Bridge2AI Network for AI Health Science

Funds a network of centers that builds the methods to judge whether biomedical AI can actually be trusted.

Bridge2AI's first stage produced large, open, AI-ready biomedical datasets and best practices the research community could adopt. Having the data was step one; knowing whether what gets built on it can be trusted is the harder, unfinished part.

Stage 2 works on two fronts. One uses the Stage 1 datasets to go after biomedical and behavioral research grand challenges, new biological theories, and a

A network of 3-5 multidisciplinary centers advancing the science of AI science for Stage 2 of the Bridge2AI program, evaluating AI models built elsewhere in the program, producing best practices and evaluation frameworks for trustworthy, reproducible and explainable AI-enabled biomedical and behavioral research, and training the workforce — the grant-funded half of Stage 2's two initiatives, alongside a separate research contract.
