Joanna Carey

  • Associate Professor
  • Debi and Andy Butler Term Chair
Academic Division: Mathematics, Analytics, Science, and Technology


Dr. Carey joined Babson in 2017 as an Assistant Professor in the Math & Science Division. She currently teaches Case Studies in Ecological Management (NST 2020), and Oceanography (NST 1060). Her research focuses on answering fundamental questions regarding ecosystem processes in the context of rapid global change. She examines how human activities are altering carbon, nitrogen, and silicon cycling along the land-ocean continuum (forests, rivers, salt marshes, and estuaries) in temperate and Arctic ecosystems. Dr. Carey received her Ph.D. in Earth Science from Boston University (2013), her M.S. in Environmental Science from Yale University (2007), and her B.S. in Environmental Policy & Planning from Virginia Tech (2005). Before joining Babson in 2017, Dr. Carey completed several post-doctoral fellowships, including an NSF Earth Science Fellowship and a USGS Powell Center Fellowship, both hosted at the Marine Biological Laboratory in Woods Hole, MA.
