Soil Sciences, Soil Genesis and Classification, and Advanced Pedology and Geomorphology
Faculty in Environmental Studies and Geography Departments
- Ph.D., University of Arizona
- Docteur Honoris Causa from the Faculte Des Sciences, Universite Caltholique de Louvain, Louvain-la-Neuve, Belgium
Dr. Chadwick is a joint professor in the Geography Department and Environmental Studies Program at UCSB. His work is in the areas of soil sciences, soil genesis and classification, advanced pedology, and soil geomorphology.
Dr. Chadwick has established himself as a leader in soil science, and is one of the world leaders in relating soils to ecology and earth system science. He has become of the core members of a small but growing and extremely high quality group in ecosystem studies at UCSB. His recently published paper in Nature, and international journal of science, focuses on his ten year research that utilizes Hawaii as a model ecosystem to understand changes in the sources of nutrients to rainforests.
Dr. Chadwick's research interests include pedology, soil geomorphology, soil geochemistry, quaternary geology, organic and mineral fluxes during soil, atmosphere, water and vegetation interaction. He has clearly established himself as a leader in soil science, and is one of the world leaders in relating soils to ecology and earth system science. Professor Chadwick has become one of the core members of a small, but growing and extremely high quality group in ecosystem studies at UCSB.
