Dr. Hector M. Menendez III received his Ph.D. from South Dakota State University in Biological Sciences (2018). In 2020, he joined SDSU as an Assistant Professor in the Animal Science Department and serves as a state Livestock Grazing Extension Specialist. Dr. Menendez’s research is focused on understanding complex grazing systems and identifying high-leverage solutions. He accomplishes this by using a combination of mathematical simulation modeling, precision livestock technology, and through the evaluation of water-soil-plant-animal interconnections. Dr. Menendez’s Extension programming applies a systems approach to enhance producer management of livestock grazing systems. He also serves as a committee member of the National Animal Nutrition Program, which guides national nutrient modeling resources, training, and application.
