Which traits did change due to the invasion process of plants and how do these traits contribute to the invasiveness of such species. What is the role of carbohydrate accumulation? What is the function of carbohydrate accumulation in plants? Is genetic variation depleted in invasive species under se…

Growth hormone profiles are pulsatile and highly variable between individuals, limiting the implementation of mathemathical models to quantify an individual's secretion.

In a podcast episode of 'New Books in History' Claire Weeda talks about her book 'Ethnicity in Medieval Europe 950-1250: Medicine, Power and Religion'.

My PhD thesis investigates the ecological significance of resistance against drought-induced air bubble formation inside the water conduits of plants (embolism), and the plasticity and functional aspects of stem anatomical traits in woody and herbaceous species.

An investigation into how racial stereotypes were created and used in the European Middle Ages.

This research team is concerned with the measurement and modelling of behaviour, cognition, and unobserved traits (e.g., latent variables, missing data). Central aims include the distillation of a complex set of features into lower-dimensional representations (e.g., factor analysis, IRT), determining…

One of the main research focuses of the Hortus botanicus Leiden is to study how the current biodiversity we see today, has originated, changed, and developed over time. The Hortus wants to study the relationship between species in specific focal taxa and see how they have diverged over time.

On Thursday, 17 September 2015, the latest project of the Leiden International Humanitarian Law Clinic (the IHL Clinic) on ‘Principles of International Humanitarian Law applied to Cyber Warfare’ was concluded and presented to the Netherlands Red Cross.

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.

Using an interdisciplinary experimental approach grounded in behavioral economics and personality psychology, we identify an antisocial personality profile and examine its role across strategic contexts.

With cancer, a person’s body cells grow uncontrollably. Putting together a detailed picture of how this comes about makes it possible to develop efficient therapies. Researchers at the Leiden University Medical Centre (LUMC) and Leiden University are working together to gain a better understanding…

In this thesis, mathematical modeling and simulation was applied as a tool to inform quantitative decision making in oncology drug discovery and development.

A new app provides dynamic predictions of survival for patients suffering from soft tissue sarcoma. It was developed by the mathematical Institute research group DASPO, Data Analysis and Survival for Personalised Oncology.

Vocal learning is a trait shared by songbirds and humans. It is also a trait that is restricted by the brain rather than by a species' vocal apparatus. In this dissertation, functional MRI is employed in both species in order to explore potential common neural mechanisms underlying the ability to develop…

Plant-microbe interaction resulted in different physio/chemical responses by host plant and interacting rhizobacteria.

The study of orchid flowers, fruits, and inflorescences is crucial due to the remarkable diversity of orchid species and their unique adaptations to pollinators and seed dispersers. However, our understanding of the evolution and development of these organs within the orchid family remains limited.

This article examines the consequences of stereotypical beliefs regarding gender, traits, and leadership styles for manager preferences.

This dissertation examines what network in the human brain is involved in the perception of prosody and whether activity within this network is modulated by the personality trait alexithymia.

Our mission is to improve the description, prediction, understanding and the prevention and treatment of mood disorders, including unipolar and bipolar depression, as well as suicidal thoughts, feelings, and behaviors. To tackle this ambitious mission, we focus on several research streams.

The discussion on employability of higher education graduates has been around for several years, with more emphasis in the 21st century. Yet, universities are still challenged in the pursuit of providing work-ready graduates who can meet industry expectations.

My ERC Starting Grant, funded with €1.5 million for 5 years as part of the Horizon 2020 research and innovation program, is focused on building the early warning system WARN-D to reliably forecast depression in young adults before it occurs. Why depression, and why prediction?

Do young people who want to change gender have the unconditional right to medical treatment? Pediatric Endocrinologist Martine de Vries, who is also Professor of Medical Ethics, treats transgender children and adolescents. She will discuss this in her ‘Pride Talk’ on 18 September.
