I am a geophysical and environmental scientist. My research focuses on how rivers form and co-evolve with landscapes. I have particular interest in mountain rivers and cold regions of the Arctic. I use field campaigns, physical experiments and theory development to address basic research questions. I apply my research to improve how professional scientists approach and develop river restoration plans, including the removal of dams. I also have two decades of professional experience as a consulting river scientist and geomorphologist, working throughout California and southern Oregon.
