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…

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.

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…

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.

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.

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.

Making systems biology modelling a central pillar of research in biology

The Programme Committee Biology (Opleidingscommissie Biologie, OCB) consists of four teaching staff members and four 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…

Research on heredity and diseases is simply not possible without programmers. Curious about how you can use your IT and biology skills to deal with real-life sickness and health problems? If so, Bio-Informatics in Leiden could be something for you.

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.’

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.

The master’s specialisation Biology and Business Studies at Leiden University bridges science and business development by focusing on areas such as technology management, innovation, entrepeneurship, operations, and decision making.

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…

The CMCB brings together microbial cell biology expertise in Leiden. It aims at optimal resonance between the groups and maximal exploitation of the available infrastructure and to develop innovative cross-boundary technology platforms.

LUMC Technology Focus Area (TFA) Data Analytics is een samenwerkingsverband van verschillende onderzoeksgroepen in het LUMC die nieuwe kwantitatieve en computationele methodologie ontwikkelen voor biomedisch en klinisch onderzoek.

In this research group, led by Dr. Joost Beltman, the aim is to employ mathematical and computational dynamical modelling approaches in order to quantitatively and mechanistically understand the dynamical behaviour and regulation of intracellular networks of genes, proteins and metabolites as well as…

The master’s specialisation Biology and Science Communication and Society at Leiden University bridges the gap between experts and the public by combining high quality research in biology with extensive training in science communication.

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.

Mission: The Environmental Biology department aims to increase the scientific understanding of how current and emerging anthropogenic threats affect biodiversity and ecosystem services. Through this understanding they facilitate strategic management of natural resources by addressing urgent challenges…

We developed the bitterling as a unique, well-studied model organism in the area of the evolutionary ecology of brood parasitism. The bitterling-mussel relationship, interspecific mussel host preference, and mussel gill structure are studied in detail, to help understand the developmental adaptation…

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.

Balsaminaceae is a diverse plant family characterized by a huge floral morphological diversity.

The availability of complete plant genome sequences together with the ever increasing amount of data on the molecular, cellular and physiological mechanisms of plant development require mathematical and computational models to obtain a complete overview of and generate new insights into the quantitative…

The Horizon 2020 project Sybil-AA (Systems Biology of Alcohol Addiction) focuses on modeling and validating disease state networks in human and animal brains for understanding pathophysiology, predicting outcomes and improving therapy in alcohol addiction. Alcohol addiction, the most severe form of…

In this thesis, we describe the potential of cell mechanical phenotyping for immune cell characterization, diagnosis, drug testing, as well as treatment of disease.

We study cell-fate decision-making using embryonic stem cells as a model system. Stem cells integrate a large number of cues to direct their development into a great variety of cell types.

In this thesis we will explore the use of fuzzy systems theory for applications in bioinformatics.

Can the venom of snakes, scorpions and other animals be sources of new antibiotics?

FAIRDOM consortium is an open initiative of various partners including funding programmes, large-consortia, institutes, small groups as well as individuals.

Is it possible for sugar patterns on cells to activate the immune system to combat cancer?

Neurodegenerative diseases, including Parkinson’s disease (PD), are increasing in prevalence due to the aging population. Despite extensive study, these diseases are still not fully understood and the lack of personalised treatment options that can target the cause of the diseases, rather than the symptoms,…

During embryonic growth, cells proliferate, differentiate, and collectively migrate to form different tissues at the right position and time in the body.
