PhD Researcher of Modelling Complex, Socio-Technical Infrastructure Systems
Steffen Blume is a doctoral researcher with the Future Resilient Systems programme at the Singapore-ETH Centre. He is part of the ‘Modelling Complex Socio-Technical Infrastructure Systems’ research module, which aims to capture human behaviour, organisational dynamics, and the mechanics of engineered systems within a unified simulation environment. His research is conducted in collaboration with the Reliability and Risk Engineering Laboratory at ETH Zürich as well as the Strategic Engineering Laboratory at NUS.
Steffen holds a M.A.Sc. degree in Mechanical Engineering from the University of Toronto and received his B.Sc. degree in Aerospace Engineering from Delft University of Technology. During his time as a research assistant at the University of Toronto, Steffen developed microsystem-level, lab-on-a-chip architectures that combine digital microfluidics and electrochemical analysis for disease biomarker detection and environmental monitoring applications.
Steffen is also the co-chair of AsETH (Association of academic staff) at the Singapore-ETH Centre. In his free time, he enjoys sports or explores the cultures and nature in South-East Asia. Steffen plays the didgeridoo, other than that he does not boast any musical talent.
Steffen’s research focuses on developing models and simulation environments as testbeds for future critical infrastructure systems. The aim is to investigate efficient algorithms and modelling techniques that can accurately represent real-world system behaviour under disruptions. In addition, the models are tailored into a framework of methodologies that enable planners and operators to create more resilient systems.
The stepped goals of this framework are to (1) assess the systems' fragility and exposure prior to any disruption; (2) analyse the system-wide effects of different disruption scenarios; and (3) develop strategic plans and immediate countermeasures that augment the recovery after disruptions.
Focusing on large-scale urban transport networks, his research involves the fields of complex systems, agent-based modelling, data analytics and statistical modelling, uncertainty analysis, stochastic simulation, and simulation-based design and optimisation.
