Christian is a fluvial geomorphologist who uses geomorphic history, sediment transport models, and hydraulics to better understand channel and floodplain dynamics. Christian likes to tackle problems with implications for aquatic habitat and questions that feature feedbacks between physical and biological processes. He has worked on topics ranging from stream restoration in steep, confined channels to assessing the impacts of dam removal. His Ph.D. dissertation used physical models to explore the conditions required for rivers to meander and how gravel-bed meanders respond to changes in sediment supply.
