Josh West

Josh West is a Professor in the Department of Earth Sciences at the University of Southern California (USC), affiliated with the USC Environmental Studies Program. His research focuses on the interplay between Earth's landscapes, water resources, and the carbon cycle, particularly in mountainous regions. He explores how tectonics, climate, and erosion shape topography, influence sediment and nutrient fluxes, and impact global biogeochemical cycles. Notable areas of study include Himalayan erosion dynamics, permafrost thaw effects, and the role of landslides in carbon cycle feedbacks.

West leads a research group emphasizing equity and inclusion, mentoring undergraduate and graduate students. His work integrates field observations, geochemical analyses, and modeling to address questions about Earth's long-term habitability and environmental sustainability. Key contributions include studies on the 2021 Melamchi Flood, mercury mobilization in Arctic regions, and lithium isotope tracers for weathering processes.
