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.
