We perform multidisciplinary research at molecular, cellular, and organismal levels of animal biology to increase fundamental understanding of health and disease.

We perform multidisciplinary research at molecular, cellular, and organismal levels of animal biology to increase fundamental understanding of health and disease.

Animal Sciences’ contributions to the Development & Disease research theme include the mechanisms and evolution of embryonic development, the development of cognitive mechanisms, and animal models for understanding mechanisms of human disease.

Animal Sciences’ contributions to the Evolution & Biodiversity research theme include evo-devo research, the evolution of cognitive and behavioural traits, and the evolutionary mechanisms of stress adaptation. This research involves both indoor and outdoor studies.

Anthropogenic noise negatively affects wildlife in a wide range of taxonomic groups.

To what extent is sound a stressor to fish? And are behavioural and physiological phenotypes equally sensitive to disturbance by noise pollution?

NMR theory can be tough. Luckily, most NMR theory can be visualized to aid you in understanding. The animations below show precession with a 180 degree pulse, J-coupling and T1/T2 relaxation.

All biological and bio-medical research carried out at Leiden University is subject to strict conditions.

What does the interspecies interpretation of the equality principle mean for the liberal democracy, and is it possible to provide for an appropriate legal and political position for animals without defying the classic-liberal principles of the liberal democratic state?

This thesis aims at thinking through the ethical position of animals in a way that differs radically from the manner in which this ethical position is thought within contemporary animal rights discourse.

Main challenges in skin vaccination are overcoming the stratum corneum (SC) barrier and targeting the antigen presenting cells (APC) in the epidermis and the dermis.

We are developing the conceptual framework, which is new to this taxonomic group, and evaluate the current state of the art with respect to all critical parameters and transfer functions for a fully developed Population Consequences of Acoustic Disturbance (PCAD) model.

This part entails the analysis of an extensive sample of animal bone (c. 30,000 pieces) retrieved from well-defined archaeological contexts of the early period at Tell Sabi Abyad, c. 6800-6200 BC. It comprises aspects of taphonomy, ageing and osteometry, the reconstruction of the local spectrum of domestic…

Birds sing to be heard, but how do they cope with increasing noise levels? Which species persist in cities and why? And do they thrive or suffer in the urban soundscape?

Brendan Carroll promoted On Thursday October 30th Brendan Carroll successfully defended his PhD dissertation entitled:

Keeping and breeding of test animals for the purpose of scientific research and education.

Animal Sciences’ contribution to the Bioactive Molecules research theme includes research on molecules from natural sources, such as plants, insects, and snake venom, with the aim to identify novel anti-cancer, anti-inflammatory, anti-microbial, and anti-diabetic agents.

Did early farmers deliberately use animal manure on their fields?

The eighth issue of the JLGC explores the diverse and interdisciplinary research on our multifaceted relationship with animals which is currently taking place, re-examining the relationship between humans and animals, and the definitions involved.

On 10 October 2019, Janneke Vink defended her thesis 'The Open Society and Its Animals'. The doctoral research was supervised by Prof. P.B. Cliteur.

Sarah Giest, Assistant Professor at Leiden University, and Ishani Mukherjee researched the topic of 'Behavioural Insights Teams (BITs) and Policy Change: An Exploration of Impact, Location, and Temporality of Policy Advice'.

Can animal venoms yield novel antimicrobial peptides?

Animal Sciences’ contributions to the Host-Microbe Interactions research theme focus on the interaction of animal hosts with pathogenic microbes but also the beneficial role of the gut microbiome.

Some MPs are very active, while others are not. The number of proposals and questions that MPs in the Netherlands put forward is determined in part by the level of activity of their fellow committee members rather than by electoral incentive, which is the case in other countries.

There are five institutes at the Faculty of Social and Behavioural Sciences:

We are very happy to welcome you to spend a semester or year studying with us at the Faculty of Social and Behavioural Sciences. This website will provide you per programme with information on your course schedules and much more.

This ecological community has long been known to affect host biology, and their diverse roles have been further clarified in recent years following numerous studies of animal:microbiota interactions in diverse systems.

In 2021, the National Cyber Security Centre (NCSC) asked Leiden University to conduct a rapid review of best practices and possibilities for follow-up research on the integration of behavioral sciences in security by design methodologies and projects. This academic field is called security by behavioral…

Mari Nakamura defended her thesis on 14 March 2017

If male budgerigars can successfully open a puzzle box with food, they become more attractive to females. Biologist Carel ten Cate and Chinese colleagues published experimental evidence for this in a paper in Science on 11 January. Various Dutch and international media wrote about the paper.

My artistic practice deals with documents and, more specifically, with the use and the exploration of their narrative potential.

The Faculty of Social and Behavioural Sciences brings together high-quality research and outstanding teaching in the disciplines of cultural anthropology, education and child studies, political science, psychology, science and technology studies, as well as in multidisciplinary approaches.

Who is Economic Man? Every economic paradigm presupposes an anthropology, a theory of human nature. This project explores the anthropologies presupposed and produced by ancient Greek economic texts, and the specific knowledge forms that shape these anthropologies.

Research in Leiden University’s Institute of Political Science focuses on the dynamics and the interaction of political institutions, individual decision-making, and collective behaviour.

Appropriate animal models for intradermal vaccine delivery are scarce. Given the high similarity of their skin anatomy to that of humans, minipigs may be a suitable model for dermal vaccine delivery.

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…

The more opportunities a child has to learn and develop, the stronger his or her future position in society. Leiden University investigates how the brain picks up information, and how learning processes can be influenced positively.

By training with virtual opponents known as computer generated forces (CGFs), trainee fighter pilots can build the experience necessary for air combat operations, at a fraction of the cost of training with real aircraft.
