Hjerde, Erik
Research scientist, Molecular Biosystems and Bioinformatics, Norstruct
Job description
Assoiated with the european ELIXIR project. In Norway, the project is coordinated by the University of Bergen and includes the Universities in Oslo, Trondheim, Tromsø and Ås. On a national level we aim to:
- to build a Norwegian Node in the pan-European research infrastructure ELIXIR (www.elixir-europe.org), with the Node delivering services and resources to the international community through ELIXIR on selected areas;
- to continue a National help desk serving users a broader set of services and assistance; and
- to provide an e-infrastructure allowing users to efficiently and safely store, share, analyse and publish their genomics scale data.
