Precision intervention, enabled by shared AI capabilities

Older adults with similar diagnoses can differ substantially in biology, function, behavior, environment, and response to intervention. The Stanford AITC develops shared AI and technology capabilities to support precision intervention development, testing, and implementation, helping investigators examine who may benefit, what intervention should be delivered, and when and how delivery should adapt.

Selected research directions


Research Directions

SU-AITC brings together complementary AI and technology approaches for precision interventions in aging and AD/ADRD.

These areas highlight ongoing and published work relevant to SU-AITC. Featured demos and projects will be added as the Center develops.

Foundation Models

AI foundation models for learning scalable representations from multimodal brain and health data.

Brain World Model (BWM)

A multimodal foundation model framework integrating biological, psychological, environmental, and physical health data to learn comprehensive representations of the human brain and enable more precise diagnosis and personalized care.

Digital Monitoring Tools

AI-enabled tools for monitoring mobility, behavior, function, and health in aging and AD/ADRD.
