Research Interest Summary
Research Interests
We use computational techniques including machine learning, signal processing, network analysis, and deep learning to understand how the brain turns the light that falls onto our eyes into the rich, meaningful experience that we perceive in the world around us. We use signals recorded directly from the human brain through electrodes implanted in epilepsy patients (intracranial electroencephalography) and non-invasive magnetoencephalography to probe the neurodynamics that underpin high level perception, including word reading, object recognition, face perception, and social and affective perception.
