On November 11, the Institute of Electrical and Electronics Engineers (IEEE) presented its 2014 Visualization and Technical Achievement Award to Claudio T. Silva, Head of Disciplines at CUSP and professor of Computer Science and Engineering at NYU’s Polytechnic School of Engineering.
The award, one of the highest honors given by the IEEE Computer Science Society’s Technical Committee on Visualization and Graphics (VGTC), recognizes Silva’s seminal advances to geometric computing for visualization and contributions to the development of the VisTrails data exploration system. The committee also cited Silva’s participation in various multidisciplinary projects.
VisTrails systematically maintains provenance for the data exploration process by capturing all the steps researchers follow in the course of an experiment—much like document-tracking applications in Microsoft Word and Google Docs track changes to a document. Tracking provenance is essential because that information allows a researcher to accurately reproduce his or her own results or the results of others, even if they involve hundreds of parameters and complex data sets.
“Consider that when a researcher is engaged in an exploratory process, working with simulations, data analysis, and visualization, for example, very little is repeated during the analysis process; change is the norm, and new workflows are constantly being generated,” Silva explained. “VisTrails manages these rapidly evolving workflows. To make a simple analogy, using it is like having someone in the lab watching over your shoulder and taking concise notes.”
“Clauio Silva has blazed a trail of innovation in visualization that has strongly influenced many researchers, including myself,” said Amitabh Varshney, director of the IEEE Visualization and Graphics Technical Committee and a professor of computer science and the director of the Institute for Advanced Computer Studies at the University of Maryland. “One of the reasons his work has had such a significant impact is because it combines elegant foundational research with real-world applications. This award is a well-deserved recognition of Claudio’s illustrious accomplishments and stunning impact.”
