Agricultural Mechanics: Fundamentals & Applications

Author

Ray V. Herren

Ray V. Herren has been actively involved in agriculture for most of his life. He grew up on a diversified farm, where he played a major role in the production of livestock. He obtained a bachelor of science degree in agricultural education from Auburn University, a master's degree in agribusiness education from Alabama A & M, and a Doctorate in Vocational Education (with an emphasis in agricultural education) from Virginia Polytechnic Institute and State University. Dr. Herren has taught at Virginia Tech, Oregon State University, and the University of Georgia in Athens, where he recently retired as head of the Department of Agriculture Leadership, Education, and Communication. In addition to serving as a national leader in the Future Farmers of America (FFA) alumni organization, he has served on numerous committees from the local to international level, including a national task force to develop FFA programs for middle school and the national committee for career development events. His prolific scholarly activity includes 26 journal articles, 51 invited or refereed presentations, and 12 books and manuals. He has also earned several awards for his commitment to service, as well as UGA's prestigious College of Education Outstanding Teaching Award.
