Biological and Agricultural Engineering

The Department of Biological and Agricultural Engineering applies engineering principles to biologically-based systems, primarily in agriculture and the environment. The BAE department provides excellent educational opportunities at the undergraduate level with programs that are well recognized as among the finest in the United States. Two undergraduate curricula are offered:

  1. Biological Engineering (BE) and
  2. Agricultural and Environmental Technology (AET)

The BE curriculum includes concentrations in agricultural engineering, bioprocess engineering, and environmental engineering. All concentrations within the BE curriculum emphasize core courses in biology, mathematics, physics, chemistry, hydraulics, mechanics, materials, and thermodynamics, which collectively provide solid training in basic science and engineering. The curriculum is designed to prepare each graduate to master fundamentals of engineering and biology, develop the ability to solve engineering problems, improve self-confidence, and apply the creative process of engineering design. The educational experience is capped off with a two semester senior level course that immerses each graduate in the team approach to developing engineering solutions to complex problems. By the time of graduation, approximately 80% of BE graduates will have passed the Fundamentals in Engineering exam and thus be well on their way toward licensure as a Professional Engineer.

The AET combines an understanding of agricultural, biological, and physical sciences with technology and economics so that the focus is on applying engineering principles to agricultural and environmental systems. Graduates are prepared to apply and manage the use of technical tools in production agricultural and environmental issues, or in other industries interfacing with natural resources or agriculture. The AET graduates provide a critical link in the agricultural and environmental spectrum by interacting directly with the production personnel as well as designers, implementers and managers of technological systems.

Opportunities

BE students learn to solve a wide variety of engineering problems and will have opportunities for specialization though selection of a specific concentration. Scientific and engineering principles are applied: to conserve and manage air, energy, soil and water resources; to manage, protect and restore natural ecosystems; to understand and utilize biological, chemical and physical processes for the production and conversion of biomass to bio energy; to analyze, understand and utilize mechanical properties of biological materials; to design and develop machinery systems for all phases of agricultural and food production; to design and evaluate structures and environmental control systems for housing animals, plant growth, and biological product storage; to develop improved systems for processing and marketing food and agricultural products; and to design sensor-based instrumentation and control systems for biological and agricultural applications.

Graduates of the BE curriculum receive a “B.S. in Biological Engineering,” qualifying them for positions in design, development, and research in industry, government and public institutions. The curriculum also prepares students for post-graduate work leading to advanced degrees. Typical positions filled by recent BE graduates include: stream and wetlands restoration project manager; product design; development and testing engineer; plant engineering and management; engineering analysis and inspection for federal and state agencies; engineering consultant and research engineer. Entry-level salary ranges for BE graduates are similar to those of Civil, Industrial, and Mechanical Engineering graduates.

The AET curriculum provides graduates opportunities in technical analysis, application and evaluation of agricultural production systems and environmental systems. The curriculum’s flexibility enables students to specialize technologically in agriculture, the environment, or business management. Careers include technical jobs in production agriculture, environmental systems, agribusiness sales and service, and agricultural extension.

Curricula

The BE curriculum is jointly administered by the College of Agriculture and Life Sciences and the College of Engineering and combines the fields of engineering, biology and agriculture. The BE curriculum is accredited by the Engineering Accreditation Commission of ABET, Inc. BE graduates are qualified to become registered professional engineers by passing the appropriate examinations and upon completing the engineering experience requirements. Specific curriculum requirements are available online.

The program educational objectives of the Biological Engineering (BE) Bachelor of Science (B.S.) degree are to:

  • Educate students for successful careers in engineering by mastering the fundamentals of engineering and biology.
  • Instill in the students time management skills and a sense of confidence in their ability to grasp and apply engineering principles to solve complex, real-world problems.
  • Impart a sense of professional responsibility and work ethic.
  • Establish an educational environment in which students participate in interdisciplinary activities.
  • Offer a curriculum that provides students an opportunity to become broadly educated engineers and life-long learners
  • Expose students to advances in engineering practice and research.
  • Recruit students with high potential who will contribute to the future economic and social well-being of North Carolina.

The AET curriculum is administered by the College of Agriculture and Life Sciences and is intended to uniquely prepare students for hands-on application of technology to efficiently manage agricultural and environmental systems. Flexibility within the program allows students to attain depth in science, business, or environmental areas. Graduates provide a critical link in the agricultural and environmental spectrum by interacting directly with both production personnel as well as the designers and implementers of technological systems.

The program objectives of the Agricultural and Environmental Technology (AET) Bachelor of Science (B.S.) degree are to:

  • Develop in students a contextual knowledge of physical and biological systems supporting agriculture and the environment.
  • Develop a contextual knowledge of physical and biological systems supporting agriculture and the environment.
  • Develop depth and/or breadth by choosing appropriate agricultural, environmental or business electives.
  • Utilize hands-on approaches in the formulation of solutions to practical problems.
  • Apply critical thinking and existing technology to identify, evaluate, and solve problems with agricultural and environmental systems.
  • Communicate effectively between engineers, technicians, businesses, and consumers to gain information needed to solve problems and present solutions.
  • Motivate students to engage in life-long learning.
  • Work effectively in teams.

Minor in Agricultural and Environmental Technology

A minor is offered to students interested in the application of engineering technology analysis in agricultural and environmental systems that utilize machinery, agricultural structures, food and feed processing, soil, water and waste management, electrical power and controls, and agricultural safety and health technology. This minor is not open to AET majors and allows majors in other programs to understand engineering technology for equipment, materials, resources, processes, and facilities utilized in their major area of study, and be knowledgeable in the application of technology for managing environmental issues, impacts, and monitoring.
