Dr. Beren Millidge

Postdoctoral Research Scientist

Beren Millidge graduated with a BA in Psychology, Philosophy, and Linguistics from the University of Oxford in 2016, and received a master's degree with distinction in Artificial Intelligence from the University of Edinburgh in 2017. He undertook doctoral work at the University of Edinburgh from September 2017, and is due to receive a doctorate in Machine Learning and Computational Neuroscience in 2021. His thesis work studied the applications of the free energy principle in neuroscience to questions in machine learning, focusing especially on mathematically characterising the exploration-exploitation trade-off in reinforcement learning, and developing and extending predictive coding models of brain function.

Beren joined the Bogacz Group in April 2021. His overarching research goal is to merge the fields of machine learning and neuroscience to try to understand how intelligence functions in brains and (eventually) in machines as well. He is especially focused on understanding questions of choice and action selection, and inference in the brain, with a focus on exploration, as well as how the cortex can perform long-term credit assignment as deep artificial neural networks do.
