Biography

Julie Chang has worked at the Oklahoma Geological Survey as a Geologist since 2008, where she makes geological maps as part of the STATEMAP program.  Her love of the outdoors and physical activity led her to pursue a career in the geosciences. She has three degrees in geology: (1) a Bachelor’s from Montana State University, where she studied igneous rocks of the Absaroka Mountains, WY; (2) a Master’s from the University of Arizona, where she studied mineralization related to alkaline igneous rocks in eastern Mexico; and (3) a Ph.D. from the University of Texas at El Paso, where she studied xenoliths within the Rio Grande Rift and igneous and metamorphic rocks of the Coast Range of western British Columbia.
