• Interdependent infrastructure networks are investigated through network-flow, inoperability IO models, and empirical interdependency analyses to characterize cascading disruptions across sectors. [3] [1] [19] [6] [8]

• Resilience as a central design and assessment goal, with frameworks to quantify seismic resilience, system robustness, and preparedness for large-scale disruptions in critical infrastructure. [4] [2] [20] [18]

• Vulnerability analysis and risk management for transportation and urban networks using vulnerability metrics, accessibility methods, and road-network risk evaluation. [9] [10] [5] [16]

• Decision-making under uncertainty and resilience-focused risk management, including framework for resilient maritime/infrastructure decisions and crisis management considerations. [17] [20] [18] [19]
