Robert Ackland holds a PhD in Economics from the Australian National University, MA (Economics) from Yale University and B. Commerce (Economics) from the University of Melbourne and is a Research Fellow in the Research School of Social Sciences at the ANU. Robert's PhD research was in the application of index number theory to global comparisons of income and poverty. Since 1994, he has worked as a consultant in poverty analysis and targeting for organizations such as The World Bank (based in Washington. D.C., 1995-1997), Asian Development Bank and AusAID and has also worked on capacity building projects in these areas. More recently, Robert moved into a new area of research at the intersection of information science and empirical social science -- the development of new methods (and associated software) for quantitative analysis of social and economic phenomena on the Internet. Robert is developing research methods that combine information retrieval, data visualization and more traditional quantitative social science methods and is co-Chief Investigator on an Australian Research Council (ARC) Discovery Project titled "New Methods for Researching the Existence and Impact of Political Networks on the WWW" (2004-2006). He is also co-chief investigator on an ARC Special Research Initiative (e-Research Support) project for the establishment of the Virtual Observatory for the Study of Online Networks. Robert is taking a leading role in establishing e-Research in the social sciences (or e-Social Science) in Australia, and co-organized the First Australian e-Social Science Symposium, held at the ANU in November 2004.
Lada A. Adamic is an assistant professor in the School of Information. Her research interests center on information dynamics in networks: how information diffuses, how it can be found, and how it influences the evolution of a network's structure. She worked previously in Hewlett-Packard's Information Dynamics Lab on research projects relating to networks constructed from large data sets. These projects included mining the medical literature for gene-disease connections, tracking and modeling information flow in E-mail and blog networks, modeling search processes on real-world social networks, and building expertise-finding systems.
Eytan Adar is currently a graduate student at the University of Washington in the Computer Science and Engineering department. Most recently he was a researcher at HP Labs and at Xerox PARC before that. His research focus is the study of the behavior of large user populations in digital spaces. In general, he is very interested in the study and application of information side-effects. These are the pieces of data that users produce as part of their daily digital existence. Though not originally intended for this purpose, the data can be used to construct novel tools (e.g. building better search by using web-surfing behavior) as well as mined to answer fundamental questions of individual and social behavior. An example of this is his work with Lada Adamic on modeling and predicting information propagation by analyzing weblogs. Understanding these networks requires large-scale crawls and the application of computationally intensive algorithms and he is very interested in infrastructures that support this kind of research. Another recent, and continuing, project is the Graph Exploration System (GUESS). GUESS allows researchers in many fields to explore, analyze, and visualize networks using a domain specific language (an extension of Python). The language supports work with graphs where nodes and edges have arbitrary properties as well as the construction of new visualization applications. The Java-based system is available under a GPL license from http://www.graphexploration.org/. He received his Bachelor and Master degrees at MIT in Computer Science. More information and papers are available at http://www.cond.org/.

Larry Brandt joined the National Science Foundation (NSF) in 1976 and in 1984 he was a member of the management team for NSF's Office of Advanced Scientific Computing. Larry stayed with the Supercomputer Centers program for 14 years as a program manager. In the early 1990s Larry made several small grants to the undergraduates on the software development team at NCSA, resulting in the first multimedia Web browser (Mosaic) and a related server in January of 1993. To respond to the demand of early Web users for better faster Mosaic development, Larry assembled a consortium of 15 interested Federal agencies who agreed to provide $3M over three years. Generalizing from that experience, in 1998 Larry created and still manages the NSF's Digital Government research program, which funds collaboration between academic researchers and government agencies. Valerie Gregg, on detail from the US Census Bureau to NSF, was the key collaborator in the program's development. The Digital Government program crosses all computer and information science disciplines and all gov't domains and missions, from international and Federal agencies to local levels and supports primarily technical projects. In the last three years, an additional emphasis on projects from the policy, organizational, political and social sciences has been added. These encompass, for example, projects to explore the impact of IT on government organizations, the impact of IT on democracy, and e-voting. The program has funded over 100 research grants, with a current budget of about $10M per year. More about the program can be found at the web site http://www.digitalgovernment.org/.

