biogeochemistry, soil sustainability, carbon, nitrogen, water cycling, synthetic biology


The Masiello research group focuses on carbon, nitrogen, and water cycles in the Earth system. We are particularly interested in the development of new techniques to study carbon and nitrogen cycling in soils, sediments, the atmosphere, and water.
