Work

Research Engineer

• National Renewable Energy Laboratory
• May 2013-Present
• I’m having a great time leading development efforts on the building simulation tool EnergyPlus for the National Renewable Energy Laboratory. Since taking over technical development, I have overseen:
  • the conversion of the codebase from Fortran to C++ (DOE Report, Initial C++ Commit on GitHub),
  • the open sourcing onto GitHub (License),
  • the effort to make EnergyPlus a thread-safe library (One such example PR),
  • and written a new API with C and Python bindings for EnergyPlus (One Big PR).
• I’ve contributed to other projects such as
  • developing translators from raw performance data into OpenStudio components for the Technology Performance EXchange TPEX,
  • working on defects and an API for the Standard Energy Efficiency Database SEED
  • developed code and structures for the ground heat exchanger design library GHEDesigner

Graduate Assistant

• Oklahoma State University
• January 2006-May 2013
• Research tasks included:
  • Contributing to a complete re-write of the EnergyPlus central plant simulation, including solution algorithms, pump model re-work, and updating component model design
  • Developing a generalized horizontal ground heat exchanger model that includes interaction with a basement zone, specifically for use with foundation heat exchangers
  • Performing experimental measurement and modeling of transport delay phenomena in piping systems
  • Working closely with the Center for the Built Environment at University of California, Berkeley, providing simulation support for Underfloor Air Distribution System research with EnergyPlus
  • Sometimes mowing the lawn at the hybrid ground source research facility

Engineering Consultant

• Oak Ridge National Laboratory
• Fall 2007 & Summer 2009
• Tasks included:
  • Traveling to ORNL for design and kickoff sessions
  • Utilizing EnergyPlus to investigate wall constructions for residential applications, including frame walls, solid wood walls, and phase change materials
  • Building up a parametric workflow to test a wide variety of construction configurations and material properties, parsing outputs and collecting into tables and plots for publication

Engineering Intern

• Specific Systems, Tulsa, OK
• Summer 2005
• Engineering intern experience included:
  • An introduction to design and manufacturing of modular HVAC equipment
  • Designing and fabricating parts
  • Performing various mechanical and structural analysis on designs
  • Aiding in the construction of a thermal test chamber
