Biodiversity enables ecosystems to thrive through the synergy of functional differences among organisms. While human well-being strongly depends on biodiversity-driven ecosystem services, human actions are also at the root of current unprecedented biodiversity declines.

This thesis pioneers diatom molecular identification and quantification through genome-scale methods, with four key aims: (i) reviewing DNA/RNA sequencing methods in aquatic biomonitoring to highlight their strengths and limitations;

In September 2023, we started transforming a under-utilised outdoor space into a greener and more biodiverse garden in which all students and staff of the Schouwburgstraat can relax and enjoy.

Radio jets are important to the evoultion of galaxies. However, it is still not fully understood how a radio jet can be triggered.

The transition from single cells to multicellular organisms was a key step in evolution. Researchers from Leiden and Amsterdam developed a mathematical model that explains how this transition may have come about. They suspect cooperating cells may correct each other’s mistakes. Publication in eLife…

The research that is united in the Liveable Planet programme, touches upon a wide range of aspects of human life. The goal is to deepen and expand the scope and to connect more researchers. The following case studies are examples of current research projects.

Venomous animals serve as models for a variety of mimicry types. Michael Richardson (IBL) and his international colleagues find that a group of fishes (called fangblennies) evolved venom after the origin of their venom-delivering fangs.

On Saturday 23 and Sunday 24 February, the yearly ‘Algant doctorate candidates and academics’ meeting will take place. The Algant Consortium consists of 8 universities on 4 continents and offers a two-year integrated master and a joint doctorate programme in pure mathematics, with a strong emphasis…

This thesis explores the theoretical and observational properties of distant massive galaxies that harbour active black holes in their centres and shine brightly at radio wavelengths.

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.

In this dissertation iron-based homogeneous catalysts were synthesized, characterized and investigated for water oxidation activity.

Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

This dissertation studies the Asymptotics of Bayesian nonparametric inference for Gaussian linear models.

This thesis aims to address offshore wind energy (OWE)-related environmental impacts.

How can we make the information in handwritten historical research reports accessible and searchable? Data scientists at Leiden University are working with other universities on a method that will improve access to cultural heritage.

Do you live in Egypt and have you always wondered about all the pharaonic heritage surrounding you? This spring NVIC organizes a beginner’s level, introductory course in Egyptology. In 6 richly illustrated lessons, the history of ancient Egypt will be brought to life, both chronologically as well as…

On Thursday 11 November, Women in International Security Netherlands (WIIS-NL) held its inaugural webinar event on 11 November with four speakers in conjunction with the International Centre for Terrorism (ICCT) and the Chair UN Studies in Peace and Justice at Leiden University.

To design the ideal water oxidation catalyst, understanding of the catalytic mechanism and decomposition pathways is essential.

This thesis aims to enhance our understanding of galaxies by testing theoretical models of galaxy formation against observations, particularly in the cases of extreme systems which have been found to have an excess of baryonic mass in their central regions, in the form of either supermassive black holes…

The Biology programme offers 4 research-oriented specialisations corresponding with the research themes within the three institutes involved. You can choose a more practical-oriented specialisation if you would like to combine Biology with education, management business, or science communication.

Developing methodes to understand the evolution of patches in natural ecosystems

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.

We examine how soil-derived legacy effects of plants structure natural ecosystems, determine aboveground plant insect interactions, and how we can use soil legacy effects to restore degraded ecosystems.

One of the key quests in astronomy is to study the growth and evolution of galaxies across cosmic time. Radio observations provide a powerful means of studying the formation of stars and subsequent buildup of distant galaxies, in a way that is unbiased by the presence of dust.

This thesis describes the use of the evolutionary approach in the study of language change, aiming to provide a better insight in the mechanisms that play a role in language change and to validate this approach in the field of language change.
