What is Open Science?

Empirical disciplines have been experiencing ongoing methodological reorientation toward more transparency and open research practices. As a consequence, a series of methods were proposed to increase scientific integrity. Open science practices include preregistration, replication research, publishing open access, and sharing data, research material and code.

In 2021 the 193 UNESCO Member states defined Open Science as a global movement that aims to “make scientific knowledge openly available, accessible and reusable for everyone, to increase scientific collaborations and sharing of information for the benefits of science and society, and to open the processes of scientific knowledge creation, evaluation and communication to societal actors beyond the traditional scientific community.” 

Open Science Community Amsterdam

The Open Science Community Amsterdam is part of the larger open science community network in the Netherlands. It encompasses the three big educational institutions in Amsterdam, the UvA, the VU and the HvA as well as the Student Initiative for Open Science (SIOS). Open science communities are an initiative to create a platform for researchers and students from all faculties and academic levels to subscribe to the open science philosophy, talk and learn about open science practices, and get concrete advice and help on how to apply them in their research projects. The Open Science Community Amsterdam is organizing events, both in-person and online. To receive a monthly overview of activities organized by OSCA, subscribe to our Newsletter.

OSCA Board

Alexandra Sarafoglou

University of Amsterdam
Social and Behavioural Science
Department of Psychology

I am a postdoctoral fellow at the department of Psychological Methods at the University of Amsterdam. Together with Suzanne Hoogeveen, I founded the Open Science Community Amsterdam. During my PhD, I studied open science related research methods with a particular focus on analysis blinding and preregistration. My research interests include Bayesian inference, and meta-scientific research.


Bert Bakker

Bert Bakker is an associate professor at the Amsterdam School of Communication Research (ASCoR, UvA) and his position focuses on fostering “good research practices”. In his role Bert serves as the open science coordinator of ASCoR advising colleagues and students how to make their research more transparent. Bert’s substantive research interests focus on the question how citizens form their beliefs about politics. His research has been supported by a Marie Curie Global Fellowship, Investment Grant from the NWO, and more recently, a VIDI grant. When it comes to teaching, Bert teaches courses on experimental methods and transparent research practices in the research master communication science. As a board member Bert would like to deepen and broaden the role of the Open Science Community at the University of Amsterdam.


Eduarda Centeno

VUmc / Université de Bordeaux
Research Assistant / PhD Student

Institute of Neurodegenerative Diseases

I’m doing a Ph.D. in Neuroscience at the Université de Bordeaux (France). In parallel, I work as a Research Assistant for the MULTINET lab at the VUmc in Amsterdam. My primary focus is implementing OS tools and best practices in both scenarios. Moreover, we recently recreated an OS working group at A&N to enhance our department’s use of OS best practices.


Gerben ter Riet

Amsterdam University of Applied Sciences / Amsterdam University Medical Center
Faculty: Health
Senior methodologist

As a methodologist with a background in epidemiology, my prime affinity is with transparency in doing research. That implies preregistration of protocols and analysis plans, and data and code when possible. Reducing research waste is important too. Relevant questions, good study design, valid (data) analysis and honest reporting. Giving researchers more recognition and reward for these activities is crucial. More reflection, slow(er) science, less is more, quality over quantity. Together with 6 colleagues, at the Urban Vitality Open Science Support Desk, I support around 100 applied researchers with a team of information specialists, datasteward, privacy officer and a qualitative and quantitative methodologist.

Niels Reijner

Amsterdam UMC/VUmc
PhD student
Anatomy and Neurosciences
Clinical neuranatomy and biobanking (CNAB)

I am a PhD student at the Amsterdam UMC location VUmc in the department of anatomy and neurosciences. My focus is on Alzheimer’s Disease which I study in human post mortem MRI scans and brain tissue. Additionally, I assist in the processing of brain donors working for the normal aging brain collective (NABCA) and additionally in collaboration with the Netherlands brain bank (NBB).


Ewa Miedzobrodzka

Vrije Universiteit Amsterdam
Postdoctoral Researcher
Behavioural and Movement Sciences,
Dept. of Clinical Developmental Psychology

I’m a media psychologist, researching media violence (violent video games) effects on adolescents’ social skills. In my research, I apply behavioural and neuroimaging approaches, and use open science practices such as preregistration, data, and analyses code sharing. My OS topics of interest are: transparent and reproducible pre-processing of (neuroimaging) data, use of secondary datasets and data banks, especially for media psychology and neuroimaging research.


Leonhard Volz

University of Amsterdam
Social and Behavioural Science
Department of Psychology
Research Assistant

I am a passionate advocate for open science in student research and represent the Student Initiative for Open Science in the OSCA Board. Next to SIOS, I have been active in various other topical (student) initiatives, such as JEPS, SOSIP, and the Psychological Science Accelerator. Besides open science advocacy, I am a Research Master student at the University of Amsterdam with a focus on psychological methods, statistics, and computational methods. There, I work on different approaches to psychological modelling, such as network analysis, investigating mathematical models, and broader formal modelling approaches.


Contact us

During our consulting times we provide researchers with advice on the preregistration of experiments, data storage and sharing, and workflow.  We are open to students and researchers at all levels.

Our office is located at Roeterseiland Campus of the University of Amsterdam, building G, room REC-G 0.30. We recommend researchers who would like to receive advice to make an appointment with us ahead of time via openscience.amsterdam@gmail.com.
