A little more about Emil...

I am currently a third year PhD student at Brunel University in London, and my research is focused in the fields of language acquisition and air transportation. The purpose of this work is to investigate and to compare the evolution of two completely unrelated networks, originating from these two fields.  

For language acquisition, a sample of children’s early linguistic development is modelled using word co-occurrence networks, which specify the adjacency of words within children’s utterances. Extensive network modelling and analysis of statistical parameters of these networks has shown that children’s syntax acquisition is rule-based, and can be generally approximated by a simulation model called MOSAIC.

For air transportation, the evolution of the United States Airport Network (USAN) over the past twenty years is modelled as a directed, weighted network. Here, a link represents the presence of passengers on a non-stop flight from A to B in a specified time period, and the weight is the total number of those passengers.  The results show that the networks from both fields follow a power-law degree distribution, but different weight distribution, suggesting that their topological structure is somewhat similar (scale-free, small-world), but the dynamics on the network are different.
