Dr. Jayko is a Scientist Emeritus at the Geology, Minerals, Energy, and Geophysics Science Center at the U.C. White Mountain Research Station. She came to the USGS in 1979 and returned as an Emeritus. She studied tectonics of convergent margin associations and most recently, she’s focused on the Plio-Pleistocene transtensive deformation.
Dr. Jayko's thesis concerned Late Mesozoic subduction. She studied tectonics of convergent margin associations with work in the continental collision complex of the French Alps, in a Paleozoic transtensive basement tectonics in eastern Australia, and in the Paleozoic fold and thrust belt of central Nevada. Most recently she’s focused on the Plio-Pleistocene transtensive deformation.
