Postdoctoral Research Associate, Grid-interactive Controls Group, Oak Ridge National Laboratory
I design and build the digital tools that connect buildings, grids and the people inside them. I draw the system diagrams, write the software, and design the interfaces that make building data usable.
Two first-author ORNL technical reports published on OSTI: a generalizable web user interface for deploying building energy management systems in small and medium-sized commercial buildings (ORNL/TM-2026/4715, [DOI]), and low-cost, customizable heating and cooling management for small and medium-sized medical office buildings (ORNL/TM-2026/4854, [DOI]).
First-author ORNL technical report on extending the supervisory controller kit to small and medium industrial facilities, a literature-based feasibility assessment (ORNL/TM-2026/4735, [DOI]).
Paper on simulation-based validation of an open-source building energy management framework published in the Proceedings of SimBuild 2026, Minneapolis [DOI]. Also served as a SimBuild 2026 session chair.
Joined the DOE Building Technologies Office project on extending the supervisory controller kit to small and medium industrial facilities, as a contributor and developer.
Completed the Ph.D. in Architectural Sciences at Rensselaer Polytechnic Institute and joined ORNL as a Postdoctoral Research Associate in the Grid-interactive Controls Group.
Received the Faculty Graduate Recognition Award for Excellent Academic Achievement, RPI.
Three themes, one aim: buildings whose data, controls and interfaces work together.
One building description that holds across design, simulation and operation. My Ph.D. framework connects BIM, building energy models, building automation and occupant behavior through IFC, Brick, SHACL and obXML.
Open-source building energy management for small and medium-sized commercial buildings, which are 94% of U.S. commercial buildings and nearly half of commercial building energy use. At ORNL I am a contributor and developer on DOE Building Technologies Office projects that combine model predictive control, VOLTTRON, Brick models, BACnet and Modbus.
How occupants, operators and intelligent building systems inform each other. My monitoring work links BIM, IoT sensors and building automation to track indoor air quality and occupant behavior, tested in university laboratory and meeting-room pilots.
The software I write for my research: what each tool does, the languages it uses, and its code.
ORBIT
Open-source, scalable software platform for building energy management in small and medium-sized commercial buildings.
gb-obXML Converter
Translates gbXML to obXML so that occupant behavior models can enter BIM-to-BEM simulation workflows.
Comfit
Prototype digital twin dashboard that visualizes IoT sensor data on a BIM model in real time.
Design is part of how I do research: I design the interfaces and visualizations of the tools I build, and I bring computational and architectural design into building technology.
Interfaces and visualizations for my own tools: the generalizable web user interface for deploying building energy management systems (ORNL/TM-2026/4715), and the Comfit digital twin dashboard, which shows IoT sensor data on a BIM model in real time.
Parametric modeling in Grasshopper, and a generative-design study at Autodesk that coupled design generation with natural ventilation simulation in EnergyPlus. The study resulted in two U.S. patent applications and a SimBuild 2024 paper.
