  • cBioPortal for Cancer Genomics

    Science and medicine

    The cBioPortal for Cancer Genomics is a resource designed to provide broad community access to cancer genomic data. It provides a unique user­-friendly and "biology­-centric computational user interface", with the goal of making genomic data more easily accessible to translational scientists, biologists, and clinicians. The interface was explicitly built and continues to evolve with careful usability studies involving multiple biological and clinical users, and an active and engaged user base.

  • MalariaGEN

    Science and medicineNew in 2026

    MalariaGEN is a global network of global partners who share and integrate data relevant to inform malaria surveillance, our mission is to generate insights and tools that bridge the gaps for analysts in malaria endemic settings to use their data meaningfully to inform public health efforts. We build and optimise data resources and analytical tools to run directly in the cloud. Our flagship project is the Vector Observatory, which includes whole-genome sequence data for over 30,000 mosquitoes, integrating data from 70 partners across the globe from over 17 different mosquito species -- this is the largest resource on genetic variation data for any multicellular organism (other than humans!). Our goal is to enable analysts, scientists, students and public health practitioners to access these data without the need for any dedicated compute infrastructure, by optimising our resources to run within free compute environments (a big shout to Google Colab!) and by developing training resources that support partners to get confident with using cloud-native data and resources for their analysis.

  • Open Technologies Alliance - GFOSS

    Science and medicine

    Open Technologies Alliance (GFOSS) is a non-profit organization, with 37 Universities and Research Centers as its shareholders. Our main goal is to promote Openness. GFOSS – Open Technologies Alliance is a platform for Open Standards, Free Software, Open Content, Open Data & Open Hardware in Greece. The major Greek Universities and Research Centers participate in GFOSS – Open Technologies Alliance, while leading members of the Greek community of developers play a key role in the implementation of our policies. Through our initiatives we aspire to contribute and coordinate the efforts of groups of volunteers, public servants, university researchers and students enabling them to form the backbone of Greek FOSS development and implementation. GFOSS is one of the strategic actors for the promotion of OSS throughout Greece (see https://joinup.ec.europa.eu/sites/default/files/inline-files/OSS%20Country%20Intelligence%20Report_GR.pdf ). Many public administrations and academic institutions collaborate with GFOSS to implement open source projects and through Google Summer of Code we give the opportunity to students to actively engage in the production and the actual implementation of an open source project. GFOSS also contributes and advises on the development of various open source projects related to e-government and digital transformation in Greece (e.g. https://howto.gov.gr/ - https://forma.gov.gr/) and actively promotes the use of Open Source software and hardware in the Greek primary and secondary education through the Open Educational Technologies Competition (https://openedtech.ellak.gr/ )
