Carnegie Mellon University's Digital Twin for Complex Engineering Systems Initiative is developing a new generation of trustworthy, adaptive Physics-AI Digital Twins for complex engineering and biomedical systems.

By fusing governing physical laws with scientific machine learning, artificial intelligence, and real-time data streams, researchers are moving beyond static, single-use digital twins. The initiative aims to create universal, transferable foundation models that continuously learn from multimodal data, quantify uncertainty, predict system behavior, and support real-time decision-making across diverse domains.
