Dr. Luke McGuire's Surface Processes Research Group at the University of Arizona studies problems in Earth surface processes across a wide range of scales, from sediment transport during individual rainstorms to soil development and transport over millions of years. We use a variety of tools and methods, including field-based studies, numerical modeling, and remote sensing, to understand how landscapes evolve.Show Less
