The Complex Systems Team (CX Team) started out in 2007 as one of the three Complex Systems subgroups of the Instrumentation Physics Laboratory at the National Institute of Physics, University of the Philippines Diliman. It is currently headed by Dr. May T. Lim.
The group investigates sociotechnical systems that are rich in empirical data. We are actively involved in data mining social media, agent-based modeling of ecological systems, agent-based modeling of vehicular traffic, and analyzing complex networks.
