work with societal partners to gain a deeper understanding of real-life…

The Leiden Political Economy Group (L-PEG) is a multi-disciplinary network of scholars with a research interest in (comparative / global) political economy based at Leiden University. Our members belong to various institutes and faculties across Leiden University, and from other universities across…

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…

Enforcement of group cooperation fails because of discriminatory punishment, according to research by Welmer Molenmaker and colleagues. When group members have different backgrounds, punishment turns into a double-edged sword: no longer used just to prevent group exploitation, but also to break the…

The thesis focuses on synthesis strategies in oligosaccharide campaigns, and the influence of protecting groups.

The Educational Sciences programme group of the Institute of Education and Child Studies at Leiden University provides courses in the field of student education and the learning and development of children in the school context.

The focus of our theoretical research is understanding the behaviour of soft condensed matter, physical matter which is deformed or structurally altered by thermal fluctuations or small stresses.

The programme group Research Methods and Statistics offers support to researchers from a variety of research projects within Education and Child Studies.

We explore the particle physics and quantum world at the time of the big bang.

Interest groups play an important role in democratic society.

The program group Forensic Family and Youth Care Studies is located in the Faculty of Social and Behavioural Sciences of Leiden University near Central Station.

The program group Learning and Behavior Problems in Education is located in the Faculty of Social and Behavioural Sciences of Leiden University near Central Station.

This book offers novel perspectives on the national and international dimensions of the post-war welfare state in Western Europe and North America.

The group Theoretical Physics of Life Processes, led by Helmut Schiessel, focuses on the physics of chromatin, the DNA-protein complex that fills the nuclei of eukaryotic cells.
