Our
Collaboration
Composting for Healthier Communities
Researchers, students, and faculty from the University of California, Merced partnered with Central Valley organizations to establish community composting systems and develop community-engaged composting resources.
Community Partners
CCEJN's mission is to empower Central Valley communities and secure our children's future by eliminating negative environmental impacts in low income and communities of color.
The Wukchumni Tribe 501c3 is dedicated to revitalizing and maintaining the cultural values (traditional and spiritual) of the Wukchumni Yokuts.
FoodLink for Tulare County aims to promote equitable and dignified access to nutritious, healthy food while also addressing the root causes of hunger through education, advocacy, and food systems change.
Meet The Team
Associate Professor of Agroecology & Presidential Chair in Climate Change
University of California, Merced
Rebecca Ryals
Rebecca leads the Agroecology Lab at UC Merced, which studies how nutrients and
carbon cycle in agroecosystems, and how the management of these cycles contributes to
climate change mitigation and resiliency. A major research theme in her lab is the capture,
transformation, and beneficial reuse of organic resources to rebuild soil carbon and contribute to
a more productive and just food system.
Associate Professor
University of California, Merced
Teamrat A Ghezzehei
Teamrat leads the Soil Physics and Hydrology Lab at UC Merced, which studies how water, nutrients, and energy move through soil and how this influences plant growth, environmental health, and sustainable agriculture. A major research theme in his lab is
understanding the physical properties that make soil habitable for organisms and how this knowledge can be applied to develop farming practices that are more efficient, resilient, and environmentally friendly.
Assistant Professor of Cooperative Extension & Specialist, Regenerative Agriculture
University of California Agriculture and Natural Resources (UCANR) & UC Merced
Srabani Das
Srabani’s areas of expertise are soil health and agricultural soil carbon. Her research
focuses on analyzing the influence of organic amendments, tillage systems, cover cropping and
irrigation methods on soil health. She aims to develop tools for tracking soil carbon buildup from
different practices of regenerative agriculture and make their access equitable for all grower
communities, including the marginalized and BIPOC (Black, Indigenous, People of Color).
Associate Professor of Public Health Communication University of California, Merced
Susana Ramirez
Dr. Susana Ramírez is a nationally recognized expert in media, inequality, and health. As an “infodemiologist”—trained in both communication and public health—Dr. Ramírez uses social scientific methods to advance public health goals. Her research aims to advance understanding of how the public information environment contributes to population health through policy agenda-setting, community action, and individual decision-making. A longstanding line of research considers the role of the public information environment on health outcomes and upends traditional behavioral research that (mis)characterizes Latinos, immigrants, and African Americans as having cultural orientations in opposition to healthy lifestyles. Rather, Dr. Ramírez’ findings provide a narrative for how communication may impact health disparities. Recent research extends this theorizing to advance understanding of the corporate and commercial determinants of health, including elaboration of a theoretical framework for racialized marketing.
