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.
