Ji-Eun Byun is Assistant Professor in the Department of Civil and Environmental Engineering (CEE) at Imperial College London (ICL). 

Ji-Eun's research group works on probabilistic and computational methods for reliability, resilience, and risk assessment of complex infrastructure systems under uncertainty. Key research themes include: Bayesian network methodology for high-dimensional systems; system reliability analysis of networked infrastructure; reliability-based optimisation and decision-support; and AI/ML methods for surrogate modelling and inference. Application domains span rail networks, power and energy grids, transport systems, and earthquake disaster risk. 

Ji-Eun leads the development of open-source toolkits for scalable system reliability and Bayesian network inference, including MBNpy. 

Ji-Eun previously held a Humboldt Postdoctoral Research Fellowship at the Technical University of Munich and completed a PhD at Seoul National University.
