Research Pillars

Research activities in 5 interconnected “pillars”

MIDAS focuses on five pillars, described below, within its overall effort to support data science and Artificial Intelligence (AI) research. Across these pillars, MIDAS promotes responsible research practices, supports the adoption of new data types and methodologies, and facilitates convergence science. The pillars will change over time: current pillars will be retired or shift focus, and new pillars established. Furthermore, these pillars are interconnected where possible, to maximize the synergies between them and leverage the interdisciplinary MIDAS community and the collaborative spirit U-M is known for.

In addition to supporting research within the pillars, MIDAS fosters connections and collaborations in data science and AI for the entire University, maintains a large umbrella covering all relevant research areas, and supports an inclusive community of researchers. MIDAS also continues to promote cutting-edge methodological development as the foundation for data science and AI.
