Brian W. Bush is a Principal Strategic Analyst in the Energy Forecasting & Modeling group of the National Renewable Energy Laboratory’s Strategic Energy Analysis Center. He received a B.S. in physics at the California Institute of Technology in 1985 and a Ph.D. in theoretical physics at Yale University in 1990, where he was a National Science Foundation graduate fellow. From 1992 to 2008 he worked as a Technical Staff Member in the Energy & Environmental Analysis Group at Los Alamos National Laboratory. His research focuses on the modeling and simulation of infrastructure systems, particularly energy and transportation networks, with an emphasis understanding the effects of interdependencies between complex systems. He currently leads NREL’s Biomass Scenario Model project, a system-dynamics simulation of the cellulosic biomass-to-biofuels supply chain.
