Anita Lizzie Grunder is an American geologist known for her research on volcanic rocks and defining changes in volcanism over geologic eras. She is an elected fellow of the Geological Society of America.
Grunder has an A.B. in paleontology from the University of California, Berkeley (1977),[1] and subsequently worked as a field assistant at UC Berkeley, the University of California, Los Angeles, Scripps Institution of Oceanography,[2] and the United States Geological Survey.[3] She went to Stanford University for graduate school[4] where she described her position as an "adventure" in a 1983 magazine article.[3] She graduated in 1986 with a thesis project working on the geology of the southern Andes.[5] Grunder moved to Oregon in 1986, ultimately becoming a professor[2] and an associate dean.[6] As of 2019, Grunder is professor emeritus at Oregon State.[1]
Research
Grunder is a field geologist who has worked on volcanoes and volcanic rocks in a variety of locations including Nevada,[7] Oregon,[8][9] and the Aucanquilcha region in Chile.[10] Her early research was on the volcanic rocks[11][12] and hydrothermal system[13] at Calabozos crater in the Chilean Andes. She uses oxygen-18 isotopes in different types of rocks to reveal changes in magmatic activity over millions of years.[7][12] In 2005, Grunder co-edited a collection of articles on welding processes in volcanic systems,[14] and contributed an article on welded pyroclastic deposits from Oregon.[15] In Hawaii, she worked on the sulfur dioxide released by the Kilauea volcano and collaborated with a graduate student working in public health, Bernadette Longo, to reveal increased health issues for people living downwind of the volcano.[16][17] In 2020 she examined the geology of the volcanic material in the area surrounding Steens Mountain in southeastern Oregon.[18] One of her students described her skills at explaining volcanic processes and noted that she is adept at making geology interesting to a range of people, both inside and outside academia.[19]
