Research interests & expertise

Energy systems

I plan and lead research on energy systems and building science. I conduct energy audits of lighting, HVAC, applances, and commercial & industrial processes. I conduct engineering analyses; oversee data quality control; verify and recommend changes to savings algorithms in multiple states' technical reference manuals; and conduct intrerviews with downstream and midstream market actors.

Data Science

I lead efforts to improve the accuracy and reproducibility of data-intensive projects. I plan and develop robust, scalable solutions to business problems. I can understand complex systems, troubleshoot issues, and drive innovation in data science tooling. I stay up-to-date with tools for carrying out performant, reproducible data science.

Program Evaluation

I develop survey instruments, field collection data forms, samples, analyses, and reporting for process and impact evaluations of energy-efficiency programs, including low-income and First Nattions programs in the US and Canada. I conduct interviews with market actors, literature reviews, and cross-jurisdictional scans of technical reference manuals.
