What is an ELIXIR Node?
An ELIXIR Node is the collection of research institutes that work for ELIXIR in a single country. Each Node runs national services and supports local users, making Nodes the basic building blocks of ELIXIR's distributed structure. If you are looking for country-level life science data services, training, or support, the Node for your country is the entry point.
How a Node fits into ELIXIR
ELIXIR is described on its website as "Europe's distributed research infrastructure for life science data." That distribution happens through Nodes: rather than one central organisation delivering everything, each participating country contributes through its own Node.
A Node is not a single institute. It is a collection of research institutes within a country that jointly carry out ELIXIR work. This means the services you use may come from different organisations in the same country, all coordinated under that national Node.
What Nodes actually do
According to the ELIXIR website, Node institutes:
- Run national services — the data resources, tools, and infrastructure that ELIXIR offers in that country
- Support local users — life scientists, trainers, and others who need help using ELIXIR resources
This local support role is important: it means you can often get guidance in your own country rather than navigating the whole European infrastructure alone.
Nodes and the wider ELIXIR structure
Nodes are one part of how ELIXIR organises its work. The website lists several connected structures:
| Structure | What it is |
|---|---|
| ELIXIR Nodes | Country-level collections of research institutes running national services and supporting local users |
| ELIXIR Platforms | Networks of technical experts from across Nodes coordinating technical activities |
| ELIXIR Communities | Experts developing ELIXIR's vision and coordinating activities in key life science areas |
| ELIXIR Focus Groups | Time-limited groups addressing topics of emerging interest |
So Platforms, Communities, and Focus Groups draw their experts from across the Nodes — the Nodes supply the people and services that these other structures coordinate.
How to find your Node
The ELIXIR website has an "Explore our Nodes" section where you can browse Nodes by country. If you want to know which institutes represent ELIXIR where you are, or what national services and support are available to you, that page is the place to start.
Who benefits from knowing about Nodes
- Life scientists — to find open science resources and local support
- Prospective members — to reach out about joining or collaborating
- Existing members — to get involved in open calls and activities
- Funders — to understand how ELIXIR's work is organised across countries
- EU projects — to connect with the right national partners
If your goal is to use ELIXIR services, collaborate, or understand how the infrastructure is governed, identifying the relevant Node is usually the first practical step.
