ReproducibiliTea 23 May 2-3 pm CET: Scientific Red Teams  

Leo Tiokhin, from Eindhoven University of Technology will discuss with us the concept of Red Teams and how they can be used in research. 

Scientific Red Teams

Red teams are groups of individuals who play the role of an adversary – attacking a system and revealing its weaknesses, with the ultimate goal of improving system functioning. In the last two years, our group has attempted to incorporate the concept of red teaming into scientific practice. We have conducted a range of projects in which diverse teams of independent scientists have received financial compensation to criticize scientific research. In this session, I will summarize our experiences implementing red teams in science and outline directions for future development. My goal is to stimulate a discussion about the costs and benefits of red teams, and the potential role of red teams in the future of scientific practice.

Like two weeks ago, we will offer a hybrid session again. If you want to meet in person, please stop by the Bouman building (Room B.128). Others are welcome to join via Google Meet (link below).

Open call for the Open Research Award 2022

We invite you to submit your case study now! 

The University of Groningen Library (UB) and the Open Science Community Groningen launch the 3rd annual Open Research Award. The award celebrates the many ways in which academics make their research more accessible, transparent or reproducible.

600 words on your success or failure to use ‘open’ research practices.

Via this submission form

Now, up until September 30!

We welcome the submission of no more than 600 words in length that discuss the use of one or more open practices in the conduct of research and/or communication of outputs to achieve specific research aims or solve particular problems.

The case studies ideally explore the challenges of making open choices as well as those that celebrate positive experiences and successful open science practices.  Staff members and students can submit case studies. All submissions will be screened for eligibility by a jury. All eligible cases receive an Open Research Award certificate. In addition, three eligible cases will be randomly drawn by the jury; each of which will receive 500 euros. For more information check the webpage or contact us via

ReproducibiliTea, March 28, 2 pm: Federico Pianzola on “Open Science for the Humanities”

We are very happy to announce next week’s session with guest speaker Federico Pianzola. Based on his 10+ years experience as managing editor of an Open Access journal about literary studies and on his work with computational methods for cultural heritage data, Federico will present some reflections on strategies for promoting Open Science among humanities researchers.

It will be a hybrid session. If you want to meet in person, please stop by the Bouman building (Room B.128). Others are welcome to join via Google Meet (email us for the url).

ReproducibiliTea –  Timothy Errington on the challenges in the Reproducibility project: Cancer Biology

In 2013 a group of researchers started the Reproducibility Project: Cancer biology, with the ambition to replicate a total of 193 experiments from 53 high-impact papers. After seven years, because of a multitude of obstacles they encountered, they were only able to repeat 50 experiments from 23 papers. In our next session one of these researchers will be our guest. Timothy Errington will discuss with us the (un)foreseen challenges in this major project and we are honored to have him. We will be talking about things that are at the core of reproducibility, so don’t miss out!

2022 01 31 ReproducibiliTea – the University of Groningen Open Science Program

Dear all,

You are warmly invited to next week’s ReproducibiliTea meeting. We are happy to welcome Vera Heininga as our guest speaker!

Vera  is program leader of the UG-wide Open Science Program, which kicked off in September 2021.The aim of this two-year program is to stimulate and integrate Open Science into the research and education culture of the University of Groningen. The program has five pillars: Open Access, FAIR Data and Software, Open Education and Public Engagement and Communication. Vera will introduce the program, and as always in our ReproTea meetings, there will be ample time for questions and discussion.

What: Vera Heijninga on the University of Groningen Open Science Program

OSCG-Groningen Reprohack 11 November 13.00-17.00

Attention for Reproduction and Reproducibility of research is becoming increasingly important in scientific research. Therefore we invite you to join us in the OSCG-Groningen Reprohack on 11 November from 13.00-17.00 CET.

What is a Reprohack?
In a Reprohack (Reproducibility-Hackathon), participants try to reproduce the research output of other researchers, who may be other participants of the Reprohack or other researchers whoe made their data and code publicly available. During this workshop, participants will go through a research article in groups and try to reproduce the results as listed in the article using the code and data belonging to the article. This will give insight into whether the research is sufficiently transparent, clear, and reproducible. At the end of the workshop, we share our experiences and give feedback to authors to improve the reproducibility of their research.

There are two ways to participate:
1) As an author: You can test if your own research can be reproduced by others during the Reprohack. You will get feedback at the end of the event. You may decide to only provide your research or to participate in reproducing the work of others as well.
2) As an Reproducer: You can propose research to be reproduced that includes code and data to be used during the Reprohack. Or you can help in trying to reproduce the research of others attending the Reprohack. In this way, you can improve your skills and learn from each other to create reproducible research.

If you would like to participate, please fill in this form.

ReproducibiliTEA is back

ReproducibiliTEA will be back on Monday Sep 20th. For this first session of the new academic year, we are inviting all of you to brainstorm with us about the new topics for the upcoming sessions.

First, we are interested in what Open Science is for you. You are our main target population and we would like to gain more insight into your understanding and ideas of Open Science to better target our sessions to your needs. Second, we would like to brainstorm about themes for next sessions. What have you learned so far? What do you want to learn more about? Are there topics you need help with, you want to discuss with colleagues. Aspects you would like to evaluate more critically?

Everyone is welcome to join the discussion, from newcomers to old hands. It is possible to attend on campus (max 15 people). But you can attend online as well. More info here:

Online workshop 27 May 14:00-15:00: The Future is Open!

The future is open! 
How Open Science Communities can help transition towards Open Science as the future modus operandi

Join our online workshop 27 May 14:00-15:00 CEST: ‘The future is open! How Open Science Communities can help transition towards Open Science as the future modus operandi’ by Vera Heininga

In this talk, Vera Heininga will first discuss what she understands by Open Science (what is it, but also above all: what is it not?). Then she will discuss Open Science Communities (OSCs), what it entails exactly and how OSCs in the Netherlands can help / support researchers in the transition to Open Science. For the latter, she will draw on a recent article that was recently accepted by the journal “Science and Public Policy” (see the preprint here:

Vera Heininga is the Open Science coordinator of the University of Groningen. She is a great fan of Open Science, meaning that she: loves research transparency; pre-registers her confirmatory analyzes a priori; uses Open Workflow Tools (e.g., R Markdown); publishes in Open Access journals; and makes her well-annotated programming code publicly available. Vera is also an interdisciplinary postdoc at the Faculty of Behavioral and Social Sciences of the University of Groningen, and co-founder of the Open Science Community Groningen (OSCG).

For whom: Students, researchers, policy makers, support staff
