CERN's VRE (Virtual Research Environment) is an analysis facility that allows users to use a distributed data lake infrastructure (RUCIO) together with a distributed software service (CVMFS) to run their scripts and workflows on a reproducibility-oriented scientific analysis platform (REANA). Having the right middleware in place would simplify the use of these services by scientific users, allowing them to focus on their scientific projects instead of dealing with increasingly complex IT infrastructures. In this project, we will develop a JupyterLab extension that connects the REANA-VRE instance with the VRE Jupyter frontend through the REANA API. The extension would allow connecting to the user's REANA account, displaying their workflows as well as retrieving, interacting and bringing to the Jupyter frontend file system the data and results of the different REANA workflows..
