Roughly 85% of the critical infrastructure systems in the United States is owned or operated by the private sector. Managers of these systems must keep everything running and try to ensure nothing bad happens, despite increasing system complexity and demand for continuing improvements in efficiency. This challenge naturally leads to the questions “which parts of an infrastructure are critical,” “how critical are they,” and “how should we invest limited budget to defend our infrastructure?”

We introduce two- and three-stage optimization models that represent the strategic, game-theoretic interactions between preparations to defend critical infrastructure, an “attacker” who observes these preparations before acting, and a “defender” who operates the surviving infrastructure as best as possible after an optimal attack. We identify worst-case disruptions in the operation of a system by solving a system interdiction problem. Then, given an available budget and list of possible defensive investments (e.g., hardening, redundancy, capacity expansion), we solve for a combination of investments that makes the system maximally resilient to worst-case disruption. We show some unexpected results that have proven insightful.

These models apply equally well to government, military, and commercial systems. Between our NPS student-officers and faculty, we have conducted over 150 case studies on systems ranging from electric power, to transportation, to supply chains, to the Internet.

About the speaker: David L. Alderson, Ph.D, joined the Naval Postgraduate School faculty in 2006 after working for three years as a postdoctoral scholar in the Division of Engineering and Applied Sciences at the California Institute of Technology (Caltech). He received a B.S.E. in Civil Engineering and Operations Research from Princeton University and the M.S. and Ph.D. degrees from the Department of Management Science and Engineering at Stanford University. His research focuses on the function and operation of critical infrastructures, with particular emphasis on how to invest limited resources to ensure efficient and resilient performance in the face of accidents, failures, natural disasters, or deliberate attacks. He currently serves as the Director of the NPS Center for Infrastructure Defense (CID). As part of a Multiple University Research Initiative (MURI) team studying "Next-Generation Network Science," he studies tradeoffs between efficiency, complexity, and fragility in a wide variety of public and private network-centric systems. He has extensive experience working on the Internet and other complex communication networks, having been a researcher at the Xerox Palo Alto Research Center (PARC), the Santa Fe Institute (SFI), and the Institute for Pure and Applied Mathematics (IPAM) at UCLA. He is a member of INFORMS and MORS.

On May 14, the Center for Northeast Asian Policy Studies (CNAPS) at Brookings and the Center on Democracy, Development, and the Rule of Law (CDDRL) at Stanford University hosted a seminar analyzing progress and challenges in the consolidation of Taiwan’s democratization and reforms. While the presidential and legislative elections held on January 14 were interpreted by many as proof that Taiwan’s democratic system—including its government and society—has matured since the first transition of political power in 2000, both big-picture and day-to-day challenges to effective democratic governance remain.

The seminar featured leading practitioners and political scientists from Taiwan and the United States. Panelists examined reforms that have been enacted in Taiwan over the past decade, and analyzed their impact on the functions of government agencies, political parties, and other non-governmental organizations. They also discussed how reform and consolidation are affecting policy and public perception of the system.

In spring 2009, China’s leadership announced ambitious national health reforms. Have the five stated goals of the first three years of reform been met? What policies will China pursue in the next phase? As a prominent advisor to China's State Council Health Reform Office, Liu will discuss progress and prospects for reforms—especially the role of the private sector within the health system—within the context of China’s 2012 leadership transition.

Gordon Liu is a professor of economics at Peking University's (PKU) Guanghua School of Management, and director of PKU's China Center for Health Economic Research. Previously, he served as a tenured associate professor at the University of North Carolina at Chapel Hill (2000–2006), and as an assistant professor at the University of Southern California (1994–2000).

Liu's primary research interests include health and development economics, health policy and reform, and pharmaceutical economics. His current research is funded by the State Council Health Reform Office, the National Science Foundation, UNICEF, and the China Medical Board.

Liu currently serves on the State Council Health Reform Advisory Commission, and the Expert Panel for the State Ministry of Human Resource and Social Security. He serves as co-editor for the journal Value in Health, and as editor-in-chief for China Journal of Pharmaceutical Economics. He sits on the editorial boards for the European Health Economic Review, Global Handbook for Health Economics, and Chinese Journal of Health Economics.

He received his PhD in Economics from the City University of New York Graduate School while working as a graduate research fellow at the National Bureau of Economic Research under the supervision of Michael Grossman (1986–1991). He obtained post-doctoral training at Harvard University with William Hsiao (1992–1993). Liu has served as the president for the Chinese Economists Society, and chair for the Asian Consortium for the International Society for Pharmacoeconomics and Outcomes Research.

Location-based services from are quickly gaining popularity. Many such services track the user's location and make use of it as needed. While tracking raises privacy concerns, it is believed to be unavoidable if users want the benefits of location-based services. In this talk I will give several examples of services that provide location-based functionality without learning the user's location. Our goal is to show that privacy and functionality are not always in conflict. We will also discuss our experiences with deploying these mechanisms in the real world. This is joint work with Arvind Narayanan, Mike Hamburg, and Narendran Thiagarajan.

About the speaker: Dr. Boneh heads the applied crypto group at the Computer Science
department at Stanford University. Dr. Boneh's research focuses on applications of cryptography to computer security. His work includes cryptosystems with novel properties, security for mobile devices, web security, digital copyright protection, and cryptanalysis. He is the author of over a hundred technical publications in the field and a recipient of the Packard Award, the Alfred P. Sloan Award, the RSA award, and the Terman Award.
