Next-Generation Data-to-Knowledge Computational Methods DATAKOM
The Next-Generation Data-to-Knowledge Computational Methods (DATAKOM) group generates high-impact research in data compression, bioinformatics, deep learning and multimodal forensics. Our work addresses critical societal and technological challenges by transforming next-generation data into actionable knowledge, following the classical data -> information -> knowledge paradigm. This knowledge enables disruptive innovation and tangible societal benefits.
Our research directly contributes to the societal challenge Security, Digital Transformation and Public Services, with a primary focus on Digital Transformation. The activities reinforce European innovation capacity through work in artificial intelligence, advanced computing, mathematical modelling, space and Earth observation, and cybersecurity and technological sovereignty. Our work aligns closely with the EU strategic priorities for a digitally empowered and secure society. Additionally, we also help address the challenge Knowledge and Quality of Life, specifically to the objective of promoting population health through biomedical research and the development of new therapies, achieved through our research in bioinformatics, particularly in microbial genomics, enabling the development of new antimicrobial agents.
