Andrew Berdahl

 

Andrew is now pursuing a PhD in the Dept. of Ecology and Evolutionary Biology at Princeton University with co-supervisors Prof. Iain Couzin and Prof. Simon Levin. 

Andrew joined the Complexity Science Group at the University of Calgary as a research assistant in September 2006. From January 2007 to April 2009 he completed a Masters degree under the supervisor of Prof. Jörn Davidsen and Prof. Maya Paczuski.
