JEFFREY ANDERSON pursued graduate studies in abstract mathematics before receiving his MD and PhD degrees from Northwestern University in neurobiology. In his education, he had formal concentrations in chemistry, physics, psychology, Russian literature, and molecular biology. His research on the brain has been published in Science, Nature Neuroscience, and Neuron, among other publications. He is currently a neuroradiology fellow at the University of Utah, and runs a brain imaging laboratory where he uses functional MRI to study multiple sclerosis as well as the basic science of attention, emotion, and visual imagery. He lives in Salt Lake City with his wife and their four small entropy machines.
