Ji-Eun Byun

Dr Ji-Eun Byun is a Lecturer at the University of Glasgow, moving to Imperial College London as an Assistant Professor in the Department of Civil and Environmental Engineering in May 2026. Her research addresses the risk and resilience of complex infrastructure networks — transport, energy, water — under natural and human-made hazards, from flooding and earthquakes to ageing assets. Her methodology is built around Bayesian networks: graphical probabilistic models whose visual structure makes them well suited to interdisciplinary collaboration on risk assessment and decision-making for complex systems. She works specifically on lowering the adoption barrier and scalability limits of system risk tools through advanced Bayesian network methods and open-source tool-kits. 

During the Fellowship, Dr Byun will deliver two risk-assessment workflows on the DAFNI platform, built around a highway transport network exposed to earthquake hazards. The first will demonstrate a full network risk-assessment cycle, connecting hazard models, component fragilities, system simulations, and decision metrics. The second, more ambitious workflow will integrate alternative simulation functions within a single pipeline, working towards a digital twin environment that supports multi-model, evidence-based discussion of complex networks. She will also engage stakeholders across sectors to explore practically viable shared digital twin environments for managing national infrastructure.
