The aims of the project are to: further clarify 'inhibition by safety'; explore and describe all possible sagety factors, with a special focus on the primary human safety source: social connectedness; reviewing prolonged stress responses without stressors.

Research at the Catalysis and Surface Chemistry group is comprised of the following research themes:

The research within the Food research programme at CML focuses on a transition towards sustainable food production and consumption systems. We investigate from a very small to a very large scale, at a local, national or international level. We do so by researching for example molecular tools, food systems,…

How can the Safe and Sustainable by Design (SSbD) framework developed in the SSbD4CheM project facilitate the creation of safer and more sustainable chemicals and materials across various industries?

The goal of hit discovery is to identify suitable chemical starting points to modulate a drug target. A hit can be, a.o., a small molecule, a protein or mRNA. Hit identification is performed via rational design, genome mining, (targeted) library screening, or in silico approaches.

IDREEM (Increasing Industrial Resource Efficiency in European Mariculture) is a European research project launched in 2012 to protect the long-term sustainability of European aquaculture. This project has recently been featured on Euronews TV

The power of personalized nutrition lies in being able to conduct clinical research on healthy people while capturing metabolic markers sensitive to the impact of environmental and metabolic stressors (e.g. diet, changing sex hormones and the menstrual cycle).

Twenty years from now, the world population is estimated to be around 8.7 billion people, compared to the current 7.3 billion. In combination with the improvements in living standards and the corresponding growth in consumption, this will result in an enormous increase in the demand for food, consumables,…

All PhD candidates who started their project in 2019 or later take a mandatory course on academic integrity, preferably in their first year.

Overall dispersion in LCA as result of inherent uncertainties, spread and unrepresentativeness.

Can Cyanobacteria be engineered to convert the greenhouse gas carbon dioxide into the valuable chemical isoprene?

Circular economy… is it another a buzz word or a concept worth learning more about?

What are the possibilities of converting biowaste streams into value added products? What current and future technologies will enable this transition with minimal environmental and economic costs? The researchers in H2 steel project will enable the transition of sewage sludge into green hydrogen, steel…

In this thesis we examine certain phenomena in symplectic topology which are related to the theory of isolated singularities.

Statistical distributions in LCA and converting between different representations of these distributions.

The Automated Design and Analysis of Algorithms (ADA) research group pursues the development of Artificial Intelligence techniques that complement, rather than replace, human intelligence.

How can we organise society so as to keep our planet habitable for us and for all other life forms around us? To answer this question, Leiden researchers collaborate across disciplines, from biology to data science, and from environmental economy to archaeology.

In this study, we investigated the electrochemical behavior and surface evolution of Au(111) electrode under different conditions and electrochemical techniques, using a homemade electrochemical scanning tunneling microscope (EC-STM), revealing the intricate interplay between surface roughening, atom…

Damien Van Puyvelde and Paul Oling explore how government intelligence agencies can effectively collaborate with the private technology sector to meet their evolving technological needs, focusing particularly on emerging technologies such as artificial intelligence (AI) and quantum computing.

Bacteria are highly complex and diverse organisms that have adapted to survive in ecological niches ranging from the most extreme to the most heterogeneous environments.

We study cell-fate decision-making using embryonic stem cells as a model system. Stem cells integrate a large number of cues to direct their development into a great variety of cell types.

Adhyāyas 96 – 112. The Varāha Cycle and the Andhaka Cycle Continued

Welcome to StatiCS: the Statistical Consultation Service. The goal of the service is to provide statistical support to PhD candidates and other researchers.

This dissertation focused on computational methods based on first principles calculations using the Density Functional Theory (DFT) framework. Emphasis was laid on affordable methods that can provide a tradeoff between computational expense and accuracy.

The Science Council is an advisory committee to the Board of the Institute and consists of the full professors of the Institute.

Exoplanets close in to their host star receive high levels of extreme ultraviolet (EUV) irradiation, capable of heating and ultimately driving the hydrodynamic escape of their atmospheres.

The programme’s courses deal with current approaches in material culture theory, advanced methods and techniques from the exact sciences employed in artefact studies, and experimental archaeology.

Jos Schaeken has just published a book entitled 'Stemmen op berkenbast. Berichten uit middeleeuws Rusland: dagelijks leven en communicatie'.

Looking for ways to travel more sustainably once you've reached your destination? Here, we offer some ideas and helpful links to guide you in becoming a more responsible tourist. Ecotourism, defined as "responsible travel to natural areas that conserves the environment, sustains the well-being of…

The Chemical Probe Facility is part of the Leiden Early Drug Discovery & Development (LED3) center. Activity-based protein profiling (ABPP) is one of the pillars of chemical biology. ABPP determines the activity of entire protein families in living cells and tissues under physiological conditions, such…

In light of climate change, it is crucial to determine whether plant species can adapt to future climates to avoid extinction. Plants adapt to various conditions by altering their functional traits, such as leaf size or photosynthetic rate. Some traits appear linked and vary together between species,…

Twenty years from now, the world population is estimated to be around 9 billion people (now 8 billion). In combination with the improvements in living standards and the corresponding growth in consumption, this population will result in an enormous increase in the demand for food, consumables, water…

Adoptees in the Netherlands generally do not use more medication than their non-adopted peers.

Urban, Food, Water, Biodiversity, Resources and Energy: these are the main research topics of the Institute of Environmental Sciences. We always strive to be a global leader in our field. And make a real impact with both our research programmes.

To get a feeling of how we operate at LED3 when it comes to Early Drug Discovery, please browse through our case studies. When you select a case study you’ll find relevant contacts.

The first index to measure product safety, sustainability, and circularity, operationalising the EU’s (SSbD) framework.

For thousands of years, societies have fallen under the reign of a single leader, ruling as chief, king, or emperor. In this fascinating global history of medieval and early modern dynastic power, Jeroen Duindam charts the rise and fall of dynasties, the rituals of rulership, and the contested presence…

My artistic practice deals with documents and, more specifically, with the use and the exploration of their narrative potential.
