This was the core question at the annual teaching conference organised by the Leiden Teachers’ Academy on 20 November. The two are not mutually exclusive, was the con…

Last year, chemists Dennis Wander and Hermen Overkleeft contributed to an important discovery about a widely used cancer drug. Their research has now been recognised as Finalist for the PNAS Cozzarelli Prize in the Biomedical Sciences class.

Marlien van Mever delved into the analysis of tiny samples, cerebrospinal fluid from transgenic mouse models for example. She validated methods that can now be used to study brain diseases such as migraine and epilepsy. Van Mever will receive her PhD on 14 June.

Andrea Bartolucci is Assistant Professor at Institute of Security and Global Affairs. In this study, the scholars adopted a multidisciplinary approach to investigate wildfire risk in Van Chan district in northern Vietnam, a region where official data are sometimes difficult to collect or inconsisten…

To what extent are there differences between countries in and outside the European Union and the Schengen area in the level of crimmigration, the merger between migration control and crime control, and to what extent can these differences be explained by the way in which state and non-state actors in…

PhD candidate Daniël Gomon has developed statistical methods that could significantly improve research in fields like medicine and demography. ‘Mathematicians don’t like unrealistic assumptions,’ he says. Gomon will defend his PhD thesis on 19 June.

What role(s) do border officials play in the enforcement and management of border control and border mobilities and how do these roles relate to the personal, organisational and larger societal context within which these officials operate?

The research master's specialisation Cognitive Neuroscience consists of five main parts: the general courses, the track-specific courses, the elective courses, a research internship and a thesis.

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?

A virtual hand that feels as if it is your own. Feeling happier because a virtual face is smiling with you. Cognitive Psychologist Ke Ma discovered using virtual reality that the way we experience our body is more flexible than we thought. Ma: ‘We can think up some fantastic applications.' PhD defence…

How do dissociative states affect the ability to suppress emotional distraction (in the context of a working memory task) in patients with Borderline Personality Disorder?

The IBL-office welcomes you and will answer all your questions regarding general information, administrative issues, or redirections towards IBL subdivisions and people.

To investigate the effectiveness of an online self-help programme for people with HIV and depressive symptoms.

Our group is part of the Metabolomics and Analytics Centre where we accompany the data from its acquisition all the way to the publication of identified associations and biomarkers for a range of human diseases. The generated data of the metabolic measurements are assessed using an in-house quality…

We strive to address the challenge of constructing a modeling language to write software which can take advantage of recent hardware developments (multicore, cloud) without compromising in its abstraction levels.

What does the daily life of those who travelled to Syria to join jihadist groups look like? Destination Syria, a new ISGA report, provides answers to this question

Netherton Syndrome (NTS) is a rare genetic skin disease caused by mutations in the serine protease inhibitor Kazal-type 5 gene, which encodes the lympho-epithelial Kazal-type-related inhibitor. NTS patients have a profound impaired skin barrier function. Because SC lipids play a crucial role in the…

Is there a sufficiently large market for drug screening and testing in Zebrafish larvae using membrane fusion?

In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…

One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…
