Dr Dick James 


The main focus of my research is to develop and use computational methods for the analysis of patterns and processes in populations of social animals. Almost all my work is now done in collaboration with biologists. I am interested in the interplay between local movement rules and global patterns of aggregation, but my particular interest is in the use of network theory to unravel the social structure of group-living animals such as fish, ungulates and mammals, and the dynamics of the passage of goods through colonies of social insects.
