John Joseph Hopfield

Research in diverse aspects of physics, including computational neurobiology and computing networks, the interaction of light with solids, impurity states in semiconductors, the proofreading for accuracy in biomolecular synthesis, electron transfer process in bioenergetics, and the kinetics of biochemical reactions. Primarily a theorist, his research has most often been in constructing the conceptual framework in which experimental results are to be understood. The current research focus is primarily involved in understanding how networks of neurons communicating with action potentials give rise to the immense 'computational power' of the brain.
