Areas of Research: Neural computation in sensory processing

Professional Interests

Our lab studies neural computation to advance understanding of how the brain produces perceptual experiences and guides behavior. Broad research topics in the lab include Natural vision: Why computers can beat us at chess but don’t come close (yet) to our ability of understanding the world around us through our eyes? Behavioral variability: Why it is so hard to make 100 free throws in a row even if the basket doesn’t move? Uncertainty in perceptual decision-making: How do we decide when it is safe to cross the road in heavy fog? We address these topics from the perspective of probabilistic inference, and develop computational models and experiments to probe how networks of neurons interact when evaluating the probability of different possible interpretations of the sensory input. We follow a highly interdisciplinary approach that combines theories of neural coding, advanced methods in machine learning and computer vision, psychophysics experiments, and in vivo electrophysiology through collaborations. In the longer run, we hope this research will contribute to elucidating how the brain produces the vivid, coherent, stable percepts we experience in everyday life; and to advancing technologies that could restore impaired vision and enhance normal vision.
