PhD candidates carry out a programme of independent research and additional limited) course work, culminating in production of a PhD thesis in typically 4 years.

The group is involved in training in areas of diagnostic skills, treatment/prevention/intervention, neuropsychological assessment, behavioral observations, clinical interviewing, knowledge of intellectual disability, autism, ADHD, psychosis and aggression.

If you wish to know exactly what is going on in a healthy or sick human body, and at various levels such as molecule, cell, tissue, organ, larger systems and a person as a whole? Do you wish to learn how to do research which contributes to diagnoses, treatment and prevention of diseases? Then the bachelor…

Historiography of science is in its current self-image a non-evaluative discipline. Its main goal is to understand past processes of knowledge formation on their own terms. In the last few decades this approach has greatly improved our understanding of the phenomenon of science. Yet, something strange…

Quantum Information Science & Technology (QIST) encompasses the understanding, design, construction and investigation of quantum information processing systems, such as quantum computers, quantum communication networks, and quantum sensors.

Perhaps you are completely new to the concept of Liberal Arts and Sciences, or perhaps you are familiar with the Liberal Arts colleges of the United States. So, what actually is Liberal Arts & Sciences, and why has it become so popular in the Netherlands in recent years?

The first photo of a black hole and measuring anxiety in the brain... From 13 until 22 May we're serving a free slice of science with your pizza.

Get to know us through our online and in-person events for prospective students!

What we did this year? Well, we ran for charity, moved a 2,000 kilo electron microscope and ate poffertjes in the garden. Oh yes, and together mapped out a strategy for the next five years. Warm up the fingers and get ready to scroll through the year of Leiden Science in 2023.

The group Clinical Neurodevelopmental Sciences has expertise in individual differences in child development, in particular the development of psychopathology, ranging from mild to severe neurodevelopmental disorders.

Our Talents and Discoveries is a yearly publication by the Faculty of Science of Leiden University, published since 2003. You can read all the editions online. Note that the original publication was in Dutch; the original title translates as 'What we are proud of'.

The Leiden Science Young Talent Award is awarded yearly to a student who completed their bachelor’s degree with an excellent thesis.

Microbial Sciences' contribution to the Evolution & Biodiversity research theme focuses on understanding how bacteria sense and respond to their environment, and how bacterial diversity and evolution is influenced by cooperative and antagonistic interactions taking place between microbes.

Microbial Sciences'contribution to the Development & Disease research theme is to perform world-class research to understand cellular morphogenesis, growth, development and virulence of microbes.

The Science, Management and Innovation (SMI) group examines organisational dynamics governing the management of complex R&D projects and technology commercialisation.

How to stimulate novel research in science and innovation

This thesis focuses on the social dimensions of crane and wetland conservation in rural landscapes in Kenya, Uganda and Zimbabwe.

The aim of the research programme is to provide insight into the cognitive processes and brain mechanisms that underlie reading, arithmetic and learning in general.

Computers are becoming so smart that in the future they will perhaps take over the role of judges. In the meantime, experts at Leiden University are examining the question of which standards responsible data science should meet.

Plant Sciences' contribution to the Bioactive Molecules research theme is to identify new plant bioactive molecules, and unravel their mechanisms of action in plant development or health, and the regulatory networks and (bio)synthetic pathways required for their production.

How do you involve a local community to tackle biodiversity loss? How do you create awareness and political movement on climate change? And how do you find a balance between environmental impacts and economic needs when it comes to pollution? These are examples of core questions at the heart of a new…

Cognitive processes of learning with a focus on reading comprehension and the development of mathematical skills.

The SAPPAO project aims to optimise the accuracy and reliability of predicting scheduled flight times. The full name of the project is 'A Systems Approach towards Data Mining and Prediction in Airlines Operations'.

The first day of the Online Well-being Week covered the topic of your mental health. And more specifically, how to not be too hard on yourself and how you might feel in these weird times.

In this PhD-thesis several new and existing data science application are described that are particularly focused on applications for tax administrations.

Living labs make it possible for citizens to participate in research for sustainable development of their environment. This way citizens, together with scientists and stakeholders, create local conditions for food production, healthy environment, and biodiversity.

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’ 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.

Mari Nakamura defended her thesis on 14 March 2017

FluidKnowledge will investigate the past, present and future of evaluating ocean science. Regarding the past, it will ask how research priorities in ocean science evolved until now. Which lines of inquiry became hot topics, and which died out? Who became global players, who ended up in the periphery?…

The nanoscale structure of a catalyst under reaction conditions determines its activity, selectivity, and stability. For the production of sustainable energy and materials, new catalysts are needed. By understanding the structure-activity relationships of catalysts under reaction conditions, insight…

Plant Sciences' contribution to the Evolution & Biodiversity research theme is to understand what are the key drivers of plant biodiversity during evolution with a focus on plant life history and resilience traits and develop tools to restore and maintain plant biodiversity.

Natural resources are becoming increasingly scarce. If we want to maintain our current standard of living, we will need inventive solutions. The researchers at the Institute of Environmental Sciences (CML) share their thoughts on how to achieve a fully circular economy in which as little use as possible…

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.

Microbial Sciences' contribution to the Bioactive Molecules research theme is to discover new bioactive molecules and enzymes and unravel their mechanisms of action, regulatory networks, and the (bio)synthetic pathways required for their production.
