The first Eugene Garfield Award for Innovation In Citation Analysis has been granted to Jian Wang, Assistant Professor in the Science Based Business Program at Leiden University.

This thesis explores Breaking of Ensemble Equivalence (BEE) in random graph models by examining the spectral properties of adjacency matrices. The goal is to identify spectral characteristics that differentiate random graph ensembles, enhancing the understanding of complex network structures and beh…

On Sustainable Tuesday, two weeks before Dutch Budget Day, the Dutch cabinet receives a suitcase full of sustainable ideas and initiatives. The initiators' aim: to make the government plans for the upcoming year a little more sustainable. At the Leiden Institute of Environmental Sciences (CML), assistant…

Plants and their pollinators form complex interaction networks. Within these networks, species differ widely in the number of species they interact with.

We found that, next to the effectiveness of the intervention, it’s also very likely that the intervention is cost-effective compared to attention only.

How to stimulate novel research in science and innovation

The information below concerns courses that our group teaches in Leiden. 

Research in the POD-group addresses all features of random phenomena – modelling, structuring, analysis, control, optimisation – and covers both fundamental and applied aspects.

In meta-analysis, heterogeneity often exists between studies. In such cases, it is essential to investigate the sources of heterogeneity and understand the relationship between effect size and study characteristics (i.e., moderators).

Effectiveness of an early intervention program for anxiety-prone toddlers in the Netherlands

The Social Assistance and Minimum Income Levels and Replacement Rates Dataset, assembled by Jinxian Wang and Olaf van Vliet (version December 2016), provides data on minimum income benefit schemes in 33 countries from 1990 until 2009.

LCN2 hosts seminars on the last Friday of each month.

China is a one-party regime, yet elections are held for the local congresses. PhD candidate Wang Zhongyuan investigated how the Communist Party uses this democratic instrument to strengthen the authoritarian regime. PhD defence 31 January.

If you are interested in studying stochastics, the following information will help you to choose the right path.

What is the effectiveness of (booklet or online) self-help programmes for people with somatic stressors and depressive symptoms? What works best for whom? How to improve motivation and adherence?

Master projects are available in

This thesis provides explicit expressions for the density functions of absolutely continuous invariant measures for general families of interval maps, that include random maps and infinite measure transformations, not necessarily number systems.

How to facilitate the translation of science into innovation

The research programme Probability Theory focuses on probability theory and on operations research.

New and reemerging infectious diseases call for innovative and efficient control strategies of which fast vaccine design and development represent an important element.

Leiden Budget Incidence Fiscal Redistribution Database (2011), assembled by Chen Wang and Koen Caminada (Version 1, August 2011), presents the disentanglement of income inequality and the redistributive effect of social transfers and taxes in 36 LIS countries for the period 1970-2006.

Leiden LIS Budget Incidence Fiscal Redistribution Dataset on Income Inequality (2017), assembled by Jinxian Wang and Koen Caminada (Version 1, November 2017), presents the disentanglement of income inequality and the redistributive effect of social transfers and income taxes in 47 LIS countries for…

Leiden LIS Budget Incidence Fiscal Redistribution Dataset on Relative Income Poverty Rates (2019), assembled by Koen Caminada and Jinxian Wang (Version 1, February 2019), presents the disentanglement of relative income poverty measurers and the anti-poverty effects of social transfers and income taxes…

Welcome to the Graduate School of the Faculty of Humanities.

How do we process language and speech? How do we integrate information at different levels – intonation, sentence structure, meaning, tone, words, sounds - and how does information at one level interact with information at another level?

Dynamical systems describe the evolution of objects in a space over time and may be used to model physical phenomena. Due to this, much research is dedicated to understanding the mathematics of dynamical systems.

The Leiden LIS Sectoral Income Inequality Dataset, assembled by Chen Wang, Stefan Thewissen and Olaf van Vliet (Version 1.1, March 2014), contains information on multiple indicators of earnings inequality and employment within 9 sectors and 12 subsectors, drawing upon micro data from Luxembourg Income…

We study the dynamics of individual emitters in micro cavities.

While colloidal aggregates are often undesirable due to their random shapes, we exploit them as a starting point to synthesize patchy particles.

In what way can teachers support and enlarge student engagement in a blended learning context?

Our group explores the larger domain of quantum measurement. In particular we investigate two themes that are closely connected: The detection of specially prepared quantum states of light and understanding and characterizing quantum photon detectors.

This dissertation investigates the propagation of solitary waves in the presence of random disturbances.
