Patricia Smith Churchland is professor of philosophy at the University of California at San Diego (UCSD), where she focuses on the foundations of neuroscience and psychology. She has written extensively on how empirical research in these sciences helps to solve, or to restructure, traditional problems in the philosophy of mind, and to explore the changes in our self-conception that such research may provoke. Her books include: Neurophilosophy: Toward a Unified Science of the Mind-Brain; The Computational Brain; and The Mind-Brain Continuum.
