Head: S. W. Searcy

The Department of Biological and Agricultural Engineering offers graduate studies leading to both engineering degrees and non-engineering degrees. Engineering degrees include Master of Science, Master of Engineering (non-thesis) and Doctor of Philosophy. In addition, the department offers courses and faculty supervision for students pursuing the Doctor of Engineering degree. Faculty expertise exists for study in the fields of environmental and natural resource engineering; bioprocess engineering; food engineering; biomaterial science; machine and energy systems; systems analysis; and food, feed and fiber processing. Active research programs are ongoing in all of these areas. Minimum preparation for entry into advanced study for engineering degrees would include a baccalaureate degree in engineering. Students with non-engineering degrees can be accepted into an engineering program but must complete some basic engineering prerequisite courses.

The department offers two non-engineering graduate degrees. The Master of Science in Agricultural Systems Management provides students with agricultural and business backgrounds the opportunity to pursue either a research-based or a non-thesis graduate degree in systems management techniques for agricultural industries. The Master of Agriculture in Agricultural Systems Management is technology oriented with emphasis on systems analysis and management. It requires an internship for practical experience. The faculty also participates in supervision of students pursuing Master of Science and Doctor of Philosophy degrees from interdisciplinary faculties such as Water Management and Hydrologic Sciences. Minimum preparation for entry into advanced study for non-engineering degrees would include a baccalaureate degree in Agricultural Systems Management, Food Science and Technology, or equivalent. Depending on degree and area of study, prerequisite courses may be required to provide the technology background.

Excellent research and study facilities exist which enhance all degree programs. Research facilities include modern laboratories, computer systems, testing equipment, data acquisition systems, technical support and areas for field studies. Supporting courses are available in a wide variety of disciplines as well as within the department. No foreign language is required for a PhD in Biological and Agricultural Engineering.
