Laboratory, observation and modeling work on the dissociation of polycyclic aromatic hydrocarbons in interstellar environments and the formation of new molecular species through the fragmentation process.

This dissertation approaches collections of Andean mummies in European national and university museums as the focus to understand the relationship between objects, documents, and the practice of collecting in the period from 1850 to 1930. Over 200 mummies, kept by 18 different museums in Western European…

At the Young Academy Leiden, we are closely engaged with the everyday practice of scientific research and education. From this perspective, we also contribute to the wider conversation on policy. In our policy work, we aim to be an independent and constructive voice, sensitive to current developments,…

Across Europe, the need for a more dynamic governance and a better societal integration of research and innovation is increasingly appreciated. Internal drivers of change (such as the digitalization of science) and political will to better align with societal needs and concerns are bringing about aspirational…

This focal area is concerned with the development of responsible research assessment practices. It also focuses on fostering healthy research cultures, for instance in terms of social safety and open science practices.

Over the next two years, CWTS and Dialogic will develop a robust and context-specific monitoring and evaluation framework for Open Science in the Netherlands. This will be accompanied by the development of a prototype dashboard to showcase how such an Open Science monitor could be made visible.

What is the most effective way to eliminate tumour cells? The DNA repair mechanism could play an important role in increasing the effectiveness of chemotherapy in the fight against cancerous cells. If we are to influence this mechanism, we need fundamental knowledge about how the mechanism works.

Metabolomicshas emerged as an important discipline to study molecular and cellular processes in living cells and organisms with the ultimate aim to obtain an answer to a given biological/clinical question.

An overview of research themes and projects at ABS.

Research at the SBC group is comprised of the following research themes:

It is often said that the true character of a person is only revealed in a crisis. In these days, the coronavirus causes concern about the true state of the multilateral system. Political scientist Gisela Hirschmann (Leiden University) is worried about the future of multilateralism.

This dissertation deals with Hegel’s theory of the sublime (das Erhabene). I focus specifically on die heilige Poesie (sacred poetry), a form of art that he identifies with the Judaic Psalms and which I claim to be the core of Hegel’s approach to sublimity. I claim that Hegel’s apparent lack of interest…

Using the League of Nations’ responses to early crises as an explorative historical case study, Political Scientist Gisela Hirschmann investigates how international organisations perceive and respond to existential threats.

On 29 April 2016 Rick Honings' book 'De dichter als idool. Literaire roem in de negentiende eeuw' (The poet as pop star) was presented.

Political scientist Matthew Longo (Leiden University) takes a detailed look at the evolution of border security in the United States after 9/11. Far from the walls and fences that dominate the news, he reveals borders to be thick, multi-faceted and binational institutions that have evolved greatly in…

The dissertation focuses on the work of German philosophers Theodor W. Adorno and Max Horkheimer, founders of critical theory at the Frankfurt School. Specifically, it is a study of the “early” writings, dated between 1925 and 1940, to reconstruct the early stages of critical theory. The thesis argues…

This research aims to address the relationship between cinema and political thought in Latin America, in order to question a limited understanding of cinema politics, which has dominated the field of study since the middle of the last century, and to propose a different one that we will call politics…

What drives the restrictiveness of immigration reforms? Political scientists Katharina Natter (Leiden University), Mathias Czaika (Danube University Krems) and Hein de Haas (University of Amsterdam) analysed immigration reforms in 21 Western immigration countries between 1970 and 2012. They found that…

Is there a causal mechanism underlying the decision to attack another country when on the brink of war? If so, does this mechanism differ between regime-types? Political scientist Femke Bakker (Leiden University) addresses this question from a political psychological and comparative perspective and…

When we think of politics, we tend to think of adversary, antagonism, polarisation, a struggle for power. But politics should serve positive purposes, as well. Political psychologist and meditation teacher Femke Bakker (Leiden University) thinks that positive politics is first and foremost about tolerance.…

It is difficult to hold international organisations (IOs) accountable for human rights violations. Gisela Hirschmann (Institute of Political Science, Leiden University) introduces the concept of pluralist accountability, whereby third parties set the standards for IOs’ actions in relation to human rights,…

International organisations face the challenge of balancing conflicting norms. For instance the norms governing traditional UN peacekeeping missions and the the norm of international criminal accountability. Political scientists Tom Buitelaar (Leiden University) and Gisela Hirschmann (Leiden University)…

In this PhD study, I aim to deepen our understanding of the influence of major mycorrhizal types, namely arbuscular mycorrhizae (AM) and ectomycorrhizae (EM), on the global soil carbon cycle and their potential distribution changes under future environmental shifts.

Chemical tools to monitor drug-target engagement of endogenously expressed protein kinases are highly desirable for preclinical target validation in drug discovery. Here, we describe a chemical genetics strategy to selectively study target engagement of endogenous kinases.

The application of nanomaterials in industrial processes and consumer products provides many societal benefits, but can also lead to the release of nanomaterials into the environment.
