EURION Cluster Establishes Working Groups

28 Jan 2020

Since its start in January 2019, 13 working groups have been established in the EURION Cluster, each with a special thematic focus in accordance with the cluster mandate to optimize synergy and avoid overlaps between the projects. The working groups have leaders from all the eight sister projects in EURION as well as from the Joint Research Centre (JRC).

The working groups have initiated work on e.g. common activities such as the selection of chemicals being tested, data sharing and annual meetings. As regards the latter, the two sister projects GOLIATH and OBERON hold the chairmanship of the cluster for the first 15 months and subsequently, these two projects coordinated the annual cluster meeting held on 5 February 2020 in Paris. From 1 April 2020, the sister projects ENDpoiNTS and ERGO will hold the chairmanship.

The EURION cluster working groups are:

  • Adverse Outcome Pathways (AOPs);
  • Chemicals;
  • Animal studies: rodents;
  • Animal studies: aquatic organisms;
  • In vitro models;
  • Regulatory affairs and policy;
  • Integrated Approaches to Testing and Assessment (IATA);
  • In silico;
  • Omics;
  • Epidemiology;
  • Dissemination/communication;
  • Data management;
  • Pre-validation.

The AOP working group is chaired by ERGO and around 40 members representing the eight EURION projects have joined the group. The overall mission of the working group is to support and facilitate AOP-related activities and to bring together AOP-structured information and data across the EURION cluster. Both introductory and advanced training courses are being organised in 2020 to meet the needs of the cluster. In 2021, the first AOP development workshop will be organised and aligned with the annual cluster meeting, facilitating collaborative AOP development and entering of project data into the AOP-wiki.