Doug Gregor's background is in the areas of programming languages, programming methodologies, compilers, and the construction of high-performance, generic software libraries. The last of these is directly relevant to this workshop, because the Open Systems Laboratory has been developing generic software libraries of graph (network) algorithms and data structures for several years. The best known of these projects is the generic Boost Graph Library (BGL), available http://www.boost.org/libs/graph/doc/. More recently, Goug Gregor and his colleagues have developed the Parallel BGL, available at http://www.osl.iu.edu/research/pbgl/, which extends the BGL to parallel computation on clusters, allowing them to perform queries on graphs with tens of millions of nodes and billions of edges within a few seconds on a medium-sized cluster. For all their capabilities, the BGL and Parallel BGL are only low-level infrastructure libraries on which one could build interesting applications for social network analysis.

Caroline Haythornthwaite is Associate Professor at the Graduate School of Library and Information Science, University of Illinois at Urbana-Champaign. Her research examines how the Internet and computer media support and affect work, learning, and social interaction. Her research examines how information is exchanged, knowledge is shared and co-constructed, collaboration happens, and community forms. Studies have examined social networks of work and media use among researchers, the formation of social networks and media use over time in online classes, and social networks of knowledge sharing in collaborative research teams. Other work examines the development and nature of community online, communication issues for new online learners, distributed knowledge processes, and the nature and constraints of interdisciplinary collaboration. Her studies of social networks and media use show that those with stronger ties communicate via more media than weakly ties pairs (media multiplexity), and that, within groups, media are found in pairs' repertoires in a similar order. This suggests that group mandated means of communication provide a 'latent tie' structure on which pairs can build weak and then stronger ties (see papers in The Information Society, and Information, Communication and Society). Major publications include The Internet in Everyday Life (2002, edited with Barry Wellman); Learning, Culture and Community in Online Education: Research and Practice (2004, edited with Michelle M. Kazmer), a special issue of Journal of Computer-Mediated Communication on "Computer-Mediated Collaborative Practices and Systems" (2005), and Handbook of E-learning Research (in preparation, edited with Richard Andrews).

Raquell Holmes received her Ph.D. in the area of cellular, developmental biology from Tufts Sackler School of Biomedical Sciences. After a post doc at Dana Farber Cancer Research Institute she joined Boston University's Center for Computational Science to manage the Education, Outreach and Training Partnership for Advanced Computational Infrastructure (EOT-PACI). Her focus in the context of EOT-PACI and now EPIC (Engaging People in CyberInfrastructure) has been on building community within and beyond the NSF funded partnerships. In addition to participating in the leadership of EOT-PACI, Dr. Holmes headed the development of the EOT-PACI website and Metrics Online. These tools served the partnership and its audiences by making visible the activities and products of the PACI partners. The development of the Metrics tool required establishing rudimentary measures of collaboration within the partnerships. This has included linkages between institutions, projects and specific events or products. An historical overview of the tools development has been posted. Dr. Holmes also develops materials for training biologists in the area of modeling and simulation. This work builds on the computational science education and training efforts within EPIC, identifies numerical modeling applications easy to use for biologists and supplements these tools with curricular materials and professional development workshops. Through this work Dr. Holmes has developed a high-level understanding of metabolic pathways, biological database implementations and distinctions between static and dynamic analyses of biological systems at the cellular and molecular levels.

