Hannah Cunningham Hollinger

Hannah Cunningham Hollinger is an Assistant Professor of Animal Genetics in the Department of Animal Science at the University of Wyoming. Her research focuses on improving ruminant livestock productivity through maternal-fetal interface mechanisms, with a specialization in rumen microbiome development and its long-term impacts on feed efficiency.

• Education: B.A. in Biology (St. Olaf College), M.S. in Animal Science - Ruminant Nutrition (University of Wyoming), Ph.D. in Animal Science - Animal Genetics (University of Wyoming).

Hollinger's research integrates animal genetics, nutrition, and reproductive biology to explore:

• Rumen microbiome development timelines
• Maternal influences (microbiome, nutrition) on offspring microbiomes
• Long-term productivity impacts of early microbiome establishment
• Milk microbiome connections to subclinical mastitis in sheep

Her work spans cross-disciplinary collaborations analyzing genetic markers, microbial ecosystems, and production metrics in cattle and sheep systems.
