This project focuses on economic resilience under disasters. It aims to estimate indirect economic losses, including business interruption (BI) and Secondary Indirect Losses caused by disasters, for instance, building damages, critical infrastructure disruptions and supply-chain disruptions, based on economic theories and interdisciplinary knowledge. During this process, the formation mechanism of indirect economic losses is identified, and a comprehensive framework for estimating indirect economic losses is proposed. This research will provide support for decision-making on economic losses mitigation and resilience improvement.

Methods on Modeling and Predicting Business Interruption Losses in Earthquake-Struck Regions
Predicting business interruption losses (BIL) could support the development of informed post-disaster recovery strategies and the decision-making of pre-disaster prevention and insurance.

Estimation of the Indirect Economic Impacts Caused by Transportation Infrastructure Disruptions
Transportation infrastructure system is critical to the economic development as well as the sustainability of urban cities. Transportation disruption can not only cause great direct economic losses, but also lead to huge indirect economic impacts.

Hybrid Modeling-Based Approach for Assessing and Enhancing Seismic Resilience of Healthcare Systems
Healthcare systems play an important role in the response and recovery of earthquake-hit regions. However, healthcare systems themselves likely subject to earthquake impacts, which hinders medical service continuity. The enhancement of resilience to earthquakes is crucial for healthcare systems to maintain their functionality during earthquakes and recover in a timely manner in the aftermath of earthquakes.

Human mobility under extreme weather events
Deep understanding of the complex patterns of urban human mobility during extreme weather events (EWEs) is of significant importance to the assessment of impacts of EWEs, maintenance of urban commuting conditions, and improvement of the overall disaster response capacities of the cities.

Indoor Crowd Evacuation Modeling and Simulation
Studying indoor crowd emergent evacuation is of great significance for ensuring human safety and reducing casualties. With the development of computer science, simulation of crowd evacuation in fire scenarios has become the main direction of current evacuation research.

Human Evacuation Behaviour in Building Emergency
Understanding human evacuation behaviour in building emergencies in-depth in aspects of is of great significance to simulate crowd evacuation, to optimize building design, to effectively intevene evacuation and effectively conduct fire evacuation training.

Social component in community health resilience to earthquake: Theoretical and empirical study
Community health resilience to earthquakes refers to the capacity of a community to prepare for, respond to, and recover from the impact of earthquakes so as to reduce mortality and morbidity of the local community. Technical infrastructure, hospitals, and residents are the key elements in community health resilience.

Infrastructure systems resilience
Critical infrastructure systems (CISs) are the building blocks of modern cities. Understanding the response and recovery mechanisms of interdependent CISs in the event of disaster is essential in order to assess the impact of disasters on the CISs and improve urban disaster management.
