Stephen North
Founder at Infovisible
New Jersey, United States
Summary
🤩
RockstarStephen North is a founder and seasoned visualization and data-analysis engineer with 11 years in his own consultancy and decades of earlier research leadership at AT&T Labs and Bell Labs. He co-invented Graphviz and continues to maintain and improve its codebase, contributing bug fixes and new primitives that keep the project relevant across bioinformatics, security, and network operations. At AT&T he built and led R&D teams and shipped high-impact systems—from carrier-scale visualization platforms to Nanocubes and cloud R analytics—that bridged prototypes to production. Now running Infovisible from New Jersey, he consults on graph- and network-focused visualization, prototyping innovative tools and advising technical teams. He combines deep algorithmic knowledge with practical systems experience, and is active in the IEEE VIS community where he helps steer the field’s direction. An unexpected angle: he pairs hands-on low-level code fixes with strategic research leadership, so he’s as comfortable merging a branch as shaping multi-project research roadmaps.
