Imitation is, perhaps more than ever, constitutive of human originality.

We investigate the physics and design of mechanical metamaterial, intricately sculpted materials with properties set by their architecture.

In human cells, a meter-long DNA is condensed inside a micrometer-sized cell nucleus. Simultaneously, the genetic code must remain accessible for its replication and transcription to functional proteins.

The bacterial cell wall is a nearly universal structure that offers protection and gives the cell its shape. However, environmental stressors, such as cell wall-targeting antibiotics and hyperosmotic conditions, can induce bacteria to shift to a wall-deficient state. It is unknown whether the lack of…

My PhD thesis investigates the ecological significance of resistance against drought-induced air bubble formation inside the water conduits of plants (embolism), and the plasticity and functional aspects of stem anatomical traits in woody and herbaceous species.

Animal Sciences’ contributions to the Biodiversity & Evolution 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.

Our mission is to improve the description, prediction, understanding and the prevention and treatment of mood disorders, including unipolar and bipolar depression, as well as suicidal thoughts, feelings, and behaviors. To tackle this ambitious mission, we focus on several research streams.

Hoe kan de City Deal Kennis Maken bijdragen aan het formuleren van maatschappelijk relevant onderzoek dat de stad in al haar diversiteit centraal stelt? In de stad Leiden zijn burgers momenteel maar in beperkte mate betrokken bij het bepalen van de agenda van de lokale City Deal Kennis Maken. Dit onderzoeksproject…

The Department of Child Law and Health Law is a knowledge centre dedicated to academic research and education for both students and professionals in two fields: child law (and children's rights) and health law.

Providing each cancer patient with the right treatment remains a challenge. Oncode Accelerator aims to change this by innovating the way we develop cancer treatments, thus ensuring the patient is at the heart of the process. Leiden University, the LUMC and other partners will implement this new way…

We investigate the molecular basis underlying health and disease and provide answers to existing and emerging health problems. Within this theme, we study diseases ranging from rare genetic disorders to cancer and infectious diseases. We make use of a wide variety of model systems and pursue diverse…

The moment is there: LUGO can finally announce the winner of the Sustainability Award 2020!

NimbleAI aims at solutions for ultra-energy efficient and secure neuromorphic sensing and processing at the edge.

A liveable planet. More biodiversity. And resources which are being managed wisely. At the CML, we want to make an impact with our research and education. On this website you can read what we do to achieve that.

How can pupils and students learn to get a grip on complex 'swamp situations'? Inaugural lecture in abbreviated form held by prof.dr.ir. Fred Janssen on the acceptance of the post of professor of science education at Leiden University on 19 June 2017.

The mission of our group is understanding how science communication works to improve the interaction between science and society. We believe better science communication can improve our society and engage many different groups with science, also improving science.

The moment is there: LUGO can finally announce the winner of the Sustainability Award 2020!

A place where scientists and students from Leiden University and residents of The Hague come together to create innovative solutions for sustainable living in the city: that's what the Sustainable City Lab aims to be. When we talk about "sustainable living" we think of many different things. For example:…

The LUGO team is part of the Administration and Central Services department of the university, with it falling under the Strategy and Academic Affairs department. Naturally, it falls into the sustainability team of the University, which consists of two full-time employees alongside the LUGO Team. The…

To get an idea of the science communication products and research that is possible, a few examples of student projects of recent years are shown below.

The project seeks to develop an eco-design framework for single-use medical devices and packaging

The endophytic microbiota is a community of various microorganisms that reside in plant tissue. These microbes are known to promote plant health and resilience, and their members do not simply exist side by side.

De decentralisaties van de zorg aan langdurig zieken en ouderen, jeugdzorg, en werk en inkomen die vanaf 2015 zijn doorgevoerd in Nederland hebben geleid tot een transitie van een centraal naar een lokaal stelsel van zorg en welzijn. Deze transitie beoogt zorg en ondersteuning dichter bij de inwoners…
