Welcome to our group’s homepage. We study the hydrology, geomorphology, and biogeochemistry of landscapes and river systems and their links with humans and ecosystems.

Our group is part of the Department of Civil & Environmental Engineering (CEE) at Vanderbilt University. CEE is a multidisciplinary department with faculty specializing in Energy and Natural Resources; Risk, Reliability, and Resilience; Big Data Science; and Nanoscale Science and Engineering.
