Graduate Faculty Directory
Graduate students work together with faculty and staff to conduct a broad spectrum of research, ranging from fundamental laboratory studies to farm-oriented applied projects. These are an important component of the interaction and collaboration among researchers within the Animal Sciences Graduate Program and with faculty and students of other programs.
Graduate students are also an integral part of the teaching and extension activities of the department. These activities are vital to the development of methods and programs that will continue to improve the productivity and efficiency of animal agriculture in the state, nation, and world.
