A full overview of BPOC/SSNMR PhD theses.

In Leiden University's Vision on Sustainability 2030, biodiversity (biological diversity) is an important focus in its teaching and research and on its campuses.

How can we manipulate the biotic and abiotic environment to increase thrips resistance in tomato and chrysanthemum? More specifically we ask: How can plant secondary metabolites that are not soluble in water be delivered to plants in seed coating or root dipping treatment? Can bacteria be used to…

Animal Sciences’ contributions to the Evolution & Biodiversity research theme include evo-devo research, the evolution of cognitive and behavioural traits, and the evolutionary mechanisms of stress adaptation. This research involves both indoor and outdoor studies.

Decentralized plug and play systems for energy production are the future picture of our society. Artificial photosynthetic systems are used for this purpose.

Barrier function is the natural role of the skin. The lipid matrix present in the outermost layer of the skin, the stratum corneum is important for this function.

As a contribution to the changing legislation and evolving societal attitudes concerning environmental issues, this project aims to enhance and manipulate the plants’ own natural defense mechanisms against western flower thrips (WFT).

LUCIS promotes high-quality research on Islam and Muslim societies and actively communicates the insights and findings of that research to the larger public.

This thesis systematically studies the physicochemical properties of non-planar, propeller-shaped, polycyclic aromatic hydrocarbons. The synthesis of several so-called propellerenes is described on a gram scale, using optimized procedures aimed at using less hazardous reagents and reducing the amount…

This study focuses on the local level impacts of a highly globalised industry: the international trade in tropical timber.

Making public space more sustainable is considered very important in this project. The Humanities Campus will become a pleasant place to spend time, with lots of greenery. Here, people can relax and find coolness on hot summer days.

Can we use indigenous microbial rice communities to reduce methane production in agricultural settings?

Soil is a home for an unbelievable diversity and abundance of microbial life that is essential for supporting life on our planet.

The Great Rift Valley in Africa is a real treasure trove for discovering early human fossils. The fossils found in this part of Africa have determined our view of human evolution. But was the Great Rift Valley really the place where evolution took place or just a place where fossils are well preserved…

In the Schouwburgstraat, LUGO is currently redesigning the back-garden in order to increase biodiversity and make it a more beautiful space. Throughout October 2023 until March 2024, we will be making changes to the garden with our team of volunteers.

In the research programme Drug Discovery & Safety, we are interested in the efficacy and safety of new drugs and novel means to decipher these aspects. Hence, we employ advanced imaging and high-throughput screening techniques next to computational approaches such as chem- and bioinformatics.

Everyone knows smoking is unhealthy, but did you also know that smoking is not good for the environment? In parternship with UFB, we are organising a number of action days to pick up cigarette butts, hand out sustainable ashtrays and inform people about how they can smoke more sustainably!

In recent decades, climate change has led to more frequent and severe drought events, causing serious consequences such as increased forest mortality and significant crop yield losses. Understanding how drought affects plants, especially economically important herbaceous species, is crucial for predicting…

Metal-based prodrugs based on ruthenium(II) polypyridyl complexes have proven to be very suitable for application in both photodynamic therapy (PDT) and photo-activated chemotherapy (PACT).

Freshwater is an important resource, but at a great risk of species decline due to habitat loss, pollution and over-exploitation, and invasive alien species.

How to stimulate novel research in science and innovation

Cardiovascular diseases are the primary cause of death in the world with atherosclerosis as primary underlying cause.

The barrier function of the skin is primarily provided by the stratum corneum (SC), the outermost layer of the skin. Skin barrier impairment is thought to be a primary factor in the pathogenesis of atopic eczema (AE).

OBJECTIVES: To determine whether the lipid/protein ratio and the total dry SC mass per surface area are related with the skin barrier function of controls and AE patients.

Creating information portals for support of European environmental policy.

Artificial photosynthesis aims to produce fuels from solar energy using chemical processes. In semi-artificial photosynthesis, a hybrid approach is taken using both chemical and biotechnology approaches. We aim to develop hybrid systems between light-harvesting nanoparticles and redox-enzymes (oxidoreductases)…

Politics, Culture and National Identities investigates a wide range of national political cultures in Europe and the Americas in the 19th and 20th centuries.

Inspiring and relaxed – these are qualities that describe the Netherlands perfectly. At the same time, there is much more to say about the country. For instance, according to the 2018 UN Human Development Index, the Netherlands is ranked tenth among the best countries to live in.

On 28 February, Professor E.W. Meijer, member of Leiden University’s Board of Governors, was appointed Commander in the Order of the Dutch Lion.

Bright explosions appear all over the radio and gravitational-wave sky. This dynamic side of the universe which has just been discovered, can be mapped by self-learning machines. The National Science Agenda granted 5 million euro’s to CORTEX, the Center for Optimal, Real-Time Machine Studies of the…

An overview of awards and prizes granted to our staff and students in 2017, as well as special appointments and royal distinctions.

JUSTREMIT is an ERC-funded project that brings together political theory, ethnography, and security studies in an interdisciplinary study of remittances and global justice.

Following the Beirut explosion, BBC's podcast series The Foodchain explores the chemical that caused the blast: ammonium nitrate. A compound that is widely used to produce fertilizer. Professor of Environmental sustaibability Jan Willem Erisman tells about the effects of nitrogen on the environment.

The sustainable production of hydrogen could potentially be made more efficient by adding a cleverly chosen salt to the process. Researchers at the Leiden Institute of Chemistry (LIC), in collaboration with physicists at the University of Twente, have discovered that the type of salt present in the…

Leiden University's International Honours College, Leiden University College The Hague (LUC) experienced empty halls and empty classrooms this past year on the residential campus on the Anna van Buerenplein in The Hague due to the global pandemic. Dr Paul Hudson designed a Covid-proof course that enabled…

What is Leiden University doing to make its buildings future-proof and independent of fossil energy?

Inaugural lecture

Leiden archaeologists investigate how people in the past impacted their environment. Together with scientists, environmental scientists, and humanities experts, they use this information to draw conclusions about the present – and show what we can learn from it for the future.

If a society is to be secure, sustainable and resilient, conflicting interests must be reconciled. Researchers at Leiden University study the behaviour of individuals, groups and states in relation to this issue, and use their knowledge to promote equality within and between communities.