Karrie Karahalios is an assistant professor in the Computer Science department at the University of Illinois at Urbana-Champaign. Her work focuses on the interaction between people and the social cues they perceive in networked electronic spaces. Of particular interest are interfaces for pubic online and physical gathering spaces such as chatrooms, cafes, parks, etc. The goal is to create interfaces that enable users to perceive conversational patterns that are present, but not obvious, in traditional communication interfaces. Her most recent work involved integrating social catalysts into the design of interfaces for connecting spaces using audio and video. Previous projects include: Visiphone, a communication object that visualizes conversation patterns between two spaces; Hear&Here, an augmented reality interface for placing sound envelopes in space and retrieving them with an audio interface; Chit Chat Club, a hybrid social space that combines the immediacy of the traditional cafe with the global reach and easy introductions of an online chat. Ongoing research involves (i) analyzing patterns in cell phone conversations among groups of people and visualizing them to get a better understanding of mobile conversation patterns. (2) developing interfaces for incorporating emotion into mediated communication archives. (3) developing interactive furniture interfaces for collocated interaction among people about a table to show "value" on communication. Karrie completed a SB in electrical engineering, an MEng in electrical engineering and computer science, and an SM in media arts and science and a PhD in media arts and science at MIT.

Laura Koehly, Ph.D. is an Investigator in the National Human Genome Research Institutes of the National Institutes of Health. She is the Head of the Social Network Methods Section of the Social and Behavioral Research Branch. Dr. Koehly completed her Ph.D. in quantitative psychology at the University of Illinois - Urbana/Champaign, after which she completed post-doctoral training at the University of Texas M.D. Anderson Cancer Center. Her current research focuses on the development of social network methodologies to measure and model the complexities of family systems, the utilization of these methods to understand the social, psychological, and communicative context of families at risk for hereditary disease, and the translation of this understanding into effective network-based interventions that facilitate the delivery of genetic counseling services and dissemination of risk information. Her work extends traditional approaches that focus on a single family member to a social network approach, which allows one to develop a more realistic understanding of the dissemination process when communicating health information through a family. Additionally, she is interested in understanding how formal support systems, such as health care providers (i.e. genetic counselors, general practitioners) participate in the process of decision making, communication and support for at-risk family members. Dr. Koehly's methodological research interests focus on the development of stochastic models for three-way social network data and interdependent ego-centered network data.

He holds a PhD in political science from the University of Michigan.
Roger Leenders is an associate professor of Business Development at the School of Management, University of Groningen, The Netherlands. His main research interest is in how social networks within and between groups/teams of individuals affect the performance of groups and teams. Primarily, he studies the effect of intra- and interteam networks on the creativity and innovativeness of teams and on the creation of knowledge by teams. His main empirical field is that of teams involved in R&D, both in goods and services. He both studies teams of co-located iundivuals and virtual sets of teams that communicate through electronic means. In addition to the study of creativity and knowledge, a second major field of study relates to the modeling of social influence. Here he has developed network autocorrelation models that allow one to estimate and test various regimes of influence that may occur through network relations. From a more substantive point of view he studies language patterns that people use to influence their network partners. This also ties in with work in which he studies how social networks can be created/influenced/engineered so as to increase payoff for (all or several) network members. Being an econometrician by training, he enjoys building mathematical and statistical models of social networks. As a business scholar, he enjoys the creation and testing of theory. He received his Ph.D. at the Interuniversity Center for Social Science Theory and Methodology, University of Groningen. His papers have appeared in a variety of journals such as Social Networks, Journal of Mathematical Sociology, Journal of Engineering and Technology Management, Journal of Product Innovation Management, Creativity and Innovation Management, Technovation, Team Performance Management.
Michael Macy is Professor and Chair of Sociology at Cornell. In a series of studies funded by the National Science Foundation, his research team used computational models and laboratory experiments with human subjects to explore how threshold effects in network interactions might generate familiar but enigmatic social patterns, such as the emergence and collapse of fads, the spread of self-destructive behaviors, and the polarization of opinion. Macy pioneered the use of agent based models in sociology to explore the effects of heterogeneity, bounded rationality, and network structure on the dynamics and stability of social systems (http://hsd.soc.cornell.edu/Macy.htm). He now heads a team of social, information, and computer scientists who are building tools that will make the Internet Archive accessible for research on social and information networks (http://www.nsf.gov/news/news_summ.jsp?cntn_id=104477). He also leads a Cornell initiative to promote cross-disciplinary collaborative research and teaching on social and information networks.

