معرفی
Jon Pelletier is a Professor in the Department of Geosciences at the University of Arizona, College of Science. His research centers on geomorphology, focusing on how landforms are shaped by rivers, glaciers, wind, and climate. He integrates computer modeling with field and remote-sensing data to understand surface processes and their feedbacks with fluid flows.

Dr. Pelletier’s research interests span geomorphology, surface processes, critical zone science, and planetary landforms. He investigates how fluid dynamics shape Earth’s surface through fluvial, aeolian, and glacial processes. His work emphasizes numerical modeling, landscape evolution, soil formation, and the interaction between climate, tectonics, and topography. He also explores applications to Mars and other planetary bodies.
His recent publications reveal a strong focus on drainage networks, soil-landscape coevolution, aeolian dynamics, critical zone architecture, and modeling of Earth and planetary surfaces. Key themes include the role of aspect and insolation in weathering, post-wildfire erosion, hillslope hydrology, and the calibration of land surface models. His work often bridges field observations with computational simulations.
Dr. Pelletier has contributed to major modeling frameworks such as the Community Land Model and has led or participated in large-scale experimental projects like the Landscape Evolution Observatory at Biosphere 2. His research integrates hydrology, biogeochemistry, and ecology in understanding Earth surface dynamics.
He teaches courses in geomorphology, including Geos 450/550: Introduction to Geomorphology, and mentors students in surface process research. His laboratory supports modeling and data analysis for geomorphic applications.
