Jason Rech

My research interests are primarily in surficial processes of streams, wetlands and soils, geoarchaeology, and in terrestial records of climate and environmental change. I love field work, enjoy geochronology, geochemistry, and stable isotopes, and like any method or technique that will help me answer my research questions. I especially enjoy working in deserts, and have continuing research in the Middle East and the Atacama Desert of northern Chile, yet also like working close to home in Ohio on streams and wetlands.
