In this thesis, I study 1) metabolic alterations in tuberculosis related to wasting syndrome in human patients as well as in rodent and fish animal models. 2) effects of the mutation of the leptin gene on cachexia and diabetes in rodent and zebrafish animal models.

In the Drug Research theme, we primarily work with rodents. Rodents, such as mice, are one of the most common laboratory animals. These small mammals are easily housed and exhibit a rapid rate of reproduction.

Can we find and commercialise new treatments for chronic disease that affect our ageing population? And how can we customise this research and development programme to the small but highly-developed Netherlands research economy?

Promotores: Prof.dr. P.C.W. Hogendoorn & Prof.dr. H.P. Spaink, Co-promotor: Dr. B.E. Snaar-Jagalska

The number of lions in Kenya is decreasing alarmingly, due partly to the encroaching cities and the development of the countryside. Together with local scientists and inhabitants, Leiden biologists are studying how this decline can be halted. ‘Lions are cleverer than we thought.’

The Biology programme offers 4 research-oriented specialisations corresponding with the research themes within the three institutes involved. You can choose a more practical-oriented specialisation if you would like to combine Biology with education, management business, or science communication.

How do young zebra finches learn to sing? A research team led by researcher Katharina Riebel has developed a ‘RoboFinch’ to study just that. She and colleagues in the 'Seeing voices' research consortium have spent the past four years designing the robotic bird. And with success: young zebra finches…

This project aims to develop advanced data analysis methods for monitoring and increasing our understanding on biodiversity dynamics in nature reserves such as the Oostvaardersplassen.

How does an embryonic stem cell decide if it becomes a heart cell or a kidney cell? That’s the question computational biologist Maria Mircea studied for her PhD research. She looked at the inside of individual cells to analyse how they change. This is what she discovered.

Herman Spaink knows of many substances that may help combat tuberculosis. Lab space to study them safely is very limited in Leiden. A brand-new lab at Universitas Gadjah Mada in Indonesia will soon provide a solution. About time, says Spaink, ‘The disease is on the rise and is becoming less sensitive…

As humans we have a tendency to judge certain actions as either right or wrong. Where does our moral sense come from? We found evidence that infants who are only one year old prefer those who comfort as opposed to ignore another who is sad.

The Board of Examiners consists of scientific staff members of the IBL, Naturalis Biodiversity Center and CML, who teach in the biology programmes. They are appointed by the Board of the Faculty of Science and act independently from the research institutes. The responsibilities of the board include…

The main aim of Eva's research is to create a frame of reference in which these animals as symbols must be understood, be they depicted on pottery, as amulets, as floor plans or in any other way. This frame of reference can then be used to interpret the various animal images encountered by Caribbean…

A new research line is the development of liquid biopsy fingerprints to predict early Alzheimer’s disease (AD) stage in human in readily accessible body fluids in human (in collaboration with: Dr. Geert-Jan Groeneveld, CHDR; Prof. Elga de Vries, Free University Medical Center; and others).

The Biology and Education specialisation consists of 120 European Credit Transfer System (EC) points and consists of a Biology component (60 EC) and an education component (60 EC).

Acute stress seems to have a surprisingly positive effect on our health. Researcher Erin Faught received an NWO veni grant to find out why that is and how we can use that knowledge to our advantage. For her lab research, she uses a remarkable small animal to learn more about our own stress levels.

The IBL-office welcomes you and will answer all your questions regarding general information, administrative issues, or redirections towards IBL subdivisions and people.

In the last couple of decades an ‘animal turn’ has taken place in the social sciences. This has led to a call to study social issues by including non-human animal perspectives. This Collaborative Research Group thinks it's high time that African Studies joins the chorus of minds that try to contribute…

At Molecular Physiology we teach the following courses within the Leiden Institute of Chemistry's Chemistry and Life Science and Technology programmes.

Marie-Jeanne Holveck and Katharina Riebel from Behavioural Biology at the Institute of Biology at the Faculty of Science published their research in Proceedings B of The Royal Society.

On the 1st of October a new project funded by the Joint Industry Programme (JIP) started at the IBL on the potentially negative effects of sound on fish. Behavioural biologist and bioacoustic specialist Dr. Hans Slabbekoorn leads the international research team.

Roeland Merks is appointed as professor Multiscale Mathematical Biology (0.2 FTE) at the Mathematical Institute as from 15 January 2014.

The specialisation enables you to understand the fundamentals of management and entrepreneurship alongside high quality Biology research.

Actinobacteria are Gram-positive bacteria that have a complex multicellular life cycle and are well known for their ability to produce a wide range of bioactive natural products (NPs).

Microbial Sciences'contribution to the Development & Disease research theme is to perform world-class research to understand cellular morphogenesis, growth, development and virulence of microbes.

The Advisory Board of the IBL consists of five eminent scientists with specialist expertise in complementary disciplines. They all have prominent positions for the field of Biology in the Netherlands outside our own institute.

The PR-Committee aims at developing an optimal image of the Institute of Biology Leiden (IBL) among future and current students, teachers of biology at high schools, academics outside and within the institute, journalists, interested laymen, Bioscience industrial parties and Leiden citizens.
