A computer can look at, and learn from, many more images than a human specialist. AI systems are rapidly becoming indispensable for medical and biological applications. But they still have to learn how to explain their decisions.

My ERC Starting Grant, funded with €1.5 million for 5 years as part of the Horizon 2020 research and innovation program, is focused on building the early warning system WARN-D to reliably forecast depression in young adults before it occurs. Why depression, and why prediction?

Although the world has made tremendous progress in health, education, sanitation and hygiene, global public health challenges still exist. Disparities in health exist between and within nations as evidenced by inequalities in disease burden, mortality, nutrition and environmental well-being. How does…

In the field of Western art music, improvisation has become a much discussed topic. In this interdisciplinary study I argue that in this context, improvisation is not to be seen as a quasi-autonomous skill or art form, but as an aspect of music-making in general.

In this research project child language phonology is studied from the perspective of a psycholinguistic speech-production model and this model is in turn studied from the perspective of developmental phonology.

An international mega-analysis on the neurobiological link between inhibited temperament and social anxiety disorder

The central theme of Rik Mom’s research group is to identify what the electrode-electrolyte interface looks like when electrocatalysis is taking place. Using specialized forms of Raman and X-ray spectroscopy, we study the chemical state and bonding environment of the electrode surface and near-surface…

It is estimated that approximately 30% of all proteins require a metal to function. Investigating the relationship between metal-binding and peptide/protein folding allows us to uncover fundamental rules for creating metallo-peptides and proteins, which in turn leads to the creation of new structures,…

Empathic or anxious mistakes? A neurocognitive investigation of the development of social performance monitoring in youth growing up in stressful versus non-stressful environments

What is the effectiveness of two school-based skills-training programs in promoting mental health?

The Faculty of Social and Behavioural Sciences brings together high-quality research and outstanding teaching.

FSW Professor Jan Dirk Blom has written a book on Alice in Wonderland syndrome. This is the first scientific book on this rare disorder, which was first described in 1955 by the British psychiatrist John Todd. Todd was inspired by the famous book by Lewis Carroll, in which Alice experiences all kinds…

The precise psychobiological mechanisms leading to chronic physiological stress responses have not been sufficiently explained, although stress is a major risk factor for disease and early death. A problem for conventional stress theory is that most of these responses seem to occur in situations without…

While acknowledging prominent legal-philosophical debates, this project proposes a radically different approach to provide insights into the concept of the rule of law.

Are traces of fire use detectable in ancient hominin genomes?

Which plant leaf characteristics are involved in thrips resistance in tomato?

Research at the THEOR group is comprised of the following research themes:

A study by a Leiden-Wageningen group shows that present-day humans are biologically poorly equipped to deal with the toxins they are regularly exposed to in smoky environments: compared to earlier hominins, we modern humans are probably even worse off. The study appeared in Molecular Biology and Evolution.…

In the field of Western art music, improvisation has become a much discussed topic. In this interdisciplinary study I argue that in this context, improvisation is not to be seen as a quasi-autonomous skill or art form, but as an aspect of music-making in general.

In the track Governance of radicalism, extremism and terrorism you will be familiarised with the academic debate regarding these contested concepts.

LIACS is a partner in the EU Erasmus+ Curriculum Development for the Asian education system. The knowledge available in the field of Data Science and Artificial Intelligence education will be shared and adapted for the Asian market.

Can a new proteomics workflow be developed to link genes and gene clusters to bioactive molecules, identify novel compounds and enhance the production in the Streptomyces lividans enzyme?

North, Middle and South America together constitute the single largest area in World Archaeology that is taught as a single focus. It is also the only major world area that saw societies develop from hunter-gatherers to early empires entirely independent from developments in Eurasia & Africa. It is,…

The archaeological heritage of South America is facing increasing threats due to the expansion of agricultural activities, infrastructure expansion, illegal wood harvesting, and the current fire emergency plaguing the Amazon and other biomes of the continent.

Methodology and Statistics focuses on the development, evaluation and application of statistical models for the analysis of psychological research data.

Within the two-year Astronomy master’s programme, you can choose from seven specialisations, ranging from fundamental or applied astronomy research in cosmology, instrumentation or data science, to combinations of astronomy research with education, management or science communication.

The project will investigate the use of Artificial Intelligence in the labour market, and how biases in hiring and promoting processes based on personal characteristics are potentially reproduced with AI-based systems.

The focus of the Bachelor Data Science & Artificial Intelligence is on computer science, and its applications in Artificial Intelligence. You will receive a strong basis in mathematics, statistics and computer science, combined with advanced knowledge of machine learning, cognitive science, human-robot…