W. Bradford Paley uses computers to create visual displays with the goal of making readable, clear, and engaging expressions of complex data. His visual representations are inspired by the calm, richly layered information in natural scenes. His process applies three perspectives:  rendering methods used by fine artists and graphic artists are  informed by their possible underpinnings in human perception, then  applied to creating narrowly-scoped, almost idiosyncratic representations whose visual semantics are often driven by the real-world metaphors of the experts who know the domains best. Brad did his first computer graphics in 1973, graduated Phi Beta Kappa from UC Berkeley in 1981, founded Digital Image Design Incorporated in 1982, and started doing financial & statistical data visualization in 1986. He has exhibited at the Museum of Modern Art; he created TextArc.org; he is in the ARTPORT collection of the Whitney Museum of American Art; has received multiple grants and awards for both art and design, and his designs are at work every day in the hands of brokers on the floor of the New York Stock Exchange. He is an adjunct associate professor at Columbia University, and is director of Information Esthetics: a fledgling interdisciplinary group exploring the creation and interpretation of data representations that are both readable and esthetically satisfying.

Catherine Plaisant, PhD, is Associate Research Scientist and Associate Director of the Human-Computer Interaction Laboratory of the University of Maryland Institute for Advanced Computer Studies. She earned a Doctorat d'Ingénieur degree in France in 1982 and worked on developing and evaluating user interfaces since then. In 1987 she joined Professor Ben Shneiderman at the Human-Computer Interaction Laboratory of the University of Maryland. She works with graduate students from Computer Science, Information Studies or Psychology on designing and evaluating new interface technologies that are useable, useful, and appealing. Research contributions range from focused interaction techniques to innovative visualization techniques validated with user studies and practical applications. The activities that are most relevant to the focus of this workshop all concern the design and evaluation of user interface. Current projects include two user interfaces that look for alternative to the traditional node link diagrams to explore network data: NetLens (which uses coordinated overviews and sorted lists) and TreePlus (which investigate interactive tree representations to present graphs). In an effort to promote the evaluation of information visualization and the development of benchmarks I started the InfoVis Contest which topic in 2004 was the History of InfoVis. Participants were judged on how much insights they could provide about the data (the papers and authors of 10 years of the conference).

