Jon D. Pelletier, PhD

Professor, Geosciences

Erosion is driven by the shear stress of wind and water acting on Earth’s surface. Prof. Pelletier’s work seeks to quantify such shear stresses and their impacts on the evolution of complex landscapes using field measurements, analyses of digital data, and mathematical modeling.
