The Data-Driven Drug Discovery Network (D4N) is an initiative by researchers from Leiden University and collaborators to join efforts in applying and developing novel techniques from data science to drug discovery and related topics from bioinformatics.

Can we develop a tool to early identify male chicken eggs?

Supervisor: Gerard van Westen

This thesis describes a study from both a theoreticaL and an experimental point of view.

Despite the history of studies on methanol formation from CO2, the dominant elementary reaction steps that constitute the chemical mechanism for this catalyzed process are not determined.

Hybrid zones occur where two species meet and produce offspring (hybrids). Typically, hybrids show a considerable reduction in fitness. In this thesis two hybrid zones are treated.

Leiden researchers have found minute movements in the laccase enzyme. This discovery could lead to the development of much more efficient biofuel cells. Publication in Biophysical Journal.

This thesis focuses on data found in the field of computational drug discovery. New insight can be obtained by applying machine learning in various ways and in a variety of domains. Two studies delved into the application of proteochemometrics (PCM), a machine learning technique that can be used to…

The formation and evolution of galaxies is fundamentally driven by the formation of new stars out of cold gas.

Developing new medicines is one of modern science's most significant hurdles, a process marked by high costs, long timelines, and frequent failures of promising candidates.

Institute of Biology Leiden (IBL) is an internationally oriented institute for research and education in biology. We are part of the Faculty of Science at Leiden University.

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

The work in this thesis demonstrates how to obtain an atomic-scale picture of a diverse set of complex surface structures observed using STM, under disparate conditions.

ChEMBL is a large-scale drug discovery database containing bioactivity information primarily extracted from scientific literature.

The recently introduced nature-originated deep eutectic solvents, so-called natural deep eutectic solvents (NADES) are considered as truly green solvents, which composed of natural ingredients found abundantly in organisms.

Scientists at Leiden University (Netherlands), Stuttgart University (Germany) and Ural Federal University (Russia) have successfully put forward a novel, computed, reaction mechanism that was experimentally tested and show that formaldehyde is formed at much earlier stages in the birthplaces of stars…

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.

Animal diet studies are critical for understanding ecological processes such as trophic interactions, energy flow, and nutrient cycling. By examining what animals consume, ecologists gain insights into species specialization, predator-prey relationships, and ecosystem management.

In the search for sustainable energy solutions, the idea of artificial photosynthesis has been proposed as an approach with which to use water and sunlight to produce hydrogen.

Prof. Gilles van Wezel and Prof. Mike Richardson of the Institute of Biology Leiden received €1.4 million to find new antibiotics.

A team of researchers at the Institute of Biology Leiden, in collaboration with scientists from Utrecht University, has discovered a novel approach to improve the production of antibiotics and enzymes in the soil bacteria Streptomycetes.

Synthetic hydrogels that mimic the natural extracellular matrix in the biophysical and biochemical cues it provides to cells are in high demand, however the cell phenotypes as they are observed in vivo in numerous cases have yet to be attained.

This thesis takes steps toward understanding the interaction between gas-phase and solid-state molecules in star- and planet-forming regions.

Microbial Sciences' contribution to the Host-Microbe Interactions research theme is to investigate how beneficial or disease-causing microbes associate and interact with their host.

Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

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 cannabinoid receptor type 2 (CB2R) is associated with several inflammatory diseases with an unmet medical need (e.g. Alzheimers, multiple sclerosis, reumatoid arthritis). Development of new chemical biology strategies to study this protein is essential to aid future development of drugs for these…

Edith Schippers, Minister of Health, will be investing six million euros over the coming four years to boost research on new antibiotics. The programme will be set up by several different parties, including the Leiden Centre for Antimicrobial Research.
