About

Dr. Rivka Fidel teaches soil and critical zone science classes in the Department of Environmental Science. Her research combines Environmental Science, Soil Science and Surface Chemistry and focuses on the effects of biochar on the C and N cycles, including the sorption of C and N compounds to biochars, and effects on soil greenhouse gas emissions. She is also researching pedagogical techniques for introductory level classes in Soil Science and Critical Zone Science.
