Professor Ermias Kebreab
Professor Ermias Kebreab is Associate Dean of Global Engagement in the College of Agricultural and Environmental Sciences at the University of California, Davis, where he also serves as Director of the World Food Center and holds the Sesnon Endowed Chair in Sustainable Animal Agriculture. His research focuses on developing climate smart livestock systems through advances in animal nutrition, mechanistic modeling, and sustainable food production.
Professor Kebreab is internationally recognized for his work on reducing greenhouse gas emissions from livestock, particularly enteric methane emissions from ruminants. His research integrates nutrition, microbiology, systems modeling, artificial intelligence, and life cycle assessment to develop practical solutions that improve productivity while reducing environmental impacts. His laboratory has pioneered research on methane mitigating feed additives, precision feeding systems, and mechanistic models used to evaluate livestock sustainability.
He has authored more than 300 peer reviewed publications and has served on numerous international scientific and policy initiatives related to climate change, livestock systems, and sustainable agriculture, including collaborations with FAO, the IPCC, and global research networks. His work has contributed to the development of climate mitigation strategies and decision support tools for livestock systems across North America, Asia, Africa, and Latin America. Professor Kebreab delivered a TED Talk which has received more than 2 million views globally and helped bring scientific discussion on livestock methane mitigation to a broader public audience.
He is a Fellow of the American Dairy Science Association (ADSA) and has received multiple international awards recognizing his contributions to animal science, sustainability, and global food systems. He is widely invited as a keynote speaker at major international conferences on sustainable livestock production and climate smart agriculture.
