Biological Systems Engineering, Bachelor of Science College of Engineering

The Biological Systems Engineering Undergraduate Program

Biological Systems Engineering is an engineering major that uses life sciences as its main scientific base. With rapid advances in biology and biotechnology, engineers are needed to work side by side with life scientists to bring laboratory developments into commercial production or field application. Industries in food and fiber production, bioenergy, bioprocessing, biotechnology, food processing, agriculture, forestry, aquaculture, plant and animal production, natural resource management, and waste reduction all need engineers with strong training in biology. In the first two years, the Biological Systems Engineering major requires sequences of courses in mathematics, physics, chemistry, engineering science, and humanities, similar to all accredited engineering programs. In addition to these courses, the major also includes courses in the life sciences and the application to engineering. Exclusive of General Education units, the Biological Systems Engineering major requires a minimum of 163 units (86 units in the lower division; 77 units in the upper division).

Biological Systems Engineering graduates take jobs in biotechnology, energy, food, and medical industries, work for federal, state and local agencies, and pursue graduate work. Students can also use the program as a pathway to professional schools in medicine, veterinary medicine, education, law, or business.

The Biological Systems Engineering program is accredited by the Engineering Accreditation Commission of ABET.

Students are encouraged to adhere carefully to all prerequisite requirements. The instructor is authorized to drop students from a course for which stated prerequisites have not been completed.

Areas of Specialization

Biotechnical Engineering

Biotechnology involves the handling and manipulation of living organisms or their components to produce useful products. Students specializing in biotechnical engineering integrate analysis and design with applied biology to solve problems in renewable energy production, bioprocessing, control of biological systems, and production of biomaterials and bioproducts.

Students may focus on the mechanisms and processes for the sustainable production and use of energy from renewable biological sources. Students may also focus on the challenges in scaling up laboratory developments to industrial production, including production, packaging, and application of biocontrol agents for plant pests and diseases; genetically altered plants; plant materials and food products; and microbial production of biological products, tissue culture, and bioremediation. Students may also focus on the development of biosensors to detect microorganisms and specific substances useful in the development of products based on biological processes and materials.

Biotechnical engineers work in the biotech industries on process design and operation, scale-up, and instrumentation, sensing, automation, and control.

Agricultural & Natural Resources Engineering

With the world population continuing to grow over the next several decades, grand challenges exist in food security and social, economic, and environmental sustainability. Meeting the needs of agriculture and the effective use of natural resources will require continuing innovation. Students specializing in agricultural and natural resources engineering combine analysis and design with applied biology to solve problems in producing, transporting, and processing biological products to provide food, fiber, energy, pharmaceuticals, and other human needs.

Students may focus on automation and control of field operations and engineered systems, robotics, and the biomechanics of humans and animals. They may also focus on engineering issues related to the sustainable use of natural resources, particularly energy and water, but also land and air.

Agricultural and natural resources engineers are employed as practicing professionals and managers with agricultural producers, equipment manufacturers, irrigation districts, food processors, consulting engineering firms, start-up companies, and government agencies. Graduates with interest in biomechanics work in industry on the design, evaluation, and application of human-centered devices and systems, as well as on improving worker health and safety.

Food Engineering

Producing the food we eat every day constitutes the largest industrial sector of the U.S. economy, and this production involves the work of engineers in a wide variety of food industries, both at home and around the world.  Students specializing in food engineering design food processes and operate equipment and facilities for production of high quality, safe, and nutritious food with minimal impact of these operations on the environment.

Students learn to apply engineering principles and concepts to handle, store, process, package, and distribute food and related products. In addition to engineering principles, the food engineering specialization provides an understanding of the chemical, biochemical, microbiological, and physical characteristics of food. Students study concepts of food refrigeration, freezing, thermal processing, drying, and other food operations, food digestion, and health and nutrition in food system design.

Food engineers work as practicing engineers, scientists, and managers in the food industry.
