Wenjuan Sun is a Research Associate in Civil Engineering, Center of Advanced Technology for Large Structural Systems (ATLSS) at Lehigh University. Previously, she received her Ph.D. degree in Civil Engineering from Virginia Tech, with a M.Sc. degree in Geotechnical Engineering and a B.Sc. degree in Civil Engineering from Shanghai Jiao Tong University at Shanghai, China. Sun has a unique interdisciplinary background that encompasses traditional topics of civil engineering, probabilistic risk and resilience assessment, multiscale and multi-physics modeling and experimentation of civil engineering materials, and geoenvironmental impact assessment and sustainable construction techniques. Her research mainly focuses on developing computational models to solve engineering problems for supporting sustainable and resilient transportation infrastructures.

At the system-level, Sun has been developing mechanistic computational models to evaluate system resilience and evaluate different types of infrastructure interdependencies in a probabilistic manner. Her research findings in this area can provide informative suggestions to decision-makers for developing effective plans of retrofit, mitigation, and restoration. In particular, her work contributes to a comprehensive simulator - PRAISys (Probabilistic Resilience Assessment of Interdependent Systems) for post-disaster resilience assessments, with the implementation of mechanistic interdependency modeling while considering uncertainties.

At the component-level, Sun has developed computational programs to characterize material genome of infrastructure materials by measuring surface morphological characteristics and developing mechanical models. Based on the characterization results, she has established multi-physics models of infrastructure materials to build a mechanistic understanding of non-linear mechanical performances at different spatial scales, with experimental validations.
