معرفی
Jon D. Pelletier is a Professor in the Department of Geosciences at the University of Arizona. He specializes in geomorphology, landscape evolution modeling, and critical zone processes, focusing on interactions between climate, tectonics, and surface processes. His research integrates field observations, numerical modeling, and remote sensing to understand Earth surface dynamics. Pelletier has taught courses such as 'Earth Surface Processes,' 'Geomorphology,' and 'National Parks' since 2015, reflecting his engagement with both education and applied geosciences.
His research explores topics like soil production, hillslope hydrology, aeolian dune evolution, and the impact of climate change on landscapes. He co-leads projects at the Jemez River Basin Critical Zone Observatory, investigating coupled biogeochemical and hydrological processes. Pelletier received the GSA Fellow award in 2015 for his contributions to geomorphology.
Pelletier's work bridges geology, hydrology, and ecology, emphasizing interdisciplinary approaches. Key contributions include modeling landscape evolution, analyzing soil chronosequences, and quantifying geomorphic responses to wildfires. His studies have advanced understanding of fluvial systems, pediment formation, and the role of snowmelt in shaping mountain landscapes.
