Biography

Sarah Rosengard is an ocean scientist and Lecturer in the School of Environmental Science at ´óÏó´«Ã½. Originally from Queens, New York, she has had the privilege to learn and grow from researchers and community leaders spanning New England to Vancouver, and the Amazon River Basin to the Canadian Arctic. Since completing her PhD in ocean carbon cycling at MIT-Woods Hole Oceanographic Institution, she has pursued deeper interests in community engagement through research by working for or collaborating with organizations like the Arctic Eider Society, Friends of the Chicago River, and Teens Take on Climate. Over the past five years, she was a professor at the School of the Art Institute of Chicago, where she researched the local geochemistry of the Chicago River, and explored the role of art in environmental knowledge production and science education. She once lived in Vancouver as a postdoctoral fellow at the University of British Columbia, and is excited to return to the region now as an environmental science lecturer at ´óÏó´«Ã½. While Sarah has had experiences supporting research and field work on a global scale, she is eager to use her time at ´óÏó´«Ã½ to understand what it means to conduct research at a more local scale, learn from the communities around us, and contribute to a curriculum for urban environmental science within the School.
