Our Management Team

Martin Mayfield, Director
Martin Mayfield, DirectorProfessor of Engineering Design
Martin leads the Urban Flows’ work on energy, air quality and the modelling of urban processes as complex systems. He is currently leading the Observatory work on developing our digital models, data capture and the exploration of methods to identify features of the built environment. His current work includes the exploration of the relationships between decarbonisation, power grid characteristics and thermal energy demand across scales in order to establish how cities can efficiently decarbonise their energy systems. His objective for the Observatory is to understand the flow of energy, resources and materials across scales and systems in order to help cities reduce their total impact upon the planet.
Daniel Coca, Director
Daniel Coca, DirectorProfessor of Nonlinear and Complex Systems
Viewing modern cities as systems-of-systems, Daniel is interested in developing a framework for integrating, analysing and modelling in real-time the data generated by large heterogeneous arrays of sensors across multiple spatial and temporal scales, to help understand the emergent properties of cities, to characterise their performance – especially city resilience and robustness – and to provide a quantitative basis for designing urban policies and forecasting their impact through exploratory simulation analyses and optimization.

Dr. Grant Wilson
Dr. Grant WilsonTeaching and Research Fellow, Energy and Environmental Engineering Group, Department of Chemical Engineering
Grant’s research interests lie in integrated energy systems analysis and more and more in the challenges in data collation and dissemination at different temporal and spatial levels of granularity. The interaction between differing energy systems, demand management, and active network management is key to understanding the routes to enhance network flexibility and resilience on a number of timescales. Long-term, reducing our use of fossil fuels brings challenges in terms of the provision of stored energy available to energy systems to provide a balance between supply and demand. This stored energy challenge needs to be addressed to enable the energy systems to fully decarbonise.
