About the Topic: Japan’s March 2011 Great Tohoku earthquake and tsunami led to core damage in three reactors at the Fukushima Dai-ichi nuclear power station. This presentation will describe both the short-term and long-term actions of the U.S. Nuclear Regulatory Commission (NRC) to implement lessons learned from the Fukushima accident and will highlight Commissioner Apostolakis’ views on the accident. The presentation will also describe the findings of the Commissioner’s Risk Management Task Force chartered to develop a strategic vision and options for adopting a more comprehensive and holistic risk-informed, performance-based regulatory approach for the NRC.

About the Speaker: George Apostolakis was sworn in as a Commissioner of the U.S. Nuclear Regulatory Commission (NRC) on April 23, 2010, to a term ending on June 30, 2014. 

Dr. Apostolakis has had a distinguished career as an engineer, professor and risk analyst. Before joining the NRC, he was a professor of Nuclear Science and Engineering and a professor of Engineering Systems at the Massachusetts Institute of Technology.  He was also a member and former Chairman of the statutory Advisory Committee on Reactor Safeguards of the NRC. In 2007, he was elected to the National Academy of Engineering for "innovations in the theory and practice of probabilistic risk assessment and risk management." He received the Tommy Thompson Award for his contributions to improvement of reactor safety in 1999 and the Arthur Holly Compton Award in Education in 2005 from the American Nuclear Society.

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.

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.
