Profile

Nick McCullen is a Lecturer in the Department of Architecture and Civil Engineering.  He is interested in how the complex interactions between the various components, such as buildings, technology, the environment, and people, result in the energy consumption of the built environment.

Nick gained his undergraduate Master’s degree in Physics at the University of Manchester. He spent two years teaching English in rural Japan on the Japan Exchange Teaching (JET) programme before returning for his PhD in the Manchester Centre for Nonlinear Dynamics. On this he researched chaotic phenomena in coupled oscillators, with application to many complex behaviours arising from the interactions between simple systems. One application of the research was sensitive signal detection, related to the resonant coupling of oscillations found in insect hearing.

Nick's first post-doctoral research position was at the University of Bath, investigating electrical network models of composite materials in the Bath Institute for Complex Systems.This involved modelling the microstructure of these materials as many individual elements coupled via a network of interactions between them, to understand the macroscopic, system level 'emergent properties' observed in physical experiments.

This line of research led him to the University of Leeds as part of the multi-disciplinary project Future energy decision—making for cities: Can complexity science rise to the challenge. Nick's work involved mathematical and computational modelling of the influence of various factors affecting the uptake of energy efficiency innovations by individual households in a city, including the influence of peers via their personal social network.

Research

Nick is currently involved in research proposals related to the modelling of the vastly complex city energy systems and end users to better understand energy use in cities and homes.

A part of this is working out what measures will be necessary to address the twin challenge of making cities capable of both remaining habitable by adapting to the possible effects of future climate change, and also mitigating further change by providing the energy needs of their citizens more sustainably.
