The NHERI SimCenter is pleased to announce that Dr. Sang-ri Yi has joined the software development team. She is a reliability and stochastics domain expert and will expand the uncertainty quantification (UQ) capabilities of the SimCenters software. Dr. Yis work at the SimCenter will advance computational efficiency for UQ applications that entail expensive numerical models. She will also work to further streamline the integration of algorithms for UQ analysis within the various SimCenter modules, providing an easier path for end-users to contribute their own tools, said Alex Taflanidis, SimCenters UQ thrust area lead.
Dr. Yi received her Ph.D. from Seoul National University, Korea, and her B.S. (Summa Cum Laude) in Urban and Civil Engineering from Hongik University, Seoul, Korea. Her Ph.D. focus was in structural reliability and random vibrations, and her graduate research included further developing Gaussian-mixture based equivalent linearization method (GM-ELM), a nonlinear stochastic dynamic analysis method, for nonstationary excitations and accurate/efficient seismic fragility analysis; proposing a Bayesian filtering framework to monitor and forecast spatio-temporal corrosion growth of a steel structure; developing a Poisson branching process model-based first-passage probability estimation method; and developing a resilience assessment framework for cable-stayed bridges under fire hazards via adaptive surrogate model.
