Robert Alexander Lefebvre


Mr. Rob Lefebvre is currently an R&D Staff member at Oak Ridge National Laboratory (ORNL) in the Reactor and Nuclear Systems Division where he has been employed since 2009. As the SCALE Software Production Coordinator, he serves the SCALE development and leadership teams in tasks related to software continuous integration, performance optimization, quality assurance, development iterations, feature and release planning, user experience and interaction, and defect remediation. 

As the DOE-NE Nuclear Energy Advanced Modeling and Simulation project (NEAMS) Workbench Work Package manager, he collaborates with staff from five national laboratories and contractors related to enabling users to optimize usage of existing modeling and simulation tools, and lower barriers to the use of advanced NEAMS tools.

As the Consortium for Advanced Simulation of Light Water Reactors (CASL) Physics Integration (PHI) Infrastructure (INF)  lead, he collaborates with developers on the Virtual Environment for Reactor Applications (VERA)'s overall software architecture and design, system integration and administration, developer tools and maintenance,  and software testing, deployment, and user support.

His early work experience includes graphical user interface development, data visualization, software language interoperability, performance optimization, language pragmatics, cross-platform software, legacy code insulation and modernization, process and workflow management, and data-driven application-agnostic computational analysis for spent nuclear fuel.
