Ann Petersen  has a B.S. in Marine Science from Eckerd College and a Ph.D. in Integrative Physiology from CU Boulder. Dr. Petersen is fascinated by how animals develop and survive in environmentally challenging conditions that arise from natural habitat conditions or from human introduced pollution. Her students examine questions in developmental biology, ecotoxicology, wildlife disease, genetics, and endocrinology.

Prior to arriving at OSU-Cascades, Dr. Petersen was a member of an NIH funded project team at University of Oregon examining how the common aquatic pollutant perchlorate affects health and development in stickleback fish. Dr. Petersen's research has been published in the Journal of Experimental Biology, PLOS One, General and Comparative Endocrinology, and is the 2016 Chair of the Gordon Research Seminar on Environmental Endocrine Disruptors. As a faculty member at OSU-Cascades, Ann and her students will examine the effects of water quality on health and development of wild populations of stickleback fish in the Deschutes and John Day Rivers, as an indicator of effects of human pollution on all vertebrates exposed to the water, including humans.
