The IBL represents the core of modern biological research at Leiden and we interact closely with the other life science Partner Institutes in the faculty:

Research groups in the Quantum Matter & Optics programme investigate electronic properties of matter and light-matter interactions with emphasis on quantum information.

Can zebrafish provide a fast, sensitive in vivo vertebrate model for identifying novel mechanisms of Ewing sarcoma progression and for development of new anticancer compounds in a time- and cost-effective manner?

For many years, human rights have been considered a playing field in which states were the most important actors. In the present day society, this has changed as a consequence of globalization and the rise of multinational enterprises (MNEs). Protection of fundamental labor rights in global supply chains…

This research cluster explores processes of cultural creation, reception and transformation within a wide range of societal contexts from the early Middle Ages until c. 1800.

Carbohydrates, alongside proteins and nucleic acids, constitute a crucial and versatile family of biomolecules present in all life forms. They manifest as monosaccharides, oligosaccharides, and polysaccharides, covalently bonded to proteins and fats. Carbohydrates are integral to plant and arthropod…

Polarisation in our society is on the rise. What makes people increasingly radical? How do we protect ourselves from extremist, terrorist or criminal threats, be they physical or in the cyber world? And what role do intelligence services play in this?

The lipid matrix in the stratum corneum (SC), the upper layer of the skin, plays a critical role in the skin barrier. The matrix consists of ceramides (CERs), cholesterol (CHOL) and free fatty acids (FFAs).

With a MSc in LST you are well prepared for a wide range of career opportunities. Life Science research and business is one of the fastest growing economic activities worldwide.

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

The lipid membrane is a basic structural component of all living cells. Embedded in this nanometer-thin barrier, membrane proteins shape the membrane and at the same time respond to the shape of the membrane.

Despite recent advances in medicine, many devastating disorders like cancer and cardiovascular, neurodegenerative and infectious diseases still lack effective treatments. In order to address this challenge, we, as scientists from Leiden University, joined hands in the LED3 network. LED3, for Leiden…

What are the genes and molecular mechanisms involved in bacteria-mediated plant drought tolerance?

Research carried out at Leiden University contributes to our knowledge of sustainability. This is essential if we want to work together to find solutions to pressing issues, such as the current climate emergency and the shortage of raw materials.

At Leiden University, in both our biomedical and biological research, we use laboratory animals. Learn more about these specific areas of research and the goals we aim to achieve through these studies.

The Law of the European Union is a complete reference work on all aspects of the law of the European Union, including the institutional framework, the Internal Market, Economic and Monetary Union and external policy and action.

The programme consists of multiple courses and will teach you about a range of legal, regulatory and ethical issues with respect to digital technologies.

The making of sacrifices seems part and parcel of any elite sportsperson’s life. Remarkably, the insights that we find in the current literature in social sport studies are not able to make sense of the references to sacrifice in the data that emerged in the context of this study on the social significance…

n this PhD thesis, the recombination of different atomic lattices in stacked 2D materials such as twisted bilayer graphene is studied. Using the different possibilities of Low-Energy Electron Microscopy (LEEM), the domain forming between the two atomic layers with small differences is studied.
