Timothy T. Rogers is a professor of Psychology at the University of Wisconsin-Madison. He received his Ph.D. from Carnegie Mellon University. He is interested in understanding human semantic memory; that is knowledge about the meanings of words, objects, and events. Specifically, He would like to understand how semantic knowledge is stored and represented in the mind and brain, how it is acquired throughout development, how semantic tasks are performed by healthy adults and experts, and how semantic knowledge degrades in dementia.
