Hi everyone! I have been perusing PF for some time, and what's struck me is how little discussion there has about research in complex systems & complexity, such as the research conducted in places like the Santa Fe Institute or the Center for the Study of Complex Systems at the University of Michigan. http://www.santafe.edu/ http://lsa.umich.edu/cscs/ I'm curious if anyone here on PF (physicists, mathematicians, computer scientists, biologists, economists, etc.) are involved in complex systems research. If so, could you provide a brief summary of the nature of your research? Thanks!
