Living systems scale from unicellular microbes to complex multispecies communities that constantly change over time. Within the theme Development & Disease, we enhance our fundamental understanding of development and homeostasis of living cells and systems. We analyze the normal situation and how stresses…

“Temminck’s Order” is the scientific biography of Coenraad Jacob Temminck (1778–1850), a Dutch naturalist and the first director of ’s Rijks Museum van Natuurlijke Historie in Leiden.

Songbirds apparently use mnemonics rather than more complex grammatical rules to recognise structures in which they have been trained. Leiden behavioural biologist Caroline van Heijningen published an article on this subject on Tuesday 17 November in PNAS.

Lysosomal storage disorders (LSDs) are a group of orphan diseases characterized by lysosomal dysfunction or impaired lysosomal catabolism and affect collectively about 1 in 5000 live births.

The mission in this division, headed by Laura Heitman, is to design and synthesize novel and better ligands for drug targets. Drug discovery is a lengthy but inspiring adventure. It is often an interplay between academic institutes and pharmaceutical industry, in which scientists at university develop…

Detecting planets during their formation stages is crucial for understanding the history and diversity of fully developed planetary systems like our own. However, observing young planets directly is challenging because they are often deeply embedded within their host protoplanetary discs, rich in gas…

This thesis systematically studies the physicochemical properties of non-planar, propeller-shaped, polycyclic aromatic hydrocarbons. The synthesis of several so-called propellerenes is described on a gram scale, using optimized procedures aimed at using less hazardous reagents and reducing the amount…

The Metabolomics Facility of the University of Leiden has brought together two research groups from the Faculty of Science that are well-known for their expertise in two different fields: the Biomedical Metabolomics Facility Leiden, experts in clinical metabolomics and the Natural Products Laboratory,…

To improve treatment of breast cancer patients it is important to understand all stages of breast cancer from initiation to in situ disease and progression to invasive disease. In this thesis we use intraductal injections of patient derived tissue to model ductal carcinoma in situ and invasive breast…

Conact the Cellular Chemistry group

We aim to engineer streptomycetes to fully exploit their potential for natural product productions, by a rational design and evolution approach.

Every organisms in the tree of life faces the same challenge: the length of its DNA exceeds the volume of the cell it needs to fit in. Several strategies have evolved to solve this problem, one of them being the expression of proteins that bind and organize the DNA.

As a virtually inexhaustible source, solar energy plays a major role in future global energy scenarios.

This thesis describes the use of bioorthogonal proteins in immunological settings. It provides an introduction towards the field of protein modification, which was used throughout the thesis for the expression of proteins containing unnatural amino acids.

In this thesis, bioorthogonal chemistry is combined with correlative light-electron microscopy to selectively label and study pathogenic intracellular bacteria within the host immune cell.

The research described in this thesis focused on the use of bioorthogonal antigens to investigate immunological processes in antigen presenting cells. Bioorthogonal antigens are antigenic proteins produced through recombinant expression in a methionine auxotrophic E. coli strain.

Your time at Leiden is about more than just studying. Some of your best experiences will stem from being a part of our lively and diverse student community, as well as from life in the beautiful city of Leiden.

We are committed to provide you a meaningful, rigorous and quality graduate experiences in a personalized environment with a cutting edge research infrastructure and internationally renowned supervisors

Research at the BIOSYN group is comprised of the following research themes:

The chemical industry must continue to innovate for a more sustainable, healthier society. The reseachers from the Leiden Institute of Chemistry (LIC) contribute by applying their knowledge to themes such as sustainability, energy and health.

The IBL Education Office consists of:

The Joan van der Waals colloquium is an ongoing bi-weekly lecture series.

The new book of Professor of Character evolution and biodiversity Menno Schilthuizen gained a lot of media attention. ‘Darwin comes to town – how the urban jungles drives evolution’ was published in English in February and will be available in Dutch soon.

NL-BioImaging AM is a distributed research infrastructure aimed at promoting progress in the most cutting edge microscopy technologies and providing open access to these technologies to a broad community of academic and industrial users. All Netherlands bio(medical) microscopy centers participate.

Twenty years from now, the world population is estimated to be around 9 billion people (now 8 billion). In combination with the improvements in living standards and the corresponding growth in consumption, this population will result in an enormous increase in the demand for food, consumables, water…

Research and education at the Leiden Institute of Chemistry is overseen by the Institute Board. The Board and representatives of the two research themes form the Management Team. The Scientific Council (WERA), the Institute Council (I-Raad) and the platform for PhDs and post-doctoral co-workers (LIC73)…

Professor Fons Verbeek of the computer science and biology institutes at Leiden University has the fascination to visualize everything we can not see immediately. At SleutelstadFM he tells us that by converting 2 dimensional (2D) images to 3 dimensional (3D) structures, research is carried out into…

Mario van der Stelt (Head of the department of Molecular Physiology at the Leiden Institute of Chemistry) has received the Young Investigator Award from the International Cannabinoid Research Society during the annual meeting of the society in Montreal, Canada. The Young Investigator Award was given…

Nucleoid associated proteins maintain the architecture of the bacterial chromosome and regulate gene expression, hinting that their role as transcription factors may involve local three-dimensional chromosome re-modelling.

Through his project we will unravel the global regulatory networks that control gene expression in Streptomyces bacteria and allow them to properly respond to major changes in the environment; we will then harness this knowledge to activate and identify novel antibiotics

The probability for dissociation of molecules on metal surfaces, which often controls the rate of industrially important catalytic processes, can depend strongly on how energy is partitioned in the incident molecule. There are many example systems where the addition of vibrational energy promotes reaction…

Microbial Sciences' contribution to the Biodiversity & Evolution research theme focuses on understanding how bacteria sense and respond to their environment, and how bacterial diversity and evolution is influenced by cooperative and antagonistic interactions taking place between microbes.

The imaging group focuses on bio-imaging, image analysis and visualization.

Neuraminidases are enzymes that cleave glycosidic linkages of sialic acid. These enzymes are involved in influenza infections as well as in many cellular processes in mammals and micro-organisms.

Multicellular giant algae Chara species have been widely used in physiological studies for decades.
