The major aim is to examine the potential of learning the body to produce a similar physiological (autonomic, neuroendocrine, or immune) and physical (e.g., desensitization of persistent physical symptoms) response to placebo medication than to active medication (pharmacological conditioning). If proven…

Our research at CWTS is organized in three focal areas. These focal areas represent our core areas of interest, as defined in our knowledge agenda for the period 2023-2028.

In theory, the responsible conduct of research leads to greater trust in scientific findings, fosters a healthy academic culture in which scientists can flourish, and promotes a productive and mutually beneficial relationship between science and society. In practice, this is achieved by improving transparency…

Our everyday life consists of all sorts of spatial processes: we find our way to work, remember where we left our keys, and are able to pick up our cup of coffee. We study how the human brain processes such spatial processes. From a clinical perspective, we are interested in how acquired brain damage…

To make the right clinical decisions or develop effective diagnostic tests and treatments, it is important to understand the underlying mechanisms of a condition or behavior.

The main focus of our research programme is on adolescence, a key transitional period in human development. The programme puts emphasis on combined experimental behavioural and neural analysis of normative transitions and deviations in adolescent development.

When and how does social anxiety develop? How can it go astray in some adolescents? How can we help troubled young people to attend school regularly and return to a normal developmental pathway?

Recent years have seen a vibrant scholarship on health policy and politics. While much is now known about changes to health policies and institutions over time, this study finds that scholarship still lacks research on the linkages between health policies and health outcomes (Marmor & Wendt, 2012).…

Is EEG theta\beta ratio predictive towards the negative effects of stress on cognitive performance in individuals suffering from performance anxiety? Can we improve resilience to performance anxiety by using a theta\beta ratio neurofeedback intervention?

The aim of this project is to explore the use of statistical interaction models to quantify cross-omics and omics-drug interactions in large-scale clinical and experimental datasets

Atopic dermatitis (AD) is a common inflammatory skin disorder characterised by various epidermal alterations. Filaggrin (FLG) mutations are a major predisposing factor for AD and much research has been focused on the FLG protein.

Sip2021 is sponsored by the Dutch Research Council (NWO) and the Graduate School Experimental Plant Sciences (EPS).

The company Azafaros was established in 2018 to translate innovative science from Leiden University and Amsterdam University Medical Center into novel disease-modifying treatment modalities for rare genetic metabolic disorders such as lysosomal storage diseases.

Growth hormone profiles are pulsatile and highly variable between individuals, limiting the implementation of mathemathical models to quantify an individual's secretion.

On 29 June 2017, Doris Dull-Zessner defended her PhD dissertation “Value Congruence in a Multinational Corporation”. The supervisors are Professor J.A.A. Adriaanse and Professor J.I. van der Rest.

TRIXY is a national Center of Expertise, in which clinical professionals and expert researchers work together to improve knowledge and clinical care for children with X and Y chromosome trisomies.

The transition period in which men become fathers might provide an important window of opportunity for parenting interventions that may produce long-term positive effects on paternal care and, consequently, child development. Existing prenatal programs traditionally focus on maternal and infant health…

Research into the evolutionary backgrounds of our diets can help us make the right choices in diet, health and lifestyle.

Internationalisation is an important part of the mission and vision of Leiden University. The Erasmus+ programme, an initiative of the European Commission, makes a substantial contribution to this goal. Erasmus+ provides grants for educational projects with partners within and outside Europe, and facilitates…

On this page, you will find the recordings of the online This Week's Discoveries from May 12, 2020, as well as a list of speakers since October 2015.

The major aim is to develop, evaluate, and implement disease-generic cognitive-behavioral interventions through the internet in order to optimize tailored health care for patients with chronic somatic conditions.

Issues such as climate change, the depletion of natural resources or social inequality are too complex to be addressed from a single scientific discipline or by a single country. Leiden University has the expertise to bring the resolution of these enormous problems a small step closer.

After an introductory first year, in the second year you will learn more about the four themes: the sustainable city, the safe city, the multicultural city and the healthy city. In years two and three you will have elective options, including a minor, studying abroad and an internship.

We produce more data than ever before, and researchers gather more and more information. That data contains a wealth of insights and new possibilities. But how do you extract them? In Leiden, statistics and information science come together in innovative multidisciplinary research. Read more in the…

Professor Felix Ameka and university lecturer Maria del Carmen Parafita Couta have received an NWO Open Competition grant together with Enoch Aboh (University of Amsterdam) to do research on ‘code-switching’: switching languages by multilinguals.

Scientists widely agree that we must limit global warming to 1.5 degrees Celsius to avoid catastrophic climate impacts. Environmental scientist Laura Scherer investigates how we should change lifestyles to achieve this temperature goal. Her research is part of the 4.8-million-euro Horizon 2020 project…

The combination of data science and sports is a hot topic. In a talk during the opening of the Academic Year at the Faculty of Science, Professor Joost Kok explained what data analytics can teach us about sports.

EuroScience Open Forum – ESOF - is Europe’s biggest multidisciplinary and prestigious scientific conference. ESOF2022 will take place from 13-16 July 2022 and is hosted by Leiden as the European City of Science (in the Netherlands). The Kamerlingh Onnes Building is one of the locations of the ESOF and…

The financial sector, supply chains and ecology. Not necessarily topics you might associate with physics, yet it’s exactly what new professor Diego Garlaschelli is dealing with. The common thread? Complex networks.

Simulation project EAGLE has won the 2022 Group Achievement Award of the Royal Astronomical Society. EAGLE is a large collection of simulations about the formation of galaxies. The largest simulation contains as many as 6.8 billion particles and took months to calculate on the world's fastest superc…

Having a chronic somatic condition can result in a variety of impairments in patients’ daily lives, including not only physical complaints such as pain, itch, and fatigue, but also problems of negative mood and impairments in social relationships. Next to disease characteristics, individual difference…

Leiden University social scientists have shown that customised intervention pays off. A new fundamental research-based approach in children who are in danger of going off the rails has delivered spectacular results.

Both good employer practices and good employee practices are open norms. These open norms can lead to uncertainty about what employers should focus on and what rights (and obligations) employees have in that respect. The objective of this study is to give substance to the norm of good employment practices…
