Research Overview

Jeff has been involved in basic and applied rivers research in a variety of river ecosystems worldwide, including dam removal in Fossil Creek, Arizona; wetland mitigation in North Carolina; food web studies on the Danube River in Austria/Hungary/Serbia and glacially-fed rivers in Italy; and large dam impacts on the Colorado River.
