Josh Rushton is a contract analyst with Regional Technical Forum (RTF). He is an experienced energy efficiency evaluator with expertise in research design and data management, modeling, and analysis.

Prior to the RTF, Dr. Rushton worked on program impact evaluations at the Cadmus Group. At Cadmus, he developed sampling plans and performed custom data analyses. He also co-authored the Sample Statistics chapter of the Uniform Methods Project.Dr. Rushton earned his Ph.D. in mathematics at the University of Wisconsin, with a specialization in probability theory and stochastic processes. Prior to working in energy efficiency, he worked as a post-doctoral researcher and lecturer at Cornell University and as a visiting assistant professor at Portland State University.

Josh lives in Portland with his wife and two kids. He enjoys spending time with family, hiking, trail running, and reading. His favorite programming language is R.

Christian Douglass is an engineer with nearly 10 years of experience researching, analyzing, and modeling energy usage in buildings. For the past six years, Christian has provided technical and management support to the Regional Technical Forum (RTF) and the Northwest Power and Conservation Council, contributing to assessments of energy efficiency measures, development of RTF and Council analysis tools, and management of technical subcommittees. Before joining the RTF as a contract analyst, Christian worked as a Senior Consultant at Navigant Consulting, where he worked primarily on utility program impact evaluations and energy efficiency potential studies. Prior to Navigant, Christian conducted building energy research and analysis both as an intern at Oak Ridge National Laboratory and as a graduate student at the University of Illinois. Christian holds a B.S. in General Engineering and M.S. in Systems and Entrepreneurial Engineering from the University of Illinois at Urbana-Champaign.

When Christian is not working, he likes to spend time with his family and pets, go on hikes, and find any excuse to build things. He is also a big fan of chocolate, donuts, and of course, chocolate donuts.

Eric Shum is a registered professional engineer with substantial experience working across energy efficiency and demand side management projects. His expertise includes complex engineering analysis for conventional and emerging technologies, equipment survival and building stock modeling, field measurement and verification, building and process level equipment and controls inspection, market characterization and assessment, codes and standards impact analysis, utility portfolio assessments, cost research and valuation, and big data interpretation and management.

Eric is heavily engaged in developing energy simulation data inputs and forecast models for the residential, commercial, industrial, and agricultural sectors, at both at the measure and sector-end use levels nationally.

Ryan Firestone is an experienced engineer with a background in engineering analysis, energy-use modeling, and site verification and survey. He has applied his analytic expertise to analyses of a broad range of demand side management technologies and applications. His tasks as an RTF Contract Analyst include developing and updating conservation measure assessments, supporting cross-measure analyses, and contributing to updates to the ProCost measure cost-effectiveness tool. Prior to the RTF, he worked at Navigant Consulting on demand side management (DSM) impact evaluations, conservation potential studies, and related analysis and Excel/VBA-based tool development. Ryan has also worked at the Lawrence Berkeley National Laboratory for five years on investment and operations optimization of small-scale distributed generation systems. Additional work experience includes developing photovoltaic and electric storage design optimization tools and managing the University of Texas El Paso Wind Energy Research Laboratory. Ryan holds a B.S. from Brown University, a M.S. from the University of Texas at El Paso, and a Ph.D. from the University of California at Berkeley, all in Mechanical Engineering.

Ryan's hobbies include playing with his two small children, gardening, and running. He is also a Parks and Recreation Commissioner for the City of Ojai, California. Other than his RTF work, his most notable achievement was walking 3,000 miles from Florida to California after college.

Gregory Brown is a contract analyst with the Regional Technical Forum. As an experienced economist and statistician, Greg has worked on a broad range of energy efficiency measure evaluations and characterizations. His work includes sample design, econometric analysis of billing data, behavioral and demand response programs, and statistical analysis of evaluation and research plans. Prior to joining the RTF as a contract analyst, Greg worked at Navigant Consulting for five years, focusing on energy efficiency program evaluation.

Previous to energy efficiency consulting, he worked in the financial sector, with a focus on energy and commodity stocks and cash flow analysis. During this time, he became a CFA Charterholder. Greg completed his undergraduate degree at New York University and received an M.S. in Applied Economics and Energy Policy from the University of Wisconsin, Madison.

In his spare time, he enjoys traveling, running, reading about politics and space exploration, long walks on the beach, poker, and watching others play video games.
