Dr. Johanson studies human-environment interaction and environmental change across the Holocene. His interests center around how people shape their environments and manage climate stress in the tropics over the last several thousand years often by examining sedimentary archives (isotopes, pollen, charcoal, diatoms, geoarchaeolgy). With a background in geography and anthropology, many of his studies look to the past to inform the present. Research topics include pre- and post-maize agricultural fire histories, the timing and pathways for the dissemination of key agricultural domesticates, resilience and societal response to mega droughts and environmental change, historical ecology of the tropics, the development of paleoclimate records, and the impact and modeling of future climate change. Dr. Johanson's Environmental Change Laboratory often collects and analyzes sediment cores from lakes and wetlands in Central and South America, the Caribbean, and Florida.
