Risk-Informed Resilience Frameworks for Infrastructure Systems

My research develops probabilistic, physics-informed frameworks that integrate field monitoring data, structural modeling, and decision theory to improve infrastructure safety and community resilience under natural and cascading hazards.

Research Themes
01

Seismic Risk & Critical Infrastructure Safety

Risk-informed assessment of critical infrastructure under evolving seismic hazard, with emphasis on probabilistic methods and decision support for nuclear and high-consequence facilities.

Key Directions
▸Time-dependent fragility and reliability of aging RC bridges under multi-hazard (seismic + scour + corrosion)
▸Post-earthquake monitoring decision frameworks using Value of Information and Bayesian updating
▸Nuclear facility seismic walkdowns and hazard-consistent ground motion development
▸Optimal monitoring strategies for condition assessment and recovery prioritization
02

Flood Resilience of Transportation Systems

Bridge scour, hydraulic loading, and resilience-based performance assessment for transportation infrastructure under extreme flood events and compound hazard scenarios.

12NCEE 2022EMI 2022
Key Directions
▸Flood fragility portfolios for transportation network resilience
▸Multi-hazard assessment integrating seismic and flood-induced scour for river-crossing bridges
▸Integrated bridge, transportation network, and community resilience frameworks
▸Validation of resilience frameworks using historical flooding events (Nebraska 2019 floods)
03

Monitoring, Digital Twins & Lifecycle Decision-Making

Combining sensing, uncertainty quantification, and simulation to support infrastructure monitoring, reliability analysis, and lifecycle decision-making toward digital twin frameworks.

In preparation — Structural Safety
Key Directions
▸Value of Information-based optimal sensor placement for concrete bridges
▸Markov Chain Monte Carlo methods for structural state estimation
▸Digital twin fidelity and update strategies for agency adoption
▸Probabilistic health monitoring frameworks connecting data, uncertainty, and structural performance
