Stephen C. North

North, Stephen C.
180 Park Ave - Building 103
Florham Park, NJ
Subject matter expert in graph visualization, visualization systems, applied algorithms

Stephen is Executive Director of Information Visualization Research. He works on systems and algorithms for visualizing and interactively exploring large, complex structures; and the general problem of applying computational geometry to visualization of abstract information with the goal of approaching the quality of hand-made graphics. Stephen is one of the authors of the Graphviz system. His group also created the core software for Vizgems, a software platform run by AT&T for its internal operations and enterprise customers. Vizgems collects, analyzes and displays near-realtime information at large scale for numerous managed services, and currently has about 100,000 endpoint devices. Stephen received a Ph.D. in Computer Science from Princeton University in 1986.
