DESCRIPTION:Rumours are an important from of social communications and the
 ir spreading plays a significant role in a variety of human affairs.  In t
 his talk I will give an overview of our ongoing research on theory and mod
 elling of rumour spreading in complex social networks. A general mathemati
 cal model for the spreading of stochastic rumours on large social networks
  is introduced and the critical properties and spreading dynamics of rumou
 rs on several models of social networks\, including random graphs\, scale-
 free networks\, small world networks and random geometric graphs are inves
 tigated via a combination of mathematical modelling and numerical simulati
 ons. Finally\, the impact of l correlations and clustering on the dynamics
  of rumour spreading are studied. Some initial results on modelling corrup
 tion contagion in organizational networks will be presented.  \n  \nSee al

 Scientist at BT Research and an Honorary Senior Fellow at University Colle
 ge London. He received his MSc. in Electrical Engineering (cum laude) from
  Delft University of Technology in the Netherlands and his PhD in theoreti
 cal Physics from the University of Nijmegen\, also in the Netherlands. Dr 
 Nekovee’s research cuts across several science and engineering disciplin
 es and involves collaborations with statistical physicists\, applied mathe
 maticians\, management scientists and computer scientists. His current res
 earch focuses on theory\, mathematical modelling and applications of compl
 ex networked systems\, including social networks\, computer networks and w
 ireless telecommunication networks.  Dr Nekovee is the recipient of a pres
 tigious Industry Fellowship from the Royal Society.  His new book on “Co
 gnitive Radio Communication and Networks: Principle and Practice”  was p
 ublished recently by Elsevier/Academic Press.
