Wenjuan SUN, Ph.D., E.I.T.
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, computational mechanics, risk and resilience assessment. 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 physics-based computational models to model different types of infrastructure interdependencies and predict possible system recoveries under different hazard scenarios. 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 the development of a comprehensive platform - PRAISys (Probabilistic Resilience Assessment of Interdependent Systems) for regional resilience assessment, with the implementation of mechanistic interdependency modeling while considering uncertainties.
At the component-level, Sun has developed computational programs to characterize construction materials and perform mechanical failure analyses. She has established multi-physics models to build a mechanistic understanding of non-linear mechanical performances of construction materials and structures with experimental validations. She has also developed computational frameworks to evaluate the construction risk and the flood risk of different underground structures, such as tunnels and subway stations.
