The Modeling and Simulation (M&S) Engineering Graduate Research Assistant (GRA) assists with research, development, and testing teams to combine simulation modeling with data analytics in order to provide recommendations to optimize system designs in support of current and future research, development, and testing efforts. Specifically, the M&S needs require someone that is responsible for helping construct computer simulation models, helping verify and validate simulation models, performing simulation experiments to predict system behaviors, and helping improve systems and processes.
