Imagine scanning lion dung or a mouse dropping and instantly knowing exactly what and how much the animal has eaten. Thanks to new DNA techniques, this is becoming increasingly feasible. PhD student Kevin Groen tested how effective these techniques are at unraveling the diets of wild animals.

Inaugural lecture

Lichens enthusiast Sander van Zon was eager to use his knowledge for his internship. He wrote an excellent thesis on lichens’ biodiversity in the city, of which his first scientific publication will appear soon. With it, he is nominated for the Leiden Science Young Talent Award 2022.

Metal-containing molecules combine geometrical features and a reactivity that are inherently different from that of organic molecules. My research focuses on light-activatable metal-based anticancer drugs and metal-functionalized liposomes. Light is a very selective way to activate photosensitive drugs…

In the present-day United States, to what degree(s) are far-right men and women similar and/or dissimilar in their motivating factors for engaging in far-right social movement activism?

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).

Can the pink-pigmented microbe Methylobacterium extorquens be genetically engineered to convert the sustainable raw material methanol into antibiotics?

‘It is recommended that the State assumes sovereign responsibilities to protect life, liberty and property of its citizens in the domain of cyberspace, despite the international character of cyberspace,’ says Roy van Keulen. He will defend his dissertation on digital force on Wednesday 9 May 2018.

One of the baffling aspects of international power politics is the unexpectedly major influence exercised by particular small states. Professor of International Studies and Global History Isabelle Duijvesteijn discovered that peace missions and development aid help generate power. Inaugural lecture…

In an unpredictable environment bacteria evolve the same strategy as shareholders who try to protect themselves against unpredictable swings in the stock market. Experimental evolution biologist Dr Bertus Beaumont published an article on this discovery on 5 November in the journal Nature.

Willemien den Ouden, Professor of Constitutional and Administrative Law and Academic Director of the Institute of Public Law has been appointed State Councillor at the Administrative Jurisdiction Division of the Council of State in the Netherlands.

How can zebrafish models be used to gain a better understanding of host-pathogen interaction mechanisms and to screen new drugs for infectious disease treatment?

On the basis of the characteristic aspects of a picture, certain computers can tell us what the picture is showing. They can learn this in the same way that young children are able to learn to recognize images. Further improving these techniques opens the way to a whole range of new applications. Biology…

The Biological- and Soft-Matter Physics Master specialisation is one of the two programmes Leiden offers in experimental Physics. The programme can to a high degree be tailored to individual needs and interests.

The state, and specifically the idea of nationality, is almost all-determining in social life in the Netherlands. It determines how people identify, how we interact with each other, and what (in)equality in society looks like. However, ultimately, the idea that we can divide people into different nationalities…

Hybrid zones occur where two species meet and produce offspring (hybrids). Typically, hybrids show a considerable reduction in fitness. In this thesis two hybrid zones are treated.

In 2023, many of our students and staff won great prizes and secured important research grants.

This research group, headed by Miranda van Eck, focusses on understanding the molecular mechanisms underlying cardiovascular and metabolic diseases. Cardiovascular disease constitutes a major health issue worldwide. Although significant knowledge has been obtained on the development of atherosclerotic…

This dissertation describes the history of the Ottoman county of Foçateyn as a case study of the process of transition from the Ottoman Empire to nation states.

As part of the state visit to Mexico a theme lunch on indigenous cultures was organised.

Many important topics in computer science, such as the correctness of software, the efficiency of algorithms and the modeling of complicated systems, depend on sound theoretical underpinnings. In the Theory group, we study these fundamental building blocks and develop verification methods to prove system…
