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.

Are you currently enrolled in an applied sciences programme and are you considering a university master? At Leiden University you are more than welcome. A master at University will provide more depth in knowledge and you are able to specialise in a great number of areas of expertise. With the right…

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

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.

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

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.

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.

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…

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?…

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

Mari Nakamura defended her thesis on 14 March 2017

This doctoral thesis comprises four studies on the content and structure of physics teachers’ belief systems about teaching and learning physics in secondary education in the Netherlands.

History lecturer Giles Scott-Smith is enthusiastic about the new pitch-to-peer programme (P2P), for which students have to make an original, creative assignment and evaluate one another’s work. This is part five in a series of articles about lecturers and innovation in teaching and learning.

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

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.

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.

This dissertation aims to establish a dialogue between ethnomusicology (more specifically indigenous organology), the anthropology of art and the culture of the Apinaye peoples, in order to understand how the musical objects of these peoples are learned and taught, and thus to understand its musical…

The focus of the Bachelor Data Science & Artificial Intelligence is on computer science, and its applications in Artificial Intelligence. You will receive a strong basis in mathematics, statistics and computer science, combined with advanced knowledge of machine learning, cognitive science, human-robot…

This thesis reports on a study that examined the development of L1 teachers’ practical knowledge when they researched and implemented concept-context rich education in an action-research setting.

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.
