Tim was a cybersecurity postdoctoral fellow at CISAC for 2012-2014 and remains a CISAC affiliate. He is a cybersecurity fellow at the Hoover Institution for 2014-2015. He received his PhD in political science from the University of Pennsylvania in 2013. His research is on information technology and national security. His dissertation focused on cyber warfare strategy, and how variation in domestic politics -- particularly stemming from principal-agent problems and bounded rationality -- may cause bureaucracies or leaders to use offensive cyber capabilities. Tim is testing his theories with comparative fieldwork on how the United States, South Korea, and Taiwan produce and project cyber power. In his spare time, Tim develops new cyber capabilities at the Defense Advanced Research Projects Agency (DARPA).
Before beginning his PhD studies, Tim received his MA from Johns Hopkins University's School of Advanced International Studies (SAIS), concentrating in Strategic Studies and International Economics, and his BA from Johns Hopkins' undergraduate program in International Studies. He worked on cyber security strategy and analysis for the Office of the Secretary of Defense, RAND Corporation, US intelligence community, and Johns Hopkins' Information Security Institute.
