The NeIC conferences are organised biannually bringing together around 230 experts, researchers, policy makers, funders and national eIntrastructure providers from the Nordics and beyond. The aim is to create an opportunity for people in the eInfrastructure field to connect and collaborate with colleagues across the Nordics and to enable them to share knowledge and expertise. The title for this year’s event is ‘Nordic Infrastructure for Open Science’. We will take a closer look at how we can collaborate across borders to strengthen the field of Open Science. During the three days of the conference we will show examples of Open Science collaborations taking place in the Nordic region, as well as connect what is happening in the Nordics to a larger, international context – in particular the European Open Science Cloud.
