Our group conducts research on the structure and function of networks,
particularly social and information networks, which we study using a
combination of empirical methods, analysis, and computer simulation. Among
other things, we have investigated scientific coauthorship networks,
citation networks, email networks, friendship networks, epidemiological
contact networks, and animal social networks; we've studied fundamental
network properties such as degree distributions, centrality measures,
assortative mixing, vertex similarity, and community structure, and made
analytic or computer models of disease propagation, friendship formation,
the spread of computer viruses, the Internet, and network navigation
algorithms.

My book
Networks: An Introduction was published in 2010 by Oxford University
Press. Information about it is here. The Amazon

With Daniel Dorling and Anna
Barford, we have a new book of maps available, The Atlas of the Real
World, containing 366 cartograms showing all kinds of different
features of the world today. Details here.
