Modeling & Simulation Specialists focus on developing predictive models that represent system behavior across technical, environmental, or operational domains. Their work includes model formulation, parameter estimation, scenario analysis, and sensitivity studies to support planning and optimization. They integrate data, domain knowledge, and simulation techniques to evaluate system performance and future outcomes. These specialists work in engineering, environmental planning, defense analysis, healthcare modeling, and policy-support environments. Globally, demand is increasing as organizations rely on predictive modeling and simulation to manage uncertainty, assess risk, and guide strategic decisions in complex, data-rich systems.
