Colonial and Global History combines a deep curiosity of transcultural processes such as imperialism, (de)colonization, and globalization with critical historical research on regional societies in Africa, Asia, and the Americas.

Statistical considerations guide the design and implementation of the experiments that scientists perform. For instance, in a clinical trial about a the efficacy of a treatment, its effect in a certain minimum amount of patients has to be observed in order to make confident assertions about the efficacy…

Inverse problems are problems where we want to estimate the values of certain parameters of a system given observations of the system. Such problems occur in several areas of science and engineering. Inverse problems are often ill-posed, which means that the observations of the system do not uniquely…

Leiden University offers many possibilities to Chinese students that want to study abroad.

Cyber security is one of the critical challenges in our inter-connected world. Organizations are being constantly targeted by adversaries. Various critical systems become exposed on the Internet. Users can find that their data has been stolen from a company that they were not even aware of.

With a joint-degree diploma in Industrial Ecology you are well prepared for broad array of career prospects in business, industry and government, as well as non-governmental organisations, universities and research institutes.

After graduation you have a lot of opportunities: academics are highly sought after in Dutch secondary education or mbo teaching. You can also aim for a management position or work as a researcher within the field of Astronomy.

Our education specializes in creative exploration and a broad understanding of scientific research and technology. It prepares students for a career involving creative and critical thinking, and in particular for a future in scientific research.

With an ever-increasing amount of data generated worldwide, industry, governments and academia highly welcome professionals with specific knowledge and skills to handle big data.

The marine shipping industry is one of the strongest emitters of nitrogen oxides (NOx), a pollutant detrimental to ecology and human health. Over the last 20 years, the pollution produced by power plants, the industry sector, and cars has been decreasing.

Biotherapeutics or biologics, such as proteins, peptides, and nucleic acids, comprise an increasing share of the pharmaceutical market, whilst offering new therapies for difficult-to-treat diseases. Most notable is their contribution to the vaccination efforts during the COVID-19 pandemic. In most cases,…

If idioms employed in codes of conduct could be as idiosyncratic as examples suggest, then to what extent did early modern language of vice, too, persist in this genre?

How can we find novel natural products from Actinomycetes that act as growth modulators on mammalian cells? Can we harvest and develop the potential of these novel compounds for industrial and medical biotechnology?

Mechanobiology is a major area in biology, however, mechanics is currently a missing element in drug development pipelines. This has led to a high cost for the society. Mechanotoxicity of drugs often appears as a long-term side effect of drugs, and has led to removal of drugs from the market. Furthermore,…

As a virtually inexhaustible source, solar energy plays a major role in future global energy scenarios.

Many handwritten and illustrated archives contain a wealth of information, but are largely underexplored because they are complex and difficult for computers to decipher. The aim of this project is to develop a digital environment that resolves this challenge and connects heterogeneous archival content…

The Ada Lovelace Distinguished Lecture Series brings outstanding computer scientists from around the world to Leiden University. The lecturers will share exciting ideas and results from the forefront of computer science.

Twenty years from now, the world population is estimated to be around 8.7 billion people, compared to the current 7.3 billion. In combination with the improvements in living standards and the corresponding growth in consumption, this will result in an enormous increase in the demand for food, consumables,…

This book focuses on policing in city-regions in Europe bringing together experts from across the continent to develop a sociology of urban policing and a unique methodology for comparing different metropolises in the same country.

Research and design are two activities that are becoming increasingly important in the Dutch subjects O&O (‘research and design’) and NLT ('nature, life and technology’). The dissertation of Tessa Vossen (ICLON and Faculty of Science) indicates that teachers and students understand the importance of…

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

Synthetic hydrogels that mimic the natural extracellular matrix in the biophysical and biochemical cues it provides to cells are in high demand, however the cell phenotypes as they are observed in vivo in numerous cases have yet to be attained.

Artificial photosynthesis aims to produce fuels from solar energy using chemical processes. In semi-artificial photosynthesis, a hybrid approach is taken using both chemical and biotechnology approaches. We aim to develop hybrid systems between light-harvesting nanoparticles and redox-enzymes (oxidoreductases)…
