Fleur Visser was awarded a Veni grant by the Netherlands Organisation for Scientific Research (NWO). She is one of seventeen promising young Leiden scientists, who get the opportunity to develop their own ideas over a period of three years. Veni-funding is part of NWO's Talent Scheme, concerning…

A team of researchers at Leiden University is collecting information about the methods used by researchers in the field of public international law. The research team consists of Cecily Rose, Misha Plagis, Johanna Trittenbach, and Nicholas McGuire. The goal of this research project is to understand…

Leiden University stands for high quality research. Integrity and reliability in the way we conduct research are core beliefs in Leiden.

Anthropogenic change is reshaping ecological systems, raising concerns about increasing transmission of infectious diseases. Among these, mosquito-borne diseases may be particularly sensitive to environmental change, as their transmission depends on vector populations.

This thesis describes the antimicrobial discovery strategy developed in our group, the den Hertog Group at the Hubrecht Institute. It includes a cultivation-based screening approach for novel antimicrobial agents from the source of fungi, and a bacterial time-lapse imaging approach for antimicrobial…

In this latest contribution to mimetic studies, Nidesh Lawtoo joins forces with leading international theorists of the posthuman to broaden the reach of the mimetic turn beyond human imitation.

Cities need to become greener, more biodiverse, and climate-resilient. However, many organisms that are vital for the functioning of urban green spaces and the wellbeing of urban citizens remain largely unknown.

Report on the Excavations of the National Museum of Antiquities Leiden in the Balikh Valley, Syria.

The Laboratory for Archaeozoological Studies is an advanced laboratory with advanced Leica stereomicroscopes and measuring instruments and an extensive reference collection which is used for research e.g. the identification of fossil remains. The collection is also used for teaching students the anatomy…

This thesis has described novel synthetic methods to produce a variety of (glyco)peptides and their application in the study of various immunological processes.

Developing a new way to measure marine biodiversity at high resolution, by listening to it.

The handbook is a wide-ranging survey of a crucial period in prehistory during which many social, economic, and technological changes took place. Written by specialists in the field, the book provides coverage both of the themes that characterise the period, and of the specific developments that took…

This project aims to study the Aesopian fable from 1500 to the present day in its complex relationship between text, illustration and education, adopting a broad, transnational perspective.

The predication of the effect (efficiency and toxicity) of a drug in a patient is very important in (i) clinical decision support and (ii) the development of novel drug treatments.

Investigating the relations between Tupi Indigenous Knowledge, Museum Collections and the Dutch Colonization of Brazil

The aim of this research area is to be able to predict human drug response on the basis of mathematical models that are developed using preclinical experiments and prior knowledge.

In this thesis, two potential therapeutic targets for diabetic nephropathy were dentified and investigated. First, we show that glomerular clusterin is upregulated in diabetic nephropathy and demonstrated that recombinant clusterin protein can protect the podocytes against oxidative stress in vitro.…

Human vocal communication and music perception represent advanced cognitive skills, seemingly innate and universal. These faculties encompass a range of perceptual and cognitive abilities. Cross-species research sheds light on the origins of musicality by investigating whether these traits are shared…

One of the major limitations in culturing complex tissues or organs is the lack of vascularization in the cultured tissue. Development of a functional capillary bed could overcome this problem.

High-throughput holistic preclinical screens are increasingly used in drug discovery, to assess both drug efficacy and drug safety.

Investigating the making of knowledge in anthropology and natural history in colonial and postcolonial Indonesia.

In this thesis, I investigated the neurogenetic properties of Neotropical bat species. Bats represent the second largest mammalian order (Chiroptera) in the world, with Neotropical bats constituting about 13% of the total number of bat species.

The subject areas covered encompass functional genomics, signal transduction, cellular differentiation, development, host-microbe interactions and animal behaviour.

Here we provide information on the ways through which the Institute of Psychology aims to foster responsible scholarship practices: conducting research with integrity, and meeting the needs for better quality and efficiency in psychological science.

You will be trained for a career in research or for a more practical-oriented specialisation. The programme offers a wide choice of individual study paths that take into…

From passports to policy: take a moment to look up in City Hall

Leiden physicists Alexandre Morin and Samadarshi Maity study self-organisation and flocking phenomena. They shed light on flocking, which helps to understand how it is possible that birds in a flock don't collide. With plastic microbeads, they create an experimental setup and they developed a mathematical…

Investigating the intercultural connections that shaped practices of knowledge production in colonial Dutch Brazil.

Educators in European science museums sometimes think rather differently about the definition of an 'authentic' object. They think carefully about how they present those objects to teach visitors something or make them curious. This was shown in research by the Science Communication & Society department.…
