    Timothy Gulden is a research assistant professor with the Center for Social Complexity in the Krasnow Institute for Advanced Study at George Mason University. He completed his PhD at the UMD School of Public Policy in December of 2004 with a dissertation entitled "Adaptive Agent Modeling in a Policy Context." He has been a visiting scholar at the Brookings Institution's Center on Social and Economic Dynamics (CSED), a research Scholar at the Center for International and Security Studies at Maryland (CISSM) and attended the Santa Fe Institute's Complex Systems Summer School in 2002.
