Colloquium Details

Exploratory Visualization

Speaker: Claudio Silva, NYU-Poly

Location: Warren Weaver Hall 1302

Date: January 27, 2012, 11:30 a.m.

Host: Denis Zorin

Synopsis:

The process of analyzing large volumes of data is exploratory in nature---it is a search for clues, where some might be misleading but others lead to discovery. Exploratory visualization is a key tool in this process, allowing scientists to more effectively formulate hypotheses, which might be confirmed with other standard techniques.

We take the view that future advances in science, engineering, and medicine depend on the ability to comprehend the vast amounts of data being produced and acquired. Visualization is a key enabling technology in this endeavor: it helps people explore and explain data through software systems that provide a static or interactive visual representation.

Despite the promise that visualization can serve as an effective enabler of advances in other disciplines, the application of visualization technology is non-trivial. The design of effective visualizations is a complex process that requires understanding of existing techniques and how they relate to human cognition. For a visualization to be useful, it needs to be both effective and efficient. This requires a combination of design and science to reveal information that is otherwise obscured.

In this talk, we will discuss recent work on the development of interactive visualization techniques and tools that is being done in my group.

Speaker Bio:

Claudio T. Silva is Professor of Computer Science and Engineering at the Polytechnic Institute of NYU. From 2003 to 2011, he was with the School of Computing and the Scientific Computing and Imaging Institute at the University of Utah. He coauthored more than 175 technical papers and eight U.S. patents, primarily in visualization, geometric processing, scientific data management, and related areas. He received IBM Faculty Awards in 2005, 2006, and 2007, and best paper awards at IEEE Visualization 2007, IEEE Shape Modeling International 2008, the 2010 Eurographics Educator Program, the ACM Eurographics Symposium on Parallel Graphics and Visualization 2011, and EuroVis 2011. His work is (or has been) funded by grants from the NSF, NIH, DOE, IBM, and ExxonMobil.
