Research Statement

Dr. Ou holds a Ph.D. in structural engineering from Purdue University, two bachelor’s degrees, one in civil engineering from the University of Sydney, Australia, and the other in the theoretical and applied mechanics from Harbin Institute of Technology, China.

Dr. Ou's research emphasis is the infrastructural system performance assessment under extreme natural and man-made disasters using experimental and real world data.  Advanced experimental techniques such as quasi-static testing, hybrid simulation, and shake table testing are of her interests. She has shown the improved of hybrid simulation fidelity with incorporating model updating for seismic analysis of structure with large nonlinearity. 

Her group is also actively exploring using real world information retrieved from the embedded sensor system in the infrastructure, or from mobile sensors such as UAVs and cell phones for structural health monitoring.  These data can be in the form of engineering measurement (acceleration, strain gauges, temperature, or humidity) or digital image and video. Algorithms for image processing and system identification are expected to be integrated to understand individual structure performance and infrastructure system resilience under extreme events.

In the past years, she has served as a member of Network for Earthquake Engineering Simulation (NEES) and the committee of national hybrid simulation task force. She has also participated and helped to organize several national and international workshops on hybrid simulation.
