Kurzinfo

From a brief glimpse of a complex scene, we recognize people and objects, their relationships to each other, and the overall gist of the scene – all within a few hundred milliseconds and with no apparent effort. What are the computations underlying this remarkable ability and how are they implemented in the brain?

My current research addresses these questions by bridging recent advances in machine learning with human behavioral and neural data to provide a computationally precise account of how visual recognition works in humans. Specifically, we leverage the recent successes in artificial neural networks of vision to address long-standing questions concerning human visual perception and the functional organization of the human visual cortex.
