Unit created in January 2021, as a unit supervised by the R+D+i Office of the Fundación para la Investigación Biomédica del Hospital Universitario Ramón y Cajal, the management body of the IRYCIS, with the main mission of extracting knowledge from both structured and unstructured information, by establishing homogeneous criteria for registration, digitization and protection of clinical data for research at the IRYCIS, as well as the management and exploitation of this information to establish and consolidate a transversal line of research related to data mining, artificial intelligence and process mining in the big data environment. It is also the mission of its coordinator to supervise and coordinate actions in the field of data protection, exercising the role of Data Protection Officer of the FIBioHRC.
