Sarah Quinn Foster

  • Assistant Professor
Academic Division: Mathematics, Analytics, Science, and Technology
Dr. Sarah Foster joined Babson in 2020 and is currently teaching Oceanography (NST1060) in the Math and Science Division. Dr. Foster's research explores the response of coastal marine ecosystems to anthropogenic changes (such as nutrient pollution and climate change) across a variety of geographic and temporal scales. Dr. Foster earned her PhD (2019) and MA (2013) from Boston University in Earth Sciences with a certificate in Biogeosciences, and her BA from Hampshire College (2006). Prior to joining Babson, Dr. Foster taught at Boston University and worked for the United States Geological Survey in Menlo Park, CA on their long-term water-quality monitoring program in San Francisco Bay. As a marine ecologist and science educator she is dedicated to sharing her love of science and ocean ecosystems to diverse groups of people through outreach programs, workshops, and classroom teaching. She is also committed to supporting increased visibility and opportunity for historically underrepresented groups in STEM and academia in general. Dr. Foster is excited to contribute to the Babson community through education and basic research that helps to build a more sustainable and regenerative future for the planet.
