Ruonan Ou is currently a PhD student in Systems, Civil and Environmental Engineering Department at UC Berkeley. Her research focuses on the application of distributed fiber optic sensing technology (DFOS) in structure health monitoring (SHM), especially on the early stage detection of crack and the dynamic traffic tracking. She works on developing algorithms to overcome the spatial resolution issue of Brillouin Scattering-based sensing system and applies them to monitor the crack generation in the pavement and the levee cutoff wall. Her work also includes tracking the vehicle movement on the pavement using dynamic DFOS. Her research aims to contribute to smart city and infrastructure.

She obtained her B.Eng. in Civil Engineering from Harbin Institute of Technology (HIT) in 2016 and her M.Eng. in Systems, Civil and Environmental Engineering from UC Berkeley in 2017. In the fall semester of 2014, she studied as an exchange student in the University of Hong Kong. In HIT, she researched FEM-based seismic vulnerability analysis of latticed shells and the mechanism of passive pile group caused by tunneling.
