Rebecca Ryals

Rebecca Ryals is an Associate Professor in the Department of Life and Environmental Sciences at the University of California, Merced. She holds a PhD in Environmental Science, Policy, and Management from UC Berkeley (2012), an M.E.M. in Ecosystem Science and Management from Duke University (2006), and a B.Sc. in Environmental Science from Marywood University (2004).

Her research program examines agroecosystem sustainability through three interconnected themes: regenerative agriculture practices that enhance soil health; ecological sanitation systems that recycle organic waste streams; and climate change mitigation strategies focusing on carbon sequestration and greenhouse gas dynamics.

Recent publications (2023-2024) demonstrate consistent investigation of organic soil amendments (compost, biochar) across diverse agricultural systems, with emphasis on carbon dynamics, nutrient cycling, and emission reductions. Research frequently bridges sanitation waste management with agricultural productivity improvements.

Leads the Agroecology Lab investigating sustainable agriculture solutions through ecological approaches. Current projects examine compost application in rangelands, orchards, and urban parks to enhance soil carbon storage while reducing environmental impacts.
