Laura Lewis

I'm a Junior Fellow in the Harvard Society of Fellows, where I study the neuroscience of sleep, anesthesia, and altered states of consciousness. My research focuses on how the brain switches between different dynamical states, and how these states shape our perception of the outside world. To enable us to study these brain states in humans, I also develop neuroimaging and computational techniques that enable new kinds of measurements and analyses of brain activity.

What happens in the brain when a person wakes up or falls asleep? What are the circuit mechanisms that control the brain's arousal state and how do they alter information processing? I use several methods to investigate these questions, including intracranial recordings in human patients receiving general anesthesia, optogenetic manipulation of sleep circuits, multimodal neuroimaging (EEG and fMRI) of sleep, and novel statistical and computational methods to analyze neural data.

I completed my Ph.D. in Emery Brown's lab at MIT in 2014. I am now based at the Athinoula A. Martinos Center for Biomedical Imaging at Massachusetts General Hospital, supported by a K99 award from the NIH.
