We perform multidisciplinary research at molecular, cellular, and organismal levels of animal biology to increase fundamental understanding of health and disease.

Animal Sciences’ contributions to the Development & Disease research theme include the mechanisms and evolution of embryonic development, the development of cognitive mechanisms, and animal models for understanding mechanisms of human disease.

Animal Sciences’ contributions to the Evolution & Biodiversity research theme include evo-devo research, the evolution of cognitive and behavioural traits, and the evolutionary mechanisms of stress adaptation. This research involves both indoor and outdoor studies.

Nature is a never-ending source of inspiration for the researchers at the Institute of Biology Leiden (IBL). Based on a better fundamental understanding of nature, they are able to seek solutions in the area of health and biodiversity. The theme of IBL is ‘Harnessing biodiversity for health.’

We carry – and also feel – great responsibility for our laboratory animals. Animal welfare is very important to us. You can read below how we safeguard the welfare of our laboratory animals.

Animal Sciences’ contribution to the Bioactive Molecules research theme includes research on molecules from natural sources, such as plants, insects, and snake venom, with the aim to identify novel anti-cancer, anti-inflammatory, anti-microbial, and anti-diabetic agents.

Chemical biology research at the Leiden Institute of Chemistry is aimed at understanding biological processes at the molecular level to strengthen the knowledge base of human health and disease. The approach to achieve this goal is a fundamental chemical one; with the aid of chemical probes biological…

This research programme aims to increase the scientific understanding of how current and emerging anthropogenic threats affect biodiversity and ecosystem services to facilitate strategic management of natural resources. To this end, we address urgent challenges in relation to the mechanisms involved…

Animal Sciences’ contributions to the Host-Microbe Interactions research theme focus on the interaction of animal hosts with pathogenic microbes but also the beneficial role of the gut microbiome.

PhD candidates carry out a programme of independent research and additional (limited) course work, culminating in production of a PhD thesis in typically 4 years.

All biological and bio-medical research carried out at Leiden University is subject to strict conditions.

We only conduct research using laboratory animals if it is absolutely essential and we have no other means of answering the research question. Read here about how we assess and account for this research.

What does the interspecies interpretation of the equality principle mean for the liberal democracy, and is it possible to provide for an appropriate legal and political position for animals without defying the classic-liberal principles of the liberal democratic state?

This programme video is presented in Dutch

The Institute of Biology Leiden (IBL) is an internationally oriented institute for research and education in biology. We are part of the Faculty of Science at Leiden University.

In the theme Animal sciences and health research, we work with different species of animals to learn more about fundamental biological processes.

This thesis aims at thinking through the ethical position of animals in a way that differs radically from the manner in which this ethical position is thought within contemporary animal rights discourse.

The master's specialisation Molecular, Cellular and Organismal Biology at Leiden University examines the molecular mechanisms underlying health and disease and how cells and organisms adapt to environmental factors.

Main challenges in skin vaccination are overcoming the stratum corneum (SC) barrier and targeting the antigen presenting cells (APC) in the epidermis and the dermis.

The master’s programme Biology at Leiden University offers seven specialisations ranging from Cell Biology to Molecular Genetics. The programme prepares you for a career in research within or outside academia.

Biology is the study of life. Are you interested in understanding life, from the molecular level to entire ecosystems? Do you want to use your understanding and knowledge of biology to benefit the health of both humans and the environment? If so, Biology is the right study programme for you.

Quantitative biology means exploiting mathematical modelling and computer simulation as a tool to gain additional insights into the meaning of experimental data. Discover in this minor when and how to apply these tools, in a multidisciplinary setting.

To address biological questions related to human health, chemical tools are essential. Covalent or non-covalent interactions of compounds with biomolecules offer a range of possibilities for study. They can be used to identify enzymes based on their activity, to influence cellular regulation, by changing…

This part entails the analysis of an extensive sample of animal bone (c. 30,000 pieces) retrieved from well-defined archaeological contexts of the early period at Tell Sabi Abyad, c. 6800-6200 BC. It comprises aspects of taphonomy, ageing and osteometry, the reconstruction of the local spectrum of domestic…

The Animal Welfare Body is closely involved in all aspects of the research on laboratory animals.

Projects within the theme ‘Computational Biology’ aim to employ mathematical or computational dynamical modelling approaches to discover novel concepts that are important for drug development.

Chemical biology research at the Leiden Institute of Chemistry is aimed at understanding biological processes at the molecular level to strengthen the knowledge base of human health and disease. The approach to achieve this goal is a fundamental chemical one; with the aid of chemical probes biological…

Keeping and breeding of test animals for the purpose of scientific research and education.

Brendan Carroll promoted On Thursday October 30th Brendan Carroll successfully defended his PhD dissertation entitled:

Did early farmers deliberately use animal manure on their fields?

The master’s specialisation Biology and Education at Leiden University prepares students to teach the subject of biology to secondary school students. The programme comprises a one-year Biology component, followed by an education component in the second year.

The master’s specialisation Evolutionary Biology at Leiden University investigates biology at all levels. The specialisation includes genomics, functional developmental genetics, paleobiology, behavioral biology and evolutionary ecology.

A theoretical project on the insights gained by human (including infant), nonhuman animal and computational studies on artificial grammar learning; identifying the critical questions for future research by developing novel experimental and computational approaches to address these issues.

The Programme Committee Biology (Opleidingscommissie Biologie, OCB) consists of four teaching staff members and five students, and is assisted by the study adviser. The OCB has an independent position within the Biology education program. Because of its composition, the OCB is the most important organ…
