Liz Varga has expertise in trans-disciplinary research projects across infrastructure systems (energy, transport, water, waste and telecoms) via her research projects, engagements with practice and feedback from dissemination. Her skills are in creating abstractions of real-world systems, recognizing emergent phenomena and co-evolutionary effects, together with measurable systemic metrics. She leads the design of computational agent-based models which represent the dynamics of inter-connected systems. She has experience of system transitions, modelling the effects of policy, technology and innovation under different future scenarios, and analysing computational results representing economic, environmental and societal effects. She won the Cranfield University Research Award in 2014 and again in 2016.
Liz is Head of the Infrastructure Systems Group at Cranfield School of Management, creating evolutionary models of critical infrastructure systems embracing social, technical, economic and policy factors using various futures scenarios. She also runs the Complex Systems Research Centre.
