2023 Speakers


Dr. Randie Culbertson

Originally from New Mexico, Randie Culbertson spent her childhood on the family's cattle ranch located in Norther New Mexico. She later attended New Mexico State University where she obtained a B. S. in Animal Science. After completing her degree at NMSU, she moved to Colorado where she worked in the equine industry for a little over 10 years. In 2011, she pursued her graduate degrees at Colorado State University where she earned her M. S. and Ph. D. in Animal Breeding and Genetics. While pursuing her graduate degrees, Randie's research interests focused on addressing questions facing the beef industry. Her doctoral research focused on feed intake in beef cattle and specifically the implementation for genetic improvement. The last 9 months at CSU, Randie managed and coordinated a USDA grant project examining late feedlot death in cattle. This project examined the effects of pulmonary arterial pressure (PAP) on the performance and survivability of fed steers and begins to answer some questions about this growing concern. Upon completing her Ph. D. in 2019, she accepted a position as lead geneticist with the American Simmental Association and International Genetic Solutions (IGS) where she worked on challenges to conducting the largest multi-breed genetic evaluation for beef cattle and was involved in the development and validation of new EPDs. Last November, Randie joined the faculty at Iowa State University as the Cow-Calf Extension Specialist.
