Ginna attended Carleton College in Minnesota and later received her Ph.D. in economic geology at the University of California, Berkeley. She worked as an exploration geologist for eight years, principally with Anaconda Minerals Company in Nevada, Utah, and Alaska, but also for Amax, Kennecott, Freeport, and Noranda Exploration, mostly in the Basin and Range. Dr. Gillerman counts gold deposits, skarns, base metal replacement deposits, petrology, structural geology, and detailed mapping as her specialties within a wide range of geologic experience. As a geologist with the Idaho Geological Survey, Ginna provides information to the public and government agencies on a wide diversity of geologic issues affecting southern Idaho. She monitors and reports on mining and exploration activity in Idaho and occasionally teaches an @Ore Deposits@ class at Boise State University. With the IGS, she has also worked on a number of field-oriented projects, including geologic mapping of Jerome County, hazard inventories of historic and inactive mine sites, landslide evaluations, and educational programs.