Bill Richards. Network researchers have used eigen decomposition methods either implicitly or explicitly since the late 1960's, when computers became generally accessible in most universities. There are a number of problems with both the methods currently in use and what have come to be seen as "standard" ways of using those methods. The main goal of his research is to develop a unifying theoretical perspective that will address the problems mentioned above, and that will tie together analytic methods previously understood as being unrelated to one another by providing clear links to the mathematical foundation on which they stand, namely algebraic graph theory. His research activities have centered largely around the development and implementation of computer programs for the analysis of communication/information networks: Negopy, MultiNet. A number of research papers he wrote with Andrew Seary are available at http://www.sfu.ca/~richards/Pages/ResearchPapers.html. Besides developing analytic packages such as Negopy and MultiNet, he has presented papers and workshops about eigen analysis methods at annual international conferences of INSNA and ICA. In 2001 Andrew Seary and Bill Richards analysed data for a study of Multiple Chemical Sensitivity involving over 2000 people, 100 symptoms, and 150 exposures, using MultiNet and a new analytic strategy and obtained results showing a clear relationship between symptoms and exposures that had not been seen before. Subsequently, they were asked to extend the methods for use in an NIH-funded multi-national study of Colon Cancer. They attended the symposium on Social Network Analysis for National Security, hosted by the Committee on Human Factors of the National Academy of Sciences, in Washington, D.C., November 7-9, 2002 (http://www.nap.edu/books/0309089522/html/209.html). In August, 2000 Richards organized a Symposium on Networks, Needles, Drugs, Risk, and Infectious Disease that brought 24 network experts and public health practitioners together for three days to examine the social networks of drug users and determine which research strategies would be likely to lead to useful advances. A follow-up meeting will take place in April, 2006 before the annual INSNA Sunbelt Social Network conference.
Garry Robins is a mathematical psychologist whose research deals with quantitative models for social and relational systems. Methodologically, he focuses on statistical models for social networks, and in particular exponential random graph models (p* models). These models assume that a large-scale network emerges from combinations of local patterns of interaction among small overlapping subsets of people. Such patterns can often be interpreted as the result of a localized social process, a set of behaviours within each subset of individuals. As a result, these models provide ways to examine large scale network structures (the macro- or global level) as the ramification of overlapping and intersecting localized behavioural patterns (the micro- or local level). He has generalised these models to include actor attributes, leading to social influence models and social selection models. More recently, together with his colleagues, Robins has developed new versions of these models, including social settings and new higher order network statistics (Snijders, Pattison, Robins & Handcock, 2005). These new specifications show a dramatically better performance, including in model estimation and fit. They have developed new programs for Monte Carlo maximum likelihood estimation to replace previous approximate estimation techniques. Current work includes: elaborations for directed networks, for multiple networks, and for bipartite graphs; and further development of estimation software. Robins collaborates in many empirical social network research projects, including: structure of sexual networks and HIV transmission; the social epidemiology of mental health in rural areas; health policy and local government networks; environmental governance arrangements; intra-organizational networks; defence-related issues; labor market dynamics; communication networks and stereotype formation; social structures and cultures in sporting teams; political processes; interlocking directorates.

Ramon Sangüesa is a professor at UPC, the Technical University of Catalonia, Barcelona, Spain as well as member of the i2CAT Foundation for Advanced Internet in Catalonia where he coordinates the development of grid computing infrastructures and applications, geared towards collaborative environments. His background comes from Artificial Intelligence with research on Intelligent Agents, Artificial Societies and Machine Learning. His current interests are focused on the emergence on collaborative social and knowledge networks and the integration of different types of technologies for collaboration (from the "low level" upwards: grid, agents, social and knowledge networks, web2.0 applications and interfaces). His current research on social and social networks is centered around the mechanisms of reciprocity, trust, reputation in the interchange of knowledge between agents in a society. Recent work explores the relationship between these characteristics and the emergence of several types of networks. Some of the results of this research has been applied to the e-government projecte e-catalunya by the Catalana Autonomous Government.

Munindar P. Singh, PhD, is a professor in the department of computer science at North Carolina State University. Dr. Munindar's research interests include multiagent systems and service-oriented computing, wherein he addresses the challenges of trust, service selection, and business processes and protocols in large-scale open environments. Munindar has studied adaptive social networks from a computational perspective. At one level, he treats social networks as a basis for knowledge management in groups and organizations. At a deeper level, he treats social networks as a fundamental programming abstraction to support decentralized service selection and trust estimation. In the first, improved infrastructure would enable better mining, management, and exploitation of social networks. In the second, social networks underlie trustworthy use of infrastructure by supporting the dynamic configuration of effective virtual organizations. Munindar is widely published and has over 150 articles to his name. Munindar's books include Multiagent Systems (published by Springer-Verlag in 1994) and the coauthored text, Service-Oriented Computing: Semantics, Processes, Agents (published by Wiley in 2005). Munindar was the editor-in-chief of IEEE Internet Computing from 1999 to 2002 and continues to serve on its editorial board. He is also a member of the editorial boards of the Journal of Autonomous Agents and Multiagent Systems and the Journal of Web Semantics. He was general cochair of the 2005 edition of the International Joint Conference on Autonomous Agents and Multiagent Systems. Munindar's research has been recognized with awards and sponsorship by the National Science Foundation, DARPA, IBM, Cisco Systems, and Ericsson.
