Robert received his PhD in Computer Science from North Carolina State University in 2019, under the supervision of Dave Roberts. His dissertation examined the types of latent knowledge conveyed by human-provided feedback and demonstrations, and developed interactive learning algorithms which leverage models of human behavior to extract this information. He received his Bachelor's in Computer Science from Georgia Tech in 2011. After completing his PhD, he did a two-year post-doc with Microsoft Research Cambridge, exploring the use of Reinforcement Learning and Interactive Learning in commercial game development. He also completed a post-doc at TU Delft with Frans Oliehoek, where he focused on applying game theory and multi-agent reinforcement learning to human-AI cooperation.  Robert is currently a Lecturer in Machine Learning at the University of Sheffield.
