The Advanced Computing, Data Science and Artificial Intelligence Support Unit (CDAI), led by Dr Andrés Henao, brings together a diverse team of computer science, data engineering, machine learning, and materials science. The unit establishes data and AI as the fourth pillar of scientific discovery at ICN2. They partner across the institute to deploy robust, bottom-up "FAIR-by-design" data pipelines, high-performance computing (HPC) environments and support everyday workflows from administrative staff to researchers.
