News

• I have received an IBM Faculty Award.
• I have received an NSF CAREER award. This award will allow my group to build infrastructure for efficiently managing workflows and their provenance, and to enable casual users (who do not necessarily have programming expertise) to perform exploratory tasks and solve problems through workflows. In this project, we will collaborate closely with scientists in the NSF Science and Technology Center for Coastal Margins Observatories & Predictions. For more details, see the award abstract.
• The International Provenance and Annotation workshop (IPAW) will be held in Salt Lake City on June 17-18, 2008. For more details, see the IPAW 2008 Web site.
• Our paper Querying and Creating Visualizations by Analogy (by Carlos Scheidegger, Huy Vo, David Koop, Juliana Freire and Claudio Silva) won the Best paper award at IEEE Visualization 2007. Here's a video that demonstrates both the query by example interface and the analogy operation.
• I have attended the SciFoo camp . This was a *very* interesting event where I learned about Cosmology, mental disorders, chemistry, and bioinformatics. I organized a session on Provenance Analytics and the future of scientific publications (more on this later).
• In September/2007, I hosted the CRA-W Distinguished Lecture series. Our distinguished speaker was Professor Susan Davidson (U Penn). For more information, see the Women in Technology Distinguished Lecture Series web page.
• Together with Simon Miles and Luc Moreau, I organized the Second Provenance Challenge
  
• Laura Haas gave the inaugural talk in our brand-new Women in Technology Distinguished Lecture Series.

Research projects

• Uncovering Hidden-Web data. Our goal in this project is to develop a scalable infrastructure that automates, to a large extent, the process of discovering, organizing, and extracting data from hidden-Web sources. For more details about this project, see http://fleixeiras.cs.utah.edu/webdb.
• VisTrails: Together with Claudio Silva from the Scientific Computing and Imaging (SCI) Institute, we are buidling a Provenance Management System that streamlines the creation, execution, and sharing of complex computations processes (aka workflows). VisTrails gives users more control over the exploratory process, simplifying many of their day-to-day activities. Our project is funded by the NSF IIS Division of Information & Intelligent Systems. For more details (and cool videos!), see the official VisTrails Web site.
• A Laboratory Workbench for Security Research . Together with Jay Lepreau and Eric Eide, we are developing new techniques and technologies that directly improve the study of security-related software systems. Our project is funded by the NSF CNS Division of Computer and Network Systems.
• Semi-structured/XML data management. I have worked on several aspects of the data management problem for semi-structured data, including:
  • Techniques and systems for storing and querying XML in relational databases:
    • LegoDB: Cost-based mapping of XML documents into relational databases
    • ShreX: an XML-to-relational mapping middleware. Beta release is available.
    • FlexMap: a flexible framework for XML schema transformations
    • Lossless and validating XML-to-relational mapping schemes that correctly support updates to mapped for XML
  • XML result estimation and statistics
    • IMAX: incrementally maintaining statistical summaries of XML documents
    • StatiX: schema-based statistical summaries of XML documents
    • StatiX++
