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…

ADHD & ME aims to explore how enhancing self-esteem can break the relation between ADHD symptoms and comorbid disorders, such as anxiety and depression. In this study we assess the effectiveness of a Cognitive Behavioural Therapy (CBT) program called Competitive Memory Training (COMET) for improving…

The project falls in the context of the EU Thematic Strategy on the Sustainable Use of Natural Resources (COM(2005)670). The Institute for Environment and Resources (IES) of the Joint Research Centre (JRC) has developed three sets of decoupling indicators. Such indicators require the definition of a…

Using biomethane to produce ammonia, a crucial chemical in agriculture, could drastically reduce the climate impact of the process. In a study published in One Earth, researcher Robert Istrate shows it’s even possible to make ammonia production net-zero or carbon negative.

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

Analytical tools for environmental design and management in a systems perspective. The combined use of analytical tools.

Inaugural lecture

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.

From filtering UV light in sun cream to preventing perspiration odour in socks and sterilising fridges and washing machines. The use of nanoparticles in products is increasing. But what is the impact of these miniscule particles on the environment?

BioSolar Cells is a five-year research project in which ten knowledge institutions and 45 private industries work together.

Comparing the global warming potential (GWP) of the service provided by an iRex Digital Reader to the same service provided by an office printer using a scanning LCA.

What would be the environmental performance of the Carbon4PUR technology at industrial scale in the future?

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

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.

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

Political scientist Luzia Helfer (Leiden University) empirically tested claims about media-politics relatiopns using unique data from experimental studies with elected politicians and political journalists in Switzerland and the Netherlands.

Life cycle assessment (LCA) reveals the total environmental impact of products or production processes, and EU rules are going to make this even more important.

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 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.

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?

We aim to provide new insights relating to the spectacular multi-cellular life cycle of streptomycetes and other actinobacteria.

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…

A faculty like ours is a treasure chest of and for languages, culture, and society. In the coming year, we will be making sure these treasures get extra attention, both internally and externally, during Leiden University’s 444th anniversary.

How do you make a technology sustainable that does not even exist yet? Well, by bringing together an interdisciplinary team of pioneering European experts right at the start and paying attention to sustainability right from the development phase.

Evaluating the environmental consequences of diet changes in the European Union.

Bacteriophages, or phages for short, are the most abundant biological entity in nature. They shape bacterial communities and are a major driving force in bacterial evolution.

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.

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.

Migration imposes special pressures on the meaning, experience and organization of lifecycle rituals. These pressures are felt most strongly by Muslim migrants to Western Europe. In this innovative study, Nathal M. Dessing examines the effects of migration on the life cycle rituals of Moroccan, Turkish…

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.
