This thesis describes the development and validation of new high-contrast imaging techniques, with the ultimate goal of enabling the next generation of instruments for ELT-class telescopes to directly image Earth-like extra-solar planets orbiting around nearby stars.

In design optimization problems, engineers typically handcraft design representations based on personal expertise, which leaves a fingerprint of the user experience in the optimization data. Thus, learning this notion of experience as transferrable design features has potential to improve the performance…

Astronomers want to understand the Universe, from the Big Bang to the present day, and what the future will hold. In Leiden they focus on two key questions: ‘How did stars and planets originate’ and ‘How were galaxies and black holes formed in the young Universe?’ A new generation of telescopes – just…

If we want to build robots and computer systems that are not only smarter but also possess more social skills, we first need to find out more about how humans interpret information. Max van Duijn and Tessa Verhoef conduct research at the intersection of cognitive science and AI.

The dissociative chemisorption of a molecule on a transition metal surface represents a rate-limiting step in many heterogeneously catalyzed processes, whereby most chemicals are made. In spite of the importance of this reaction, an accurate first principles approach to modeling it does not yet exist.…

We review the state-of-the-art in the theory of dissociative chemisorption (DC) of small gas phase molecules on metal surfaces, which is important to modeling heterogeneous catalysis for practical reasons, and for achieving an understanding of the wealth of experimental information that exists for this…

Within the two-year Astronomy master’s programme, you can choose from seven specialisations, ranging from fundamental or applied astronomy research in cosmology, instrumentation or data science, to combinations of astronomy research with education, management or science communication.

This study aims to provide a long time perspective of human landscape manipulation. Studying the roles of prehistoric foragers in past ecosystems is of great importance to establish the character of past 'natural' landscapes and to enhance the management of current ones.

What is it like to be old? Many young people cannot really imagine what it is like. For a group of Honours students, however, this question has been answered. They had the chance to wear an age simulation suit during the Bachelor Honours Class ‘Vitality and Ageing’.

Joost Beltman (LACDR, Leiden University) has provided novel insights in the way T cells migrate towards virus-infected cells. This was accomplished by a combination of experimental research in the group of Ton Schumacher (Dutch Cancer Institute, NKI) and computer simulations in collaboration with Rob…

Five promising researchers at Leiden's Faculty of Science have received a Veni award from NWO. They can use the award - of up to 250,000 euros - to carry out research over a three-year period. Of the total of seventeen Leiden Venis, four went to Leiden Observatory and one to Institute for Biology Le…

A night sky of more than 40 petabytes in size, simulating young star clusters and understanding how the body inhibits viruses: three Leiden projects have received computing time on one of the national computer systems.

Leiden students organised a Model United Nations (MUN) from 3 to 6 May in The Hague. An MUN simulates the working of the United Nations and is intended to allow students to learn about the practice of international relations. View the photo series.

For their honours internship, second year students of the Honours College 'Governance & Global Affairs' created the serious game Fallen Angels. In the game you take on the role of NATO, and have to deal with a crisis. Last month, a new generation of Honours students had the opportunity to be the first…

The standard approach to build a quantum computer with Majoranas as building blocks is to convert them into qubits. However, a promising application of quantum computing—quantum chemistry—would require these qubits to be converted again into so-called fermions. Physicists from Leiden and Delft suggest…

Sonja Boas developed new techniques to study vascular growth computationally. The results of her research provide a better understanding into mechanisms behind vascular growth, which is relevant to the development of medical therapies. She defends her thesis 'Computational modeling of angiogenesis'…

The worldwide race to the quantum computer is in full swing. This computer can take on computing tasks that we can only dream of today, such as finding proteins that can be used as medicines in seconds flat.
