For the Degree of Bachelor of Science in Agricultural and Biological Engineering

Agricultural and biological engineering is the application of mathematics, physical and biological science, and engineering to agriculture, food systems, energy, natural resources, the environment, and related biological systems. This ABET-accredited program has special emphasis on environmental protection and the biological interface of plants, animals, soils, and microorganisms with the design and performance of environments, machines, mechanisms, processes, and structures.

Concentrations

The agricultural and biological engineering program provides two concentrations: Agricultural Engineering and Biological Engineering. Each concentration has specific areas of specialization related to career interest.

Agricultural Engineering Concentration

The B.S. Degree in Agricultural and Biological Engineering provides a concentration in Agricultural Engineering. This concentration includes the integration of physical and biological sciences as a foundation for engineering applications in agriculture, food systems, energy, natural resources, the environment, and related biological systems. Students pursuing this concentration are involved in the design of systems for renewable energy, off-road equipment, water quality, and the utilization and protection of soil and water resources. Important design constraints are economics, conservation of materials and energy, safety, and environmental quality. Within this concentration, students are strongly encouraged to select a set of coherent courses that constitutes a specialization in their area of career interest either from the following list or a customized area  chosen in consultation with an advisor:

  • Renewable Energy Systems
  • Off-Road Equipment Engineering
  • Soil and Water Resources Engineering

Biological Engineering Concentration

The B.S. Degree in Agricultural and Biological Engineering also provides a concentration in Biological Engineering. This concentration integrates biology and engineering to provide solutions to problems related to living systems (plants, animals, and microorganisms). Engineered biological systems vary widely in scale. At the molecular level, nanometer-scale devices consist of a few biomolecules inside individual cells. At the other extreme, regionally-scaled complex ecosystems depend upon multiple species of interacting living organisms. Such systems are becoming increasingly important in areas such as bioenergy, bioprocessing, nanotechnology, biosensing, bio-informatics, and bioenvironment. Within this concentration, students are strongly encouraged to select a set of coherent courses that constitutes a specialization in their area of career interest either from the following list or a customized area chosen in consultation with an advisor:

  • Bioenvironmental Engineering
  • Ecological Engineering
  • Food and Bioprocess Engineering
  • Nanoscale Biological Engineering
