Experience

AT&T Research, Information Visualization and Database Research departments. Consultant, 2/13 – 12/14. Senior Inventive Scientist, 1/15 – present
Currently building tools for automatic remediation of Java software vulnerabilities, and expanding open source software for generalized semantic patching and automated learning of patches from examples
Previously created visualization tools in SVG, D3, React, WebGL, and Leaflet for data scientists and network operations

• Designed and implemented a React/Redux-based framework for automatic creation of cross-filter and drill-down dashboards from a schema
• Created an open source library for interactive network visualization, and developed applications in network topology, network monitoring, data modeling, and data flow
• Maintained and extended open source tools for interactive charting and geospatial data analysis
• Contributed to a VR platform for infrastructure planning
• Built the front end for RCloud, a collaborative notebook environment platform in JavaScript and R. Led development of extensions for compatibility with RStudio, Shiny and Jupyter
