# overview
William Pinchak, Ph.D., is a professor with the Texas A&M Agrilife Research and Extension Center at Vernon. Pinchak joined the Texas A&M Agrilife Research and Extension Center in 1984. His research approach focuses on sustainable production of animal protein from agricultural ecosystems. The research program adopts a "soil to sirloin" or "pasture to plate perspective," where the sustainability of entire systems from soil conservation to animal production is a key focus. Current beef cattle systems biology research focuses on integrating molecular genomics of cattle and their gut bacteria with the latest advances in protein and metabolism measurements with economically relevant traits such as feed efficiency, animal metabolic disorders, bovine respiratory disease, antimicrobial resistance, methane production and food safety.
