Tulsa, Oklahoma – On today's show, we meet the well-regarded (and recently retired) scientist Dr. Tanya Atwater. She's an American geophysicist and marine geologist who specializes in plate tectonics, and in particular the evolution of the San Andreas fault plate boundary. (Indeed, her specialty is the plate tectonics of the American West, and especially California.) She's also a great and avid proponent of science education at all levels. Dr. Atwater is giving a free, open-to-the-public lecture on the TU campus today (at noon; in Keplinger Hall) entitled "Cenozoic Plate Tectonics in the Western United States: From Subduction to the San Andreas Fault." And as we learn from her compelling yet accessible discussion with our host Rich Fisher, Dr. Atwater, moreover, has long been a pioneer not only in the realms of geology and plate tectonics --- but also in the area of women's professional careers in science.
