As part of the 2025 Joint General Assembly in London, the coordinators of three Horizon Europe consortia, OSIRIS, TIER2, and iRISE, came together for a collective interview to reflect on their shared achievements, project synergies, and emerging priorities for strengthening reproducibility across European research systems.

Collaboration enables the three projects to align protocols, compare methods, exchange knowledge, and jointly address challenges, producing stronger, more coherent outcomes. An example is the joint scoping review by OSIRIS and TIER2, which now underpins multiple partnership outputs and informed iRISE’s SOLES platform, supporting machine-learning applications and an interactive evidence resource for the broader community.

Additionally, Tony Ross-Hellauer offered a concise overview of TIER2’s key contributions and the benefits of the growing tri-consortium partnership in a dedicated video to the project. He highlighted TIER2’s eight Pilots, which are testing new interventions, tools, and practices that will support researchers, funders, and publishers. 

The collaboration with OSIRIS and iRISE has created significant synergies, enabling shared methodologies, interoperable outputs, and a unified approach to addressing system-level challenges. Joint efforts on evidence synthesis and interventions for publishers and funders have strengthened the quality and cohesion of the projects’ outputs.
