Carlos E. Scheidegger

Scheidegger, Carlos E.
180 Park Ave - Building 103
Florham Park, NJ
Subject matter expert in Scientific Visualization, Geometric Processing

Carlos joined AT&T in September 2009, after finishing his PhD at the SCI Institute and the School of Computing, at the University of Utah. In graduate school, he worked in scientific visualization and geometric processing, with applications in mesh generation and point-based surface representations. His thesis work focused on managing the provenance of scientific visualizations: the process in which the users arrive at the visualizations they design. During that period, he was one of the main designers and developers of VisTrails. VisTrails is a new visualization system whose goal is to provide scientists with an infrastructure that helps the exploration process inherent in developing effective visualizations. VisTrails emphasizes the importance of process provenance: it transparently keeps track of the visualizations as they are created.
