Intelligence of the crowd, or in other words, intelligence of a large, random collective, exists mostly in social media platforms such as twitter. The collective does not comprise (at least not necessarily) experts on crises, just regular people mostly. Nevertheless, there is valuable intelligence to…

Our research deals with the deep history of Europe and Eurasia, from the inception of farming up until the beginning of the Roman Period. This was a period in which key developments took place that had a profound impact on European landscapes and society until the present day. Our research and teaching…

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

The Copenhagen interpretation of quantum mechanics states that a measurement collapses a wavefunction onto an eigenstate of the corresponding measurement operator.

Detecting planets during their formation stages is crucial for understanding the history and diversity of fully developed planetary systems like our own. However, observing young planets directly is challenging because they are often deeply embedded within their host protoplanetary discs, rich in gas…

This book contextualizes the use of terror as part of wider movements of political contention, demonstrating that terroristic innovation occurs as part of wider historical processes rather than in a vacuum.

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…

The Human Origins group at Leiden University studies the archaeology of hunter-gatherers, from the earliest stone tools in East Africa, more than three million years old, to the origin of sedentary societies towards the end of the last ice age.

On the 27th of June, Timothy Mac Hadjah successfully defended a doctoral thesis. Leiden University Centre for Linguistics congratulates Timothy on this achievement!

The Astronomy and Data Science master’s specialisation at Leiden University combines advanced Astronomy courses with relevant courses from the Computer Science programme at Leiden University.

We are cosmologists, in other words we use physics to study the Universe, how it started and evolved into the structure that we observe around us.

Research at Leiden Observatory spans the full width of modern astrophysical enquiry. It is based on observation, theory, simulation, and experiment. Two broad clusters characterize the ongoing research. Within each theme, researchers carry out their personal and specialized research programme. The two…

Three projects with Leiden researchers are to receive a subsidy from NWO for the construction or renovation of large-scale research facilities. They will be working on electron microscopy, an X-omics initiative and an X-ray telescope. The projects are part of the National Roadmap for Large-Scale Scientific…

Every year, around 400 PhD candidates defend their dissertation at Leiden University, spread across all the University’s different disciplines.

This project aims to further understand the molecular details related to the biosynthesis and function of Galf containing glycoconjugates in fungal Aspergillus spp.

Description of The Regional Network on the Synergy between the Convention on Biological Diversity and the UN Convention to Combat Desertification.

Postdocs, or early career researchers, play a crucial role at Leiden University. They make a major contribution to our research. In 2019, Leiden University employed around 400 postdocs across our faculties in Leiden and The Hague, LUMC not included.

Harriet Hunter defended her thesis on 26 September 2018.

This dissertation focuses on a new field of artistic research in which a visual artist takes on the role of researcher. The main research question is whether performance art integrated in an ecumenical service, combined with artistic directions from the artist, can enhance the religious experience of…

Upon receiving their diploma from LUC, our students spread their wings to pursue prestigious master’s degrees, PhD studies or to start their professional careers. Due to the many academic fields that are taught at LUC, the options for their future are vast and diverse. It is unsurprising that LUC’s…

Leiden archaeologists have identified a number of bone fragments that were excavated in Germany two years ago. The fragments are from a sabre-toothed cat and appear to be parts of the skull of a prehistoric feline that is over 300,000 years old.

Even embryos can become embroiled in an evolutionary arms race with another species. Leiden biologists demonstrate this with larvae of the rosy bitterling that parasitize the gills of freshwater mussels. They published their research on February 19 in PNAS.

The annual commemoration of the nation’s war dead on Dam Square and at Waalsdorpervlakte, the Dutch apologies for historical slavery and the Cleveringa Lecture itself: our relationship with history is often ritualistic, Cleveringa Professor Frank van Vree will say in his inaugural lecture on 27 Nove…

In the large gas clouds between the stars, chemical reactions take place under extreme conditions, giving rise to both small molecules, such as water and common salt, as well as large complex molecules that can serve as the building blocks of life. This is known as astrochemistry and it is something…

The aim of the research project is to get insight in the biostratigraphical age and the palaeoecological setting of the Schöningen sites and hominin behavior and subsistence during the late Lower Palaeolithic.

Research at the Macromolecular Biochemistry group is comprised of the following research themes:

Bones contain information about people’s lives such as where they came from, their age at death and which diseases they suffered from. Researchers can deduce a lot from them about a person’s life and about human evolution. This generates leads that could help solve present-day problems, such as how…
