Our lab’s research focuses on experimental and computational approaches to understanding the neural correlates of consciousness in humans—specifically how sleep affects the brain. We specialize in using the state-of-the-art in quantitative approaches to develop novel statistical signal processing algorithms for the analysis of neural data, with direct applications to basic science, biomarker discovery, and medical device development.
