## Biography

Nick’s research focuses on the intersection of machine learning, probability theory, and partial differential equations with an emphasis on scientific and engineering applications. Prior to joining Sandia, he directed his research toward the construction of operator networks (neural networks designed to approximate operators rather than functions) endowed with predictive uncertainty estimates to help gauge the accuracy of model predictions. His current research is concentrated on the development of reinforcement learning techniques aimed to help guide policies and design strategies involving complex physical systems.
