In the Pesaran Lab, Greg studied speech perception and production, characterizing the dorsal stream for auditory speech processing. His specific focus is on how the brain transforms between representations that are specific to perception (sensory) and representations that are specific to production (motor). He is also interested in how this transformation relates to other speech computations such as lexical access and verbal working memory. Prior to joining the lab, Greg completed a PhD in Neural and Cognitive Sciences at the University of Maryland with David Poeppel. Greg is now working with Jon Viventi at Duke University to continue his work studying speech processing in humans with advanced brain interfaces.
