The Islamic Republic of Iran continues to defy UN Security Council resolutions calling for an end to its uranium enrichment program. Is Iran trying to develop nuclear weapons, as many fear, or does it just want to produce nuclear energy, as the Tehran government claims? What would be the likely consequences if Iran does get the bomb? What diplomatic and military options are available to address this serious crisis? Four expert panelists will discuss this issue.

A central dilemma persists for national space actors: satellites are critical to economic, scientific, and national security activities, but spacecraft are vulnerable to malfunction, environmental failure, and hostile disruptions. 'Distributed satellite' mission approaches may provide a means to supplement the security of certain satellite systems by increasing both redundancy and physical dispersion. But how do national leaders make decisions between satellite architectures given these overall risks and unknown development costs? This talk will review some current context in American space programs and present a formal model based on parallel Markov Decision Processes (MDPs) for analysis of satellite architecture decisions.


About the speaker: Matt Daniels is a 3rd year Ph.D. student in Management Science & Engineering at Stanford University and an engineer at NASA's Ames Research Center. Matt's research focuses on developing probabilistic risk models to assess the viability of constellations of small, networked satellite modules for scientific and national security missions. His doctoral research aims to improve designs for new space systems. 
 


Matt has worked at NASA Ames since 2008, where he is an engineer in the Mission Design Center and works with the Office of the Director on international technical collaborations. At NASA he has helped create NASA-DARPA partnerships on new space projects and has been a member of NASA delegations to Europe, South America, and the Middle East. As an undergraduate, Matt worked at NASA Ames, NASA Headquarters, and the Department of State. Matt received his M.S. from Stanford University in aeronautics & astronautics, and his B.A. from Cornell University in physics and international relations.

From the 1950s through the 1970s, the success of antibiotics and vaccines in controlling or eradicating infectious diseases (ID) worldwide resulted in decreased emphasis on development of ID therapeutics. The emergence in the past three decades of HIV, SARS, West Nile, avian flu, swine flu, Ebola, and the potential for bioterrorist attacks has reversed this trend and renewed interest in treatment and prophylaxis of ID. Unfortunately, because many diseases are prevalent primarily in developing nations (e.g., malaria, TB, Chagas), potential sales of bioterrorist pathogens are limited mainly to orders for government stockpiles (e.g., anthrax, smallpox, botulinum toxin), and the cost of anti-infective clinical trials is high, traditional large pharmaceutical companies have cut back R&D resources in this arena. To combat this investment shortfall, a new paradigm has emerged where public-private partnerships between the NIH, World Health Organization, private foundations, academia, and non-profits, are beginning to function like pharmaceutical companies to advance the development of promising ID drugs, even when there is little opportunity for profit. This talk will discuss the growing need for ID therapeutics, present some new models for discovering and developing them, and provide examples of public-private partnerships that have advanced therapeutics for specific infectious diseases.


About the speaker: Dr. Jon C. Mirsalis is Managing Director of the Biosciences Division and Executive Director of Preclinical Development at SRI International in Menlo Park, CA. Dr. Mirsalis is an internationally recognized expert in the development of drugs for infectious diseases. He manages two large programs for the National Institute of Allergy and Infectious Diseases (NIAID) for the development of promising therapeutics for the prevention and treatment of a broad range of infectious diseases including TB, malaria, influenza, polio, anthrax, plague, and Ebola. He has personally been involved in the development of over 50 therapeutics that have entered clinical trials and several have already reached the market. Before joining SRI in 1981, Dr. Mirsalis was a postdoctoral fellow at the Chemical Industry Institute of Toxicology, where he developed the in vivo-in vitro hepatocyte DNA repair assay, which is now widely used as a screen for potential carcinogens by government and industry. He is the author of over 140 publications and abstracts. Dr. Mirsalis received his B.S. degree in zoology/molecular biology from Kent State University, his M.S. degree in genetics from North Carolina State University, and holds Ph.D. degrees in toxicology and genetics from North Carolina State University. Dr. Mirsalis has an adjunct faculty appointment with the University of California-Santa Cruz, where he lectures regularly on genetic toxicology and carcinogenesis. He has recently served on the Board of Scientific Councilors for the National Toxicology Program, the Advisory Board for the Critical Path Institute, and is a past member of the FDA’s Over-the-Country Product Review Committee. Dr. Mirsalis has been certified by the American Board of Toxicology since 1983.

The scope of official secrecy is rapidly expanding. The sheer scale of the national security state, the growth of electronic media, and the power that still comes from compartmentalizing information means that the government is only releasing a tenth as many pages of classified information as it produces. Hundreds of millions of secret documents are piling up, raising doubts about how we will be able to reconstruct the past and ensure government accountability. But historians are now teaming up with data scientists to analyze the millions of documents that are being released. Since these were among the first official documents produced and stored on computers, we can use techniques like natural language processing and machine-learning. It may now be possible to make out the broad patterns of official secrecy, attribute authorship to anonymous documents, and perhaps even predict the content of redacted text. But the political and ethical questions remain: what does the public need to know, and when do they need to know it?


About the speaker: Matthew Connelly is professor of history at Columbia University. His publications include A Diplomatic Revolution: Algeria's Fight for Independence and the Origins of the Post-Cold War Era (2002), and Fatal Misconception: The Struggle to Control World Population (2008).
