Katy Barnhart is a geomorphologist interested in the evolution of landscapes and the physical processes that make and move sediment. Her work combines numerical modeling, field observations, and the development of new methods of model-data comparison. Her work covers many geomorphic regions—from Arctic coasts to steep mountainous hillsides—and a wide range of timescales—from seconds to millions of years. She is also involved in the development of scientific software and is interested in developing best practices for reproducible research.
