My research aims to understand the principles underlying biological and artificial intelligence. Humans and animals produce amazingly complex behaviors, in the face of changing environments and often with little to no supervision. This has led me to study the structure of neural representations in perceptual and physiological experiments, asking how our visual system might enable such behaviors.
At DeepMind, I have been investigating self-supervised algorithms that extract structure from raw data, enabling data-efficient image recognition, behaviorally-relevant scene understanding, and unsupervised object discovery and temporal correspondence. More recently, I have been interested in how visual representations might structure our memory, enabling flexible perceptual inference and long-video understanding.
Prior to joining DeepMind, I completed my PhD at NYU's Center for Neural Science, advised by Eero Simoncelli. Before starting research, I studied math and physics at École Polytechnique and Lycée Sainte Geneviève.
