Our guest on this edition of ST is the acclaimed science writer, biologist, and neuroscientist, Dr. Robert Sapolsky. He's widely seen as one of our leading experts on stress --- namely, on the ways in which stress affects baboons and other primates, and what this in turn tells us about the effects of stress on the human condition. A professor of biology and neurology at Stanford University, a MacArthur "Genius" Fellow, and an author whose works include such popular books as "A Primate's Memoir" and "Why Zebras Don't Get Ulcers," Dr. Sapolsky will soon deliver the final Presidential Lecture of the current academic year on the University of Tulsa campus; his free-to-the-public address happens tomorrow night (Thursday the 4th) at 7:30pm in the Allen Chapman Activity Center. The TU Presidential Lecture Series is sponsored by the Darcy O'Brien Endowed Chair; the two earlier speakers in the 2012-13 season were Michael Tilson Thomas and Robert Caro. You'll find more about Dr. Robert Sapolsky's upcoming address here.
