Tolga Tasdizen to Serve as a USTAR Faculty Member Within the SCI Institute
Dr. Tolga Tasdizen has joined the SCI faculty as an Assistant Professor of the Department of Electrical and Computer Engineering and will become the SCI Institute's second USTAR Faculty member, joining Dr. Guido Gerig. Prior to being appointed USTAR Faculty, Tolga was a Research Assistant Professor in the School of Computing at the University of Utah. Dr. Tasdizen received his Ph.D. in Engineering from Brown University and is an expert in image processing, creating state-of-the-art research applied to biomedical and biological applications such as reconstructing neural circuit diagrams from large numbers of very high resolution microscopy images. His research interests include image analysis, computer vision and pattern recognition. The Utah Science and Technology Research Initiative (USTAR) is a state-funded, long-term effort to strengthen Utah's "knowledge economy".
Greg Jones Voted Top 100 vSpring Capital Venture Entrepreneur for 2008
Congratulations go out to our new Associate Director Greg Jones who was recently designated a v|100 - vSpring Top 100 Venture Entrepreneur. The v|100 designation is given to those individuals voted most likely to lead a successful business venture in Utah within the next few years. The v|100 is designed to help entrepreneurs and vSpring Capital establish and cultivate relationships among top CEO and CTO talent in the region. Members of this elite executive community are chosen through a peer-nominated and peer-selected process. Top members of the Utah business community were surveyed by a vSpring team to nominate the top 100 ventrue entrepreneurs in Utah. 2008 marks the fifth year of the v|100 Community. Greg was also selected as a v|100 member in 2005.
Steve Corbató Named Director of Cyberinfrastructure Strategic Initiatives at the University of Utah
The Scientific Computing and Imaging Institute congratulates Dr. Steve Corbató on being named Director of Cyberinfrastructure Strategic Initiatives at the University of Utah. Dr. Corbató has served as the SCI Institute's Associate director since May of 2006. Steve will report directly to VP of Information Technology, Steve Hess and help the University with future cyberinfrastructure plans. While Steve will be moving to the INSCC Building, we'll definitely still see him on a regular basis as we'll work together on future computing initiatives. Steve is already working on multiple projects and ideas with SCI Institute and other University of Utah faculty.

Visualizing Election Polls
A New, Animated, Interactive Way to Analyze Opinion Data Media Contacts
Oct. 6, 2008 - Do you want to know the percentage of white women who support vice presidential candidate Sarah Palin? What about college-educated versus high school-educated white women? Or those who also hunt?
University of Utah computer scientists have written software they hope eventually will allow news reporters and citizens to easily, interactively and visually answer such questions when analyzing election results, political opinion polls or other surveys.

Announcing VisTrails 1.0
Fig 1: The VisTrails history tree contains a node for each version of a workflow (or pipeline) as it evolves over time. This results in a complete audit trail of the steps that were taken in a computational task.
VisTrails is a new system that provides data and process management support for exploratory computational tasks. It combines features of both workflow and visualization systems. Like many workflow systems, it enables seamless integration of loosely-coupled resources such as specialized libraries, grid, and web services. Likewise, it parallels some visualization systems by providing a mechanism to perform parameter explorations and result comparisons. But unlike these systems, VisTrails was designed to manage exploratory activities, where computational tasks are iteratively refined as users formulate and test hypotheses. A key distinguishing feature of VisTrails is a comprehensive provenance infrastructure that maintains detailed history information about the steps followed and data derived in the course of an exploratory task. VisTrails leverages this information to provide novel operations and user interfaces that streamline this process.
The paper "Querying and Creating Visualizations by Analogy", by Carlos E. Scheidegger, Huy T. Vo, David Koop, Juliana Freire, and Cláudio Silva was selected as the "Best Paper" at IEEE Visualization 2007. In this paper, the authors introduce a new framework that allows users who are not necessarily programmers to query and refine pipelines (or workflows) by analogy. They describe a query-by-example interface which allows users to construct as complex, structure-based queries (e.g., find workflows that resample a data set before extracting an isurface) by example, using the same interface used to build pipelines. They also introduce analogy as a first-class operation to create and refine pipelines. The analogy operation allows casual users to modify pipelines without having to directly edit their definitions. These features have been implemented in their open-source workflow and provenance management system called VisTrails, which can be downloaded from the SCI Website.
