Research

Research in the Risk and Decision Analysis Laboratory is focused on integrating probabilistic risk analysis methods (e.g., dynamic probabilistic risk assessment) with advanced decision-making methods (e.g., reinforcement learning) to improve the safety, security, and efficiency of safety-critical systems, such as nuclear power plants and electric power systems.
