David Barack is a neuroscientist and philosopher. His neuroscientific investigations target the neural circuits of foraging decisions in humans and non-human primates. He is particularly interested in how primates search for information, how information is encoded in the brain independently of reward, and how information guides inferences about the world. David’s philosophical work explores the conceptual foundations of cognitive neuroscience, especially the underlying dynamical basis for cognition. David received his PhD in philosophy from Duke University and worked as a postdoc at the University of Pennsylvania. He is currently a postdoctoral research fellow in the Salzman Lab at Columbia.
