tional Analysis of Social and Organizational Systems. Dr. Carley received a Ph.D. in sociology from Harvard University. Her research combines cognitive science, social networks, and computer science. Her specific research areas are computational social and organization theory; group, organizational, and social adaptation and evolution; dynamic network analysis; computational text analysis; and the impact of telecommunication technologies and policy on communication, information diffusion, disease contagion, and response within and among groups particularly in disaster or crisis situations. Her models meld multiagent technology with network dynamics and empirical data. She has developed a number of tools for extracting (AutoMap), analyzing (ORA), and reasoning about change in (Construct, DyNet) social and knowledge networks. Three of the large-scale multiagent network models she and her group have developed are BioWar, a city-scale model of weaponized biological attacks; OrgAhead, a model of strategic and natural organizational adaptation; and Construct, a model of the coevolution of social and knowledge networks and personal/ organizational identity and capability. She is the founding coeditor of the journal Computational and Mathematical Organization Theory and has coedited several books in the multiagent and dynamic social networks area. She was a member of the National Research Council’s (NRC’s) Panel on Modeling Human Behavior and Command Decision Making: Representations for Military Simulations.


Paul K. Davis is a senior scientist and research leader at RAND and a professor of policy analysis in the RAND Graduate School. His current research relates to strategic planning; high-level decision support; representing adversary reasoning; capabilities-based planning; effects-based operations; deterrence in the counterterrorism era; military transformation; advanced methods for modeling and simulation, including model composability; and missile defense. Dr. Davis teaches graduate courses in defense planning, counterterrorism policy, and policy analysis of strategy problems with massive uncertainty. Dr. Davis has served on a number of studies for the Defense Science Board. He was awarded the Vance R. Wanner award by the Military Operations Research Society for lifetime achievement. Before joining RAND, Dr. Davis was a senior executive in the Office of the Secretary of Defense. He holds a B.S. from the University of Michigan and a Ph.D. in chemical physics from MIT. He was at one time a member of the NRC’s Naval Studies Board and served on several of its committees.


Richard Ivanetich is Institute Fellow at the Institute for Defense Analyses (IDA), having been appointed to that position in 2003. His experience spans a number of areas of defense systems, technology, and operations analyses, relating primarily to computer and information systems, command-and-control systems and procedures, modeling and simulation of systems and forces, crisis management, and strategic and theater nuclear forces. His previous positions at IDA include director of the Computer and Software Engineering Division (1990-2002) and assistant director of the System Evaluation Division (1985-1990). Prior to joining IDA in 1975, Dr. Ivanetich was assistant professor of physics at Harvard University (1969-1974). He has served on numerous scientific boards and advisory committees, among them the NRC’s Naval Studies Board (1998-2004) and the DARPA Information Science and Technology study group (1990-2004).


Kathryn B. Laskey is a professor of systems engineering and operations research at George Mason University. She received her master’s degree in mathematics from the University of Michigan and her Ph.D. in statistics and public affairs from Carnegie Mellon University. Dr. Laskey studies Bayesian inference and decision theory, multisource fusion, uncertainty in artificial intelligence, and situation assessment. Her broad research interest is the use of information technology to support better inference and decision making. Within this area, her interests lie in understanding the proper role of normative, behavioral, and computational theories in the modeling and support of decision making. Dr. Laskey is a research fellow with the Krasnow Institute for Cognitive Science at George Mason University (GMU) and associate director of the Center of Excellence in Command, Control, Communications and Intelligence at GMU. She has been on several NRC committees, including the committee that wrote the 2001-2002 study on scientific evidence on the polygraph.


R. Bowen Loftin is vice president and chief executive officer of Texas A&M University at Galveston. He has worked extensively in the academic community as a researcher, instructor, and mentor. In 1977 he joined the faculty of the University of Houston-Downtown. In 1994 he founded the NASA/University of Houston Virtual Environments Research Institute and in 1999 became the chair of the Department of Computer Science at the University of Houston. He received the University of Houston-Downtown Excellence in Teaching Award in 1982 and the Excellence in Service Award in 1984 and 1985. For the past 5 years he has served as executive director of a research center at Old Dominion University in Virginia while also managing the university’s multidisciplinary graduate degree programs in modeling and simulation. Under his tenure there, the master’s student enrollment increased to over 50 students and the doctoral student population increased from 2 to over 40 students. His major field of research is modeling, analysis, and simulation. He holds Ph.D. and M.A. degrees in physics from Rice University and a B.S. in physics from Texas A&M University. He has written numerous articles on topics as varied as artificial intelligence, virtual reality, and computer-aided training and simulations. He has won multiple awards, including various NASA awards for inventions, publications, and public service in 1989, 1992, 1993, 1994, and 1995.
