With the powerful electron microscopes at NeCEN we study abnormalities in cells of blood vessels in cardiovascular disease, the interaction between pathogens and hosts in infectious diseases, molecular processes that cause cancer and the interaction between drugs and target proteins. Drug development…

Can we distinguish the effects of pesticides from other abiotic and biotic factors that occur in the field? And how do these factors interact with pesticides?

As a non-invasive genetic method, eDNA based approaches have become an important component of ecologists' and environmental managers' toolkits for biomonitoring in conservation and an increasingly important source of ecological knowledge.

Freshwater and brackish water ecosystems are arguably the most vulnerable ecosystems on earth, due to concentrated human developments in and around them. The Pontocaspian (PC) region located at the border of Europe and Asia contains a variety of brackish water ecosystems and unique inhabitants, known…

What is the role of auxin in the initiation and process of somatic embryogenesis?

The new institute manager of the IBL studied biology for six months, but went in a completely different direction: development cooperation and the financial sector. Three decades later, Resi Janssen is making a radical career switch. Or isn’t she? 'In ten years’ time I want IBL to be in a new, sustainable…

Several techniques are explored for going beyond the born-oppenheimer static surface model for molecule-surface reactions.

The idea that modern humans displaced Neanderthals because they were better protected against toxic smoke components is now under fire. An earlier study that put forward this suggestion has now been refuted by genetic research by scientists from Leiden and Wageningen. This new research was published…

What chemicals do plants have available, and what happens if they use them when faced with bacteria or fungi? That is what PhD candidate Luis Salomé Abarca is keen to learn. He studies plants’ survival and their use of chemical components in communication and defence. Salomé Abarca works at the Natural…

Leiden University finds it very important that you choose the study programme that is right for you. That’s why we offer so-called matching activities, to help you in your decision.

The AiChemist project (https://aichemist.eu) coordinated by Helmholtz Munich is an Innovative Doctoral Training Network funded through the Marie Skłodowska-Curie Actions (MSCA-DN) within the EU Horizon Research Framework, to the sum of €3 million. It brings together leading experts in AI, chemoinformatics…

Coordination chemistry is the chemistry of metal atoms

The Leiden Science Young Talent Award is awarded yearly to a student who completed their bachelor’s degree with an excellent thesis.

The bacterium Vibrio cholerae is a serious threat to our health because it is the causative agent of cholera. Worldwide, over a billion people per year are at risk of cholera infection. New strains of V. cholerae are resistant to the multiple drugs used to treat cholera, meaning that new types of drugs…

Medical Delta has appointed seven professors who will bridge the medical worlds of Leiden, Delft and Rotterdam.

With a self-converted red camper van, biologists and twin brothers Kevin and Marvin Groen go on a nature adventure in Eastern Europe. Together, they search for wild animals, beautiful nature and places to sport. From a long search for a bear in the Slovakian wilderness to the discovery that pelicans…

Nathaniel Martin has been appointed professor in the field of Bioorganic Chemistry within the Faculty of Science at the Institute of Biology Leiden, starting from 1 March 2018. His research focuses on using new (bio)chemical approaches to combat infectious disease, as well as on developing new molecular…

Methods of treatment for chronic illnesses are limited. Doctors and researchers at Leiden University Medical Center (LUMC) and Leiden University are working on new therapies as an alternative for organ transplants. The goal is to cure the illnesses by restoring organs to their original function. Stem…

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

Huub de Groot is professor in Biophysical Organic Chemistry. With his team he works in the field of photosynthesis and artificial photosynthesis. The molecular basis for photosynthesis is formed by protein complexes and organelles that contain chlorophyll molecules. The antenna systems herein capture…

An overview of awards and prizes granted to our staff and students in 2017, as well as special appointments and royal distinctions.

This research group, headed by Miranda van Eck, focusses on understanding the molecular mechanisms underlying cardiovascular and metabolic diseases. Cardiovascular disease constitutes a major health issue worldwide. Although significant knowledge has been obtained on the development of atherosclerotic…

This thesis presents pioneering work on the panchromatic emission of some of the most luminous galaxies in the early Universe: star forming galaxies and active galactic nuclei.

Lichens enthusiast Sander van Zon was eager to use his knowledge for his internship. He wrote an excellent thesis on lichens’ biodiversity in the city, of which his first scientific publication will appear soon. With it, he is nominated for the Leiden Science Young Talent Award 2022.
