Christopher Blattman is currently completing a PhD in economics at UC Berkeley and holds a master's degree from Harvard's Kennedy School of Government. His research focuses on the causes and consequences of conflict and violence, the organization of guerrilla groups, as well as what post-conflict development policies work, for whom, and why. He recently completed a survey of war-affected men and boys in northern Uganda, and is presently conducting a similar survey of women and girls. Two randomized evaluations of post-conflict programs are planned in the same region for 2007, one studying the role of a group-based economic intervention in promoting community reintegration of ex-combatants, and another studying the introduction of a government and an independent press into communities not currently served by newspapers.

James Fearon is the Theodore and Frances Geballe Professor in the School of Humanities and Sciences, a professor of political science and CISAC affiliated faculty member at Stanford University. His research has focused on democracy and international disputes, explanations for interstate wars, and, most recently, the causes of civil and especially ethnic violence. He is presently working on a book manuscript (with David Laitin) on civil war since 1945. Representative publications include "Neotrusteeship and the Problem of Weak States" (International Security, Spring 2004), "Ethnicity, Insurgency, and Civil War" (APSR, February 2003), and "Rationalist Explanations for War" (International Organization, Summer 1995). Fearon won the 1999 Karl Deutsch Award, which is "presented annually to a scholar under the age of forty, or within ten years of the acquisition of his or her doctoral degree, who is judged to have made, through a body publications, the most significant contribution to the study of international relations and peace research." He was elected as a fellow of the American Academy of the Arts and Sciences in 2002.

Dara Kay Cohen is a PhD candidate in political science at Stanford University and was a fellow and research assistant at CISAC in 2004-2005 and 2005-2006. Her research at CISAC involved studying the politics of national security; she examined the creation of the Department of Homeland Security, how security issues have affected congressional elections and co-wrote a paper with Jacob N. Shapiro on the failure of the homeland security alert system. Her current dissertation research focuses on the use of sexual violence during civil wars, and she spend last summer in Sierra Leone conducting initial field work. She previously worked at the Department of Justice as a paralegal in the Outstanding Scholars Program in the Counterterrorism Section and at the u.S. Embassy in London on terrorist financing issues. She received her a.B. in political science and philosophy with honors from Brown University in 2001.

Mariano-Florentino Cuéllar, with a PhD in political science from Stanford as well as a law degree from Yale, focuses his scholarship on how organizations cope with the legal responsibility for managing complex criminal justice, regulatory, and international security problems. He has published the leading academic paper on the operation of federal money laundering laws, and one of the most exhaustive empirical case studies of public participation in regulatory rulemaking proceedings. Recent projects address the role of criminal enforcement in managing transnational threats, the physical safety of refugee communities in the developing world, legislative and budgetary dynamics affecting the federal Department of Homeland Security, and the impact of bureaucratic structure on how institutions implement legal mandates. Professor Cuéllar is an affiliated faculty member at the Stanford Center for International Security and Cooperation, and a member of the Executive committee for the Stanford International Initiative. Before joining the Stanford Law School faculty in 2001, he served as senior advisor to the u.S. Treasury Department's Undersecretary for Enforcement and clerked for Chief Judge Mary M. Schroeder of the U.S. Court of Appeals for the Ninth Circuit.

A key pillar and unmet need in the defense against threats to health is the ability to recognize the etiological factor(s) and predict the course of disease, at early points in the timeline of the process. This ability would enable early intervention in the disease process when there is the greatest likelihood of benefit, as well as triaging of hosts, based on individual need. Genomic tools and approaches have enabled a more detailed description of host-microbe encounters, and shed light on fundamentally important processes, including the cellular responses associated with infection. Genome-wide transcript-abundance profiles, like other comprehensive molecular readouts of host physiological state, provide a detailed blueprint of the host-pathogen dialogue during microbial disease. Studies of cancer based on genome-wide transcript-abundance profiles have led to novel signatures that predict disease outcome and serve as useful clinical classifiers. The highly dynamic and compartmentalized aspects of the host response to pathogens complicate efforts to identify predictive signatures for infectious diseases. Yet, studies of systemic infectious diseases so far suggest the possibility of successfully discriminating between different types (classes) of infection and predicting clinical outcome. In addition, host gene expression analysis could lead to the identification of early signatures associated with a protective immune response, both to natural infection and to vaccination. Early explorations in some of these areas indicate the potential feasibility of this approach but also point to important unmet challenges.

David Relman is associate professor of medicine, and of microbiology and immunology at Stanford University. He is also chief, infectious diseases section, at the VA Palo Alto Health Care System in Palo Alto, California.

A native of Boston, Massachusetts, Relman holds an SB degree from the Massachusetts Institute of Technology and received his MD degree, magna cum laude, from Harvard Medical School in 1982. Following postdoctoral clinical training at Massachusetts General Hospital in internal medicine and in infectious diseases, Relman served as a postdoctoral research fellow in microbiology at Stanford University in the laboratory of Stanley Falkow from 1986 until 1992. He joined the Stanford University faculty in 1992 and was appointed associate professor (with tenure) in 2001. His research is directed towards the characterization of the human indigenous microbial communities of the mouth and gut, with emphasis on understanding variation in diversity, succession, the effects of disturbance, and the role of these communities in oral and intestinal disease.

Experimental approaches include molecular phylogenetics, ecological statistics, single cell genomics, and community-wide metagenomics. A second area of research concerns the classification structure of humans and non-human primates with systemic infectious diseases, based on patterns of genome-wide gene transcript abundance in blood and other tissues. The goals of this work are to recognize classes of pathogen and predict clinical outcome at early time points in the disease process, as well as gain further insights into virulence (e.g., of variola and monkeypox viruses). Past achievements include the description of a novel approach for identifying previously-unknown pathogens (selected as one of the 50 most important papers of the last century by the American Society for Microbiology), the identification of a number of new human microbial pathogens, including the agent of Whipple's disease, and the most extensive descriptions to date of the human indigenous microbial community. See http://relman.stanford.edu. Relman received the Squibb Award from the Infectious Diseases Society of America (2001), the Senior Scholar Award in Global Infectious Diseases from the Ellison Medical Foundation (2002), and is a recipient of an NIH Director's Pioneer Award (2006). He is a member of the American Society for Clinical Investigation and was named a Fellow of the American Academy of Microbiology in 2003.

Relman currently serves on the Board of Scientific Counselors of the National Institute of Dental and Craniofacial Research and was a member of the Board of Directors of the Infectious Diseases Society of America (2003-2006), and co-chair of the National Academy of Sciences' Committee on Advances in Technology and the Prevention of Their Application to Next Generation Biowarfare (2004-2006). He is a member of the National Science Advisory Board for Biosecurity, the Institute of Medicine's Forum on Microbial Threats, and advises several U.S. Government departments and agencies on matters related to microbial pathogen detection and future biological threats.
