A postdoctoral position in Human collective behavior is available at the Department of Mathematics, Uppsala University.
The collective behavior research group uses a combination of mathematical models and experiments to understand the dynamics of animal and human groups. See http://www2.math.uu.se/~david/web/ for details of their current research. Some current projects on humans involve the study of socially contagious activities, such as audience clapping, and of how individuals integrate social and personal information when trying to answer trivia questions. They collaborate closely in this work with an experimental research group led by Prof. Jens Krause in Berlin.
An opening is currently available for a postdoctoral researcher to work on similar projects, from a perspective that combines mathematical modelling with experimental work.
Full details of the position and how to apply can be found at: http://www2.personalavd.uu.se/ledigaplatser/2450postDOC.html. Applications should be submitted no later than November 18th, 2011.
