How can citizen science be used to communicate and provide data for social network analysis?

Citizen science has recently become a widely used term, but what does it mean exactly? How does citizen science compare to crowdsourcing? And where does community archaeology stand in this discussion?

Bringing science, technology and innovation to places that normally do not have access to these areas of knowledge. This is the goal of the first Open Science Hub in Portugal, founded in 2017 in collaboration with Leiden University. The hub is managed by assistant professor of astronomy and society…

The new open access book The Science of Citizen Science bundles insights into science that is conducted together with citizens, to promote this growing form of science.

Although science and education have top priority, exploratory projects with companies, governments and NGOs generate ample opportunities in terms of societal challenges, science strategy, valorisation and research collaboration. In the LIACS Applied Data Science Lab, our master's students and graduates…

Each group has a small whiteboard. The frontal projection point has a short-throw projector with motion tracking and live annotation.…

Research in the Daniela Kraft Lab focuses on self-assembly in biological and soft matter systems, ranging from anisotropic colloidal particles to lipid membranes, emulsions, and viruses.

Shared, general-purpose labs.

Mapping out the problem of plastic pollution requires a lot of data over a large area. That's why scientists are increasingly turning to volunteers for help, also known as citizen science. But what are the challenges for a researcher when he or she involves the public in research in this way? Four Leiden…

This year will see the start of not one but two citizen science projects in Leiden and The Hague. This is the outcome of a large survey among residents and researchers in both university cities. The Citizen Science Lab will help the winners implement their ideas, with support from the University and…

We investigate the physics and design of mechanical metamaterial, intricately sculpted materials with properties set by their architecture.

In the Brain and Education Lab we study the development of complex cognitive processes involved in skills such as learning, reading and math.

Psycho-physiological reactions to stress.

Measurement of brain activity by external electrodes (EEG).

Reactions and reaction times in cognitive tasks.

We study cell-fate decision-making using embryonic stem cells as a model system. Stem cells integrate a large number of cues to direct their development into a great variety of cell types.

The Navigation Lab Leiden is part of the department of Health, Medical and Neuropsychology at Leiden University, and led by Ineke van der Ham We study human spatial cognition, with an emphasis on navigation ability. We examine factors that can explain for individual differences, such as gender and age.…

We focus on natural products research, traditional medicine, ethnobotany and phytochemistry.

Chromatin is an ubiquitous protein-DNA complex that forms the structural basis of DNA condensation in all eukaryotic organisms.

Neurobiological, cognitive and behavioural measurements of normal and abnormal child development.

Petra van der Bekerom, Joris van der Voet, and Johan Christensen, three assistant professors at Leiden University, conducted a large-scale survey experiment about whether citizens are more negative about failing service delivery than private organizations.
