My primary informal site is now netplexity.org which contains the descriptive material and my blog. Code, papers and talks are still stored here.

There is a wealth of data on academic publications, going back 100 years or more, and this is now held electronically. Some is freely available, some is not but access can be purchased. There is great commercial interest in the analysis of this data too, as it represents an important output from academics and a marker of the research and innovation process. Bibliometrics is therefore an ideal area for the application of ideas from Complexity and Networks.

I am interested in this data at various levels. It poses interesting questions in terms of theoretical graph analysis. The data is of real personal and commercial interest in that this is now used to look at the performance of researchers or researcher units such as Universities. Thus any ideas can be tested and then applied in the real world. This data can be seen as the best documented footprint of innovation processes in the human society so there are broad and fascinating social science questions which might be studied. This interest overlaps with many aspects of my other work.

• A paper looking at citation networks in general (with James Clough, Jamie Gollings and Tamar Loach). Looks at some general techniques for analysing what are known as DAGs - Directed Acyclic Graphs. We did this both on theoretical models, some of which are used in the causal sets approach to quantum gravity, and on real data including a citation network derived from the arXiv preprint database. A version is on arXiv as Transitive Reduction of Citation Networks, arXiv:1310.8224.
• Poster (with with N.Hopkins and B.Kaube): Temporal Evolution Of Universal Performance Indicators For Academic Publication given at the ECCS 2012, Brussels, 4th September 2012. Based on paper below with same authors.
• Talk: Scaling and Citations given at the EPSRC Workshop on Scaling in Social Systems Saïd Business School, Oxford, 1st December 2011.

• Paper: Universality of Performance Indicators based on Citation and Reference Counts with N.Hopkins and B.Kaube (to appear in Scientometrics, 2012) [arxiv:1110.3271]. This looks at data from a single institute and from the arXiv electronic repository and finds a log normal shape to the citations to papers published under the same field (defined in different ways) and in the same time span (usually one calendar year), provided one normalises with respect to the average number of citations in each group of papers.
• With Renaud Lambiotte (IMS, Imperial College) and Pietro Panzarasa (School of Business and Management, Queen Mary University of London) we have written a paper entitled "Community Structure and Patterns of Scientific Collaboration in Business and Management" (Scientometrics, 2011, 89, 381-396) [arXiv:1006.1788].
• With Karen Gurney of Evidence (a division of ThomsonReuters) and Daniel Hook of Symplectic Ltd, Imperial College and Washington University, St. Louis, USA, we have a poster from the INORMS conference entitled "Collaboration Profiling in UK Higher Education"
• I have longer term contact with Symplectic Ltd who produce software making day-to-day information management easier for leading academic institutions across the world. Managing academic publications is an important part of their work.
