CODECHECK is a collaboration project lead by Stephen Eglen and Daniel Nüst together with a community of codecheckers, collaborators in the scientific, academic publishing, and scholarly infrastructure communities, and a codecheckers team.


Stephen Eglen (Co-PI)

Stephen Eglen is a professor in Computational Neuroscience at the University of Cambridge. He has over 20 years experience as a researcher in Computational Neuroscience, and has worked on several projects encouraging more code and data sharing in Neuroscience. Most recently this led to a trial project with the journal Nature Neuroscience, and our guidelines for sharing in Neuroscience. Stephen is also a fellow of the Alan Turing Institute (ATI), based in the British Library, and a member of the International Neuroinformatics Coordinating Facility which will provide logistical support e.g. on supercompute infrastructure.

Stephen contributes his domain-specific expertise in computational neuroscience and Open Science.

Daniel Nüst (Co-PI)

Daniel Nüst is a postdoctoral researcher and research software engineer ith the Chair of Geoinformatics, TU Dresden, and at the Institute for Geoinformatics (ifgi), University of Münster. He develops tools for open and reproducible geoscientific research and is a proponent for open scholarship and reproducibility in the projects NFDI4Earth, Opening Reproducible Research (o2r), and OPTIMETA. He is also engaged in the Open Source and Open Science communities and has held workshops on Reproducible Research in geosciences, GIScience, and digital humanities.

Daniel contributes his technical expertise in reproducible research & scholarly communication infrastructures and geospatial data science.


The codecheckers team does the hard work of conducting CODECHECKs. Become a codechecker!

Reproducible AGILE Logo

The Reproducible AGILE initiative conducts reproducibility reviews as part of full paper peer review for the Association of Geographic Information Laboratories in Europe’s (AGILE) annual conference series. The reproducibility reviews fulfil the CODECHECK principles and therefore they are listed in the CODECHECK register. Be sure to check out their Guidelines for Authors and Reviewers.
