Erik Johanson, PhD student in the Department of Geography, has received a grant from the Geological Society of America to support his dissertation research on climate change and prehistoric human-environment interaction in southern Pacific Costa Rica.
Johanson also received grants from two interest groups within the Association of American Geographers, the Biogeography Specialty Group and the Paleoenvironmental Change Specialty Group, and from the Stewart F. McCroskey Fund at the University of Tennessee. These funds will support the collection of lake sediment cores in Costa Rica, and the analysis of pollen grains, charcoal fragments, stable carbon isotope signatures, and other sedimentary components that provide evidence of past climate and prehistoric agriculture in lake basins.
His PhD work is advised by Sally Horn. Prior to entering the UT Geography Department, Johanson completed an MA degree in anthropology, with a thesis on spatial modeling of archaeological site distribution in Louisiana.
