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…

Which basic characteristics and skills and knowledge influence the use of and actions based on real-time student data presented on a teacher dashboard in primary education?

The Netherlands returned 478 artefacts to Indonesia and Sri Lanka this week, on the advice of a Dutch committee. Rightly so, says Leiden professor Pieter ter Keurs from the Museums, Collections and Society interdisciplinary research programme. ‘But do make it clear why you are returning something.’

Treatment and care for cancer patients is becoming increasingly advanced. For example, surgeons can now perform operations with much greater precision, and therapeutic vaccines are being developed to prompt the patient’s immune system to fight cancer. Work is also being done on better early diagnostics,…

The Chemical Probe Facility is part of the Leiden Early Drug Discovery & Development (LED3) center. Activity-based protein profiling (ABPP) is one of the pillars of chemical biology. ABPP determines the activity of entire protein families in living cells and tissues under physiological conditions, such…

Core Facilities are shared resources that provide access to instruments, technologies and services to researchers across the Institute of Biology. They are staffed by scientists with vast experience in their field, ensuring that all researchers can count not only on the latest available technology…

The goal of hit and lead optimization is to optimize suitable chemical starting points that can modulate a drug target. The methods and technologies used are similar to those in Hit Discovery, but once the compound has shown activity in an animal model, it moves from 'hit' to 'lead.'

The work done by SUMO proteins in the cells of our body is of vital importance. Molecular cell biologist Alfred Vertegaal has been studying these proteins for nine years, first with a Veni subsidy and then with a prestigious Vidi subsidy.

How and to what extent does AI affect citizen representation in public service delivery and state-citizen interactions?

Leiden University has awarded its prestigious University Medal to Emeritus Professor Lex van der Eb. As a pioneer in genetics and molecular biology, he received this honour for his services to science and his key role in the development of the Leiden Bio Science Park (LBSP).

From receiving our salary to doing our shopping: we are completely dependent on commercial banks for all our payment transactions. But what happens if they collapse? In his inaugural lecture, Professor Bart Joosen calls for a rigorous change: ‘Put payment transactions for private clients under one…

How are law and governance in China responding to rapidly changing circumstances, and what does that mean for the relationship between the state and its citizens?

Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

Vice-rector Organisatieontwikkeling en oud-decaan FGGA Erwin Muller start op 1 april 2026 als staatsraad bij de Afdeling Advisering van de Raad van State.

How do lipases in Mycobacterium tuberculosis help the bacteria survive, and can we target them to create new antibiotics?

Some people are predisposed to develop cancer. Mutations in genetic material that increase a person’s chances of developing cancer can already be present at birth. Researchers are closely examining these mutations to learn more about how cancer begins to develop.

The CMCB comprises research groups from the Institute of Biology Leiden (IBL), the Leiden Institute of Chemistry (LIC) and the Leiden University Medical Center (LUMC).

The discovery of new medicines is a tedious and lengthy process. On average, over 10,000 molecules need to be studied for one to become a drug and reach the patient. Part of that process are the very costly clinical trials in humans, and candidate drugs often fail due to side effects or lack of efficacy.…
