My research focusses on decentralised multi-energy systems, especially within residential buildings and urban environments. I am especially interested in developing and applying energy system models (ESMs) to these areas, as well as employing methods of techno-economic and environmental analysis, in order to answer diverse research questions related to the uptake and integration of low carbon technologies (LCTs). One strand of my work is focussed on methods of deriving cost-potential curves for these LCTs, which serve as an input to larger ESMs. Another strand is concerned with the ways consumers' behaviour shapes their energy demand patterns. Yet another focus is related to autonomous energy systems, involving a critical analysis of this much-discussed concept.
