Erik Johanson

Dr. Erik Johanson is an Associate Professor in the Department of Geosciences at Florida Atlantic University. His research focuses on environmental change and human-environment interactions, particularly in the tropics, using sedimentary proxies like isotopes, pollen, and microplastics to inform ecological management and future climate predictions.

• Education:
  • Ph.D. in Geography, University of Tennessee (2016)
  • M.A. in Anthropology, University of Tennessee (2011)
  • B.A. in Anthropology, University of Tennessee (2008)

Dr. Johanson’s research explores fire histories, agricultural dissemination, societal resilience to droughts, and microplastics' environmental impacts. His lab collects sediment cores from Central/South America, the Caribbean, and Florida. Recent publications highlight multiproxy analyses in cypress swamps, post-conquest ecological changes in Costa Rica, and Manteño agricultural adaptations in Ecuador.

He teaches courses on climate change, paleoenvironmental reconstruction, and human-environment interactions. Media coverage includes topics on Florida heatwaves and hurricane preparedness. His Environmental Change Lab maintains active social media profiles on Instagram and Facebook.
