Geographers on the Market: Joanne Ballard


Joanne Ballard

Department of Geography
University of Tennessee



Joanne graduated in August 2015 with a PhD in Geography. Sally Horn was her advisor.

Joanne has expertise in Quaternary environments and biogeography. She analyzes lake sediments for geochemical, geological, pollen, charcoal, and other evidence, and compare to ice core data to reconstruct past environments and events.

She also studies the paleontological record for geochemical evidence.   Geochemical analyses include stable isotopes, Xray fluorescence, Xray diffraction, thin sections, and experiments. She has developed a new proxy for paleofire, which may revolutionize paleoclimate studies, particularly for catastrophic events. Furthermore, she also has  experience in  glacial geology, dendrochronology, hydrology, soils, and field botany.  She has conducted research in eastern North America and western Europe and collaborates across disciplines.
