Brian Ball joined NREL in June 2010. His expertise is in modeling, control and simulation of physical systems as well as numerical analysis and numerical methods. His experience includes solving partial differential equations, nonlinear equations and optimization, multiscale modeling, and control of smart material systems. At NREL, Ball specializes in hardware in the loop simulation at the campus level for the Energy System Integration program, developing inverse modeling algorithms to calibrate building energy models, and is part of the OpenStudio development team. In addition, Ball has worked on several large-scale sector analysis projects, including U.S. Department of Energy Asset Score, and helped developed the Cloud computing environment for OpenStudio. 

Prior to joining NREL, Ball was a simulation engineer for General Electric Energy modeling power plants and related equipment. This work included developing an engineering grade operator training simulator for an integrated coal gasification combined cycle power plant.
