David Barack is a neuroscientist and philosopher. His neuroscientific investigations target the neural circuits of foraging decisions in humans and nonhuman 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. He received his PhD in philosophy from Duke University and worked as a postdoctoral researcher at the University of Pennsylvania. He is currently a postdoctoral research fellow in the Salzman Lab at Columbia and an 2019 K99/R00 Awardee through the NIH BRAIN Initiative.
