I am interested in developing safe and robust machine learning systems that behave in the way we expect, and thus able to work with humans effectively. My work has often explored inverse reinforcement learning and imitation learning in order to learn from humans, and I’m interested in using this knowledge and generative AI to create insight and develop personalised, human-centric, decision making systems.
