Biologist Marcel Schaaf is one of four science faculty members who achieved the Senior Teaching Qualification in Leiden last year. How was that and what drives him? ‘Students receive way too often feedback that they cannot put into practice.’

The IBL Education Office consists of:

How can novel bioimaging technologies and vertebrate model species be used to gain a better understanding of early cellular behaviours with the ultimate goal to increase our understanding of human development and disease processes?

Daily management at the Institute of Biology Leiden is executed by the Scientific Director, the Director of Education, the Director of Operations and the Management Assistant. Research and education are managed collaboratively, with strategic input from various representatives and gremia, including…

To what extent is sound a stressor to fish? And are behavioural and physiological phenotypes equally sensitive to disturbance by noise pollution?

Visualization of biomolecules in living cells by tagging with gold nanoparticles.

Unraveling the immune-suppressive actions of drugs like prednisone.

How can zebrafish research help understanding human diseases?

Promotores: Prof.dr. H.P. Spaink & Prof.dr. P.C.W. Hogendoorn, Co-promotor: Dr. M.J.M. Schaaf

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’ 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.

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.

Due to the corona crisis, they had to switch to online education halfway during their course: associate professor Marcel Schaaf and PhD candidate Michiel Hooykaas of the Institute of Biology Leiden talk about digital practicals, online lectures and their biggest obstacle: exams.

From 1 October onwards, Dennis Claessen and Marcel Schaaf will be the new directors of education of Biology. They will replace Han de Winde. Schaaf will be responsible for the bachelor, while Claessen will mainly focus on the master tracks of Biology. We gave students and the education office the change…

What are the host immune defence mechanisms that control intracellular infections and how are these subverted by pathogens?

From 1 October, two new Directors of Education will start at the Institute of Biology Leiden (IBL). Dennis Claessen as the new director for the master's programme of Biology and Marcel Schaaf as director for the Biology bachelor's programme. Claessen and Schaaf have been appointed for a period of four…

Advanced fluorescence microscopy techniques have revealed how steroid receptors move inside the nucleus. The results were published by a team from Leiden University and the Erasmus Medical Center in Rotterdam, led by IBL-researcher Marcel Schaaf.

Students of the Biology minor course Molecular Design have successfully boosted their skills in collaboration, research and writing with the recently developed E-learning Skills Platform. The biology students and their teachers greatly value the initiative. ‘Sometimes I couldn’t believe what progress…

The construction of the new building for the Faculty of Science is in full progress. The Cell Observatory of the Institute of Biology Leiden will be moving to the new building in the beginning of 2016. Professor Annemarie Meijer and Dr. Marcel Schaaf had a sneak preview.

A novel in vivo model system for studies on glucocorticoid resistance

We are developing the conceptual framework, which is new to this taxonomic group, and evaluate the current state of the art with respect to all critical parameters and transfer functions for a fully developed Population Consequences of Acoustic Disturbance (PCAD) model.

A consortium of researchers from the Leiden Institute of Physics (LION), the Institute of Biology Leiden (IBL), and the Leiden Institute of Chemistry (LIC) received a FOM program grant to develop a novel way of studying individual proteins inside a cell using gold nanorods.

The Horizon 2020 project ImageInLife has started on 1 January, followed by a kick-off meeting at the coordinating University of Montpellier at the end this month. This Marie Skłodowska-Curie training network brings together European groups that work on the imaging of vertebrates and offers fourteen…

Alexander Kros studies supramolecular systems in a biological environment. The unifying theme between the projects in my lab is specific molecular recognition, i.e. the intermolecular interaction between complementary molecules with high affinity and selectivity. Studying, imitating and dissecting processes…

At the New Year’s reception of the Faculty of Science on 6 January, it was announced that Annelien Zweemer, Leiden Academic Centre for Drug Research, has been awarded the ‘Discoverer of the Year 2014’ prize. Matteo Brogi, Leiden Observatory, wrote the best dissertation in 2014 and Dennis Claessen, Institute…

How do you microscopically image zebrafish larvae? The new free online course ‘Imaging the Vertebrate embryo’ teaches you all about it. Leiden PhD candidates Salomé Muñoz Sánchez and Radoslaw Gora contributed to the course.

Out of fifteen Senior Teaching Qualification certificates (SKO) awarded by the University this year, four go to the Faculty of Science. With congratulations from Rector Hester Bijl, the enthusiastic lecturers receive the certificate for their exceptional commitment, skills and impact within the Univ…

Proactive zebrafish appear to have a much stronger wake-sleep rhythm than reactive fish. In the most reactive fish, rhythmicity appears to be lacking completely. This is shown with research by Leiden biologists, published in December 2018 in the journal BMC Biology.

Poetry, video editing, musical art: the first installment of the 48 Hour Project, in which students created a piece of art in only two days, has resulted in a wide variety of creativity. For participants, it was a glimmer of light in a rather dark year of lockdowns: “I felt like I was physically there with…

Nanoplastics influence the behaviour of larval zebrafish, says new research by the Institute of Biology Leiden (IBL) and the Institute of Environmental Sciences (CML). The researchers observed that a certain type of nanoparticles leads to stress reactions in the sugar balance, resulting in hyperactivity…

An overview of awards and prizes granted to our staff and students in 2020, as well as special appointments at Leiden University and other institutions.

Bringing together institutes and research groups, how do you do that? The Faculty of Science set up a joint research theme and financed three PhD positions. After four years, the profiling programme Endocannabinoids expires. ‘It really brought us together, and the collaborations remain.’
