Ann Petersen

Fisheries Biologist III


  • B.S., Marine Science, Eckerd College
  • Ph.D., Integrative Physiology, Colorado University Boulder


Ann is a broadly-trained integrative physiologist focusing on effects of environmental endocrine disruptors on fish health. She has 20 years of experience working as an experimental biologist in academia and for state and federal agencies. Her work at the Northeast Fisheries Science Center’s James J. Howard Marine Sciences Laboratory looks at the effects of climate change, pollution, and habitat loss on the health of fish and fish populations. To do this she uses molecular, cellular, and organism-level experimental biology techniques. Before coming to the Howard Marine Science Laboratory, she was a postdoctoral researcher and instructor for the Oregon University system. Her work there focused on understanding the impacts of contaminants on early development, gene expression, and reproduction in the aquatic model organisms:  the stickleback and the zebrafish.
