In the context of the WP5 “Training and capacity building for key national and international stakeholders”, a key activity is to unlock the expertise in handling cancer related data both within and outside of the EOSC4Cancer consortium, and bundle this in such a way that all researchers that are in need of training and support will be able to receive it. To this end, we aim to bring together a network of key cancer data support professionals, coming from within the respective RIs, relevant national initiatives and competency centers. These slides were used in the context of a 1-hour webinar on Monday, June 19th at 12:00-13:00 CEST, where we discussed with all relevant stakeholders both within the EOSC4Cancer project (representatives of all EOSC4Cancer partners across all WPs) and beyond (notably the Cancer Landscape Partnering Group and the Stakeholder Forum); A short overview of WP5 which aims to ensure that the biomedical researchers and healthcare professionals will have the knowledge and skills on how to best address their scientific questions and challenges by using the tools and infrastructure towards accelerating and optimising their research. Foreseen scope and membership of the network, including the potential activities envisioned throughout the lifecycle of EOSC4Cancer and beyond. Discuss ways of contributing to the network, aligned to your ongoing activities within EOSC4Cancer.
