LIUYUN XU

Welcome to XU (X in UQ) Lab at UT Arlington!

We pioneer computational, data-driven, and AI-enabled paradigms to advance uncertainty-aware assessment and decision-making for civil infrastructure and communities under extreme events.

In recent decades, urban built environments have experienced substantial infrastructure damage, economic losses, and societal disruptions due to extreme events (natural hazards). Enhancing resilience and adaptation under rare, high-impact events is essential.

To this end, we advance AI and computational approaches in (a) physics-based, (b) data-driven and (c) automated modeling. We further contribute to risk, reliability and resilience assessment by developing uncertainty quantification, probabilistic modeling, and digital twin techniques. The overarching objective is to support risk-informed decision-making for resilient infrastructure systems.

Our applications span structures, infrastructure and coastal communities under windstorms (hurricanes), floods, and earthquakes.
