My main interest is in mathematical or analytical sociology and I am principally a methodologist focusing in the area of social networks. In particular I am interested in new non-statistical and descriptive methods such as centrality, positional analysis techniques and cohesive subgroups for networks and in the analysis of non-standard network data such as two-mode networks and networks containing negative ties.
I am involved in a number of on-going projects with colleagues both in Manchester and from other universities as follows.
A book on analyzing social networks using R.
Techniques for dealing with overlapping attributes in network data.
Directed two mode data.
