I’m James Clough, a PhD student in Physics at Imperial College London – this is my personal website. I am currently working in the Centre for Complexity Science (formerly the Complexity & Networks group) at Imperial, supervised by Dr. Tim Evans, and Prof. Kim Christensen. My research is in complex networks, and my interest is particularly in networks constrained by causality, such as citation networks. My work focuses on using the special constraints and properties of these networks to find new ways of characterising and modelling their structure. Other academic interests include game theory, statistics and other aspects of complexity science, such as applications in economics and government policy.
