Ziqi Wang is an assistant professor in the Department of Civil and Environmental Engineering. His research focuses on analyzing and understanding the reliability, risk, and resilience of structures and critical infrastructures under hazards. He is interested in computational methods of structural reliability and uncertainty quantification, focusing on interpretable probabilistic analysis methods leveraging domain/problem-specific knowledge. He also develops probabilistic methods to analyze the regional impact of hazards by adapting theories/models from reliability, uncertainty quantification, and statistical physics.

Wang's research focuses on analyzing and understanding the reliability, risk, and resilience of structures and critical infrastructures under hazards. He is also interested in applying probabilistic methods to a broader field of science. Here are a few of the research areas Wang is currently working on:

Reliability and Uncertainty Quantification methods leveraging domain/problem-specific knowledge

The hypothesis is that an optimal (e.g., efficient, accurate, interpretable, scalable, general) computational method does not exist if a wide spectrum of problems is considered; the domain knowledge should be injected into the design of computational methods for a particular class of problems. 

Here are a few preliminary results, collaborated with Postdoctoral researchers Jianhua Xian and Jungho Kim : 

Probabilistic approaches for analyzing the regional-scale impact of earthquakes 

  • Statistical physics and information-theoretic approaches in modeling and analyzing the collective behaviors of networked structures under earthquakes. This is an ongoing PhD research project for Xiaolei Chu and Sebin Oh. 
  • System-level seismic analysis of highway networks, as part of the Caltrans-PEER project "Prioritizing Regional Needs for Recovery Bridges through Post-earthquake Corridor Identification and System Fragility Assessment of the SF Region." z_wang.pdf (berkeley.edu)

Other research activities related to probabilistic methods 

  • Entropy-based metric for the impact of COVID. 
  • Modeling interactions of the psychological and physical responses to COVID to analyze the potential polarization of the collective psychological state of individuals. 

Here are a few preliminary results, collaborated with Marco Broccardo, Arnaud Mignan, and Didier Sornette:
