Synthetic cells, also known as artificial cells or protocells, have wide ranging applications from drug delivery vectors to cell models. In biotechnology they can function as micro- or nanoreactors with possible applications in biocatalysis and photocatalysis. Phospholipids are by far the most commonly…

Does a moving hybrid zone leave a genomic footprint?

Hybrid Intelligence (HI) is the combination of human and machine intelligence, expanding human intellect instead of replacing it. HI takes human expertise and intentionality into account when making meaningful decisions and perform appropriate actions, together with ethical, legal and societal values.…

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.

This dissertation explores how Large Language Models (LLMs) can effectively and responsibly contribute to complex decision-making processes. By combining AI and human intelligence, Hybrid Intelligence (HI) emerges, allowing the strengths of both humans and machines to be utilized.

A comparative analysis of legitimation strategies in tree hybrid regimes: Russia, Venezuela, and Seychelles.

There are about 35,000 students with chronic illnesses in the Netherlands. If they cannot receive education in the classroom, they may be able to do so from home or a hospital with hybrid education. The question in this study is: how can interaction with the teacher and fellow students be promoted?

A Josephson junction is a device where a thin insulating barrier or a nanostructure is placed between two superconducting leads. Such a junction is essential to superconducting qubits that store quantum information due to its anharmonic spectrum.

This project involves research into the oeuvre of the Sundanese sculptor Iko, who has worked for the Catholic mission in Java and has carved sculptures for a chapel and church in Ganjuran. The images were designed by the Catholic layman Jos Schmutzer and are characterized by a fusion in style and symbolism…

Metal complexes and 2D materials like graphene were combined to produce structures that can function as sensors.

On 2 April 2025, Anna Marhold, a member of the Peace and Security Committee of the AIV and Assistant Professor at the Grotius Centre for International Legal Studies, joined a technical briefing to parliament providing advice on hybrid threats and societal resilience.

Our annual "Science to Experience" exhibition of student works is hosted by the V2_ Lab for the Unstable Media. This year's theme is "HYBRID".

Since September, a large part of education is 'hybrid': students can attend courses both at home (online) and in person in lecture halls. How do students themselves feel about this? We asked Emma and Cornelia of the Research Master Classics and Ancient Civilizations.

Direct radiocarbon dating of human remains is crucial for the accurate interpretation of prehistory. Yet given the scarcity of prehistoric human remains, direct dating is often too destructive for important fossils. The reduction of sample size necessary for dating bone is therefore of great interest…

Ben Wielstra studies hybrid zones, regions in which distinct populations of organisms meet, mate and produce genetically admixed offspring. In the journal Current Biology, he introduces hybrid zones in an accessible way.

From 16 to 19 September 2021 a hybrid conference will take place on animation in the Middle Ages. This conference is a cooperation between the University of Bergen (Norway) and the A. Zelwerowicz National Academy of Dramatic Art in Warsaw, Branch Campus in Bialystok (Poland).

For present purposes, it is important to distinguish between an early period of settlement, about 6800-6200 BC, and a late period, about 6200-5800 BC, at Tell Sabi Abyad.

This thesis pioneers diatom molecular identification and quantification through genome-scale methods, with four key aims: (i) reviewing DNA/RNA sequencing methods in aquatic biomonitoring to highlight their strengths and limitations;

Triplet superconductivity refers to a condensate of equal-spin Cooper pairs (pairs of electrons with equal spin).

Tuberculosis is a major global health problem caused by the Mycobacterium tuberculosis complex, claiming more than a million lives annually.

The Western Mediterranean is a key region to understand human dispersal events within and out of the African continent as well as for the eventual replacement of Neanderthals by anatomically modern humans during the Pleistocene. Central to any conclusive interpretation of archaeological and palaeoclimatic…

Synthetic or artificial cells are vesicles, often lipid vesicles, with wide ranging applications from drug delivery to nanoreactors in biocatalysis. We are developing polymer-lipid hybrid vesicles for applications in compartmentalised biocatalysis, in which the polymer has been shown to greatly enhance…

How does invasive hybridization affect threatened native species?

Research in the Lars Jeuken group focusses on redox-active proteins and membranes enzymes, aiming to understand bacterial respiration at the molecular level for the development of antimicrobials and semi-artificial photo-synthetic cells.

Polymyxins are clinically used antibiotics, discovered in mid-20th century. Once abandoned due to excessive nephrotoxicity, they are now used increasingly to address infections caused by multi-drug resistant Gram-negative bacteria.In this thesis, we describe the development and synthesis of analogues…

A sustainable resource management is an essential aspect to satisfy the current human needs without compromising the needs of future generations.

We use DNA strands to stabilize few-atom silver clusters, which show unique optical and chemical properties. This thesis involves the study of these constructs for various applications.

Blended and hybrid teaching are presented as crucial in promoting teaching innovation, as well as more flexible study approaches allowing students to develop their own tailor-made study programmes. While the strategy document focuses on the positive aspects of digital teaching tools, no systematic study…

Why do opposites attract? According to Karin van der Tuin, researcher at Leiden University Medical Center (LUMC), it could be because of your DNA. The more you differ from one another, the better. She will be testing her ideas at the Lowlands festival Lowlands, where she will subject visitors to DNA…
