    Leslie Tolbert Ph.D. Dept. of Neuroscience University of Arizona
    May 5 2026
    Leslie Tolbert spent most of her career studying neuroscience and the mysteries of the brain, which makes her frank discussion about a recent Alzheimer’s disease diagnosis all the more interesting. Tolbert received her Ph.D. in Anatomy from Harvard in 1978; in 1987 she arrived at the University of Arizona where she has held several positions including Professor, Acting Director of the Arizona Research Laboratories, Senior Vice President for Research and Regents’ Professor, among others. In this discussion Tolbert tells Tom McNamara how being exposed to different cultures at a young age expanded her mind, how she fell in love with the brain and her husband at the same time, and how after years of studying there is still so much to learn about the human brain.
