For the undergraduate curriculum in Biological Systems Engineering leading to the degree Bachelor of Science. The Biological Systems Engineering Program is accredited by the Engineering Accreditation Commission of ABET, https://www.abet.org, under the commission’s General Criteria and Program Criteria for Biological and Similarly Named Engineering Programs.
Biological Systems Engineering integrates life sciences with engineering to solve problems related to, or using, biological systems. These biological systems may include microbes, plants, animals, humans and/or ecosystems. Biological systems engineers have a worldview shaped by an understanding of fundamental principles of engineering and life-sciences. They use their understanding of engineering to analyze organisms or ecosystems, and their knowledge of biological systems to inspire and inform their designs. They approach engineering design from a biological systems perspective, appreciating the complexity of biological systems and developing solutions that accommodate and anticipate the adaptability of biological systems.
Goal: To educate students to solve problems related to biorenewables production and processing, water quality, environmental impacts of the bioeconomy, food processing, and biosensors, and in so doing to prepare students for professional practice and post-graduate educational opportunities.
Student Learning Outcomes: Graduates of the Biological Systems Engineering curriculum should have at the time of graduation:
- An ability to identify, formulate, and solve complex engineering problems by applying principles of engineering, science, and mathematics.
- An ability to apply engineering design to produce solutions that meet specified needs with consideration of public health, safety, and welfare, as well as global, cultural, social, environmental, and economic factors.
- An ability to communicate effectively with a range of audiences.
- An ability to recognize ethical and professional responsibilities in engineering situations and make informed judgments, which must consider the impact of engineering solutions in global, economic, environmental, and societal contexts.
- An ability to function effectively on a team whose members together provide leadership, create a collaborative and inclusive environment, establish goals, plan tasks, and meet objectives.
- An ability to develop and conduct appropriate experimentation, analyze and interpret data, and use engineering judgment to draw conclusions.
- An ability to acquire and apply new knowledge as needed, using appropriate learning strategies.
Program Educational Objectives: Three to five years after graduation, our graduates will be using the knowledge, skills, and abilities from their biological systems engineering degree to improve the human condition through successful careers in a wide variety of fields. They will be effective leaders, collaborators, and innovators who address environmental, social, technical, and business challenges. They will be engaged in life-long learning and professional development through self-study, continuing education, or graduate/professional school.
Well-qualified juniors and seniors in biological systems engineering who are interested in graduate study may apply for concurrent enrollment in the Graduate College to simultaneously pursue a Bachelor of Science degree in biological systems engineering and a Master of Science degree in agricultural engineering. Under concurrent enrollment, students are eligible for assistantships and simultaneously take undergraduate and graduate courses.
A concurrent Bachelor of Science and Master of Business Administration program is also offered by the department.
The department also offers a Bachelor of Science curriculum in agricultural engineering. See College of Engineering. Additionally, the department offers Bachelor of Science curricula in agricultural systems technology and in industrial technology. See College of Agriculture and Life Sciences.
The department also participates in interdepartmental majors in environmental science, sustainable agriculture, human computer interaction, and toxicology (see Index).

The Department of Agricultural and Biosystems Engineering has concurrent Bachelor of Science /Master of Science (B.S./M.S.) programs designed especially for departmental seniors who wish to pursue advanced studies. Concurrent B.S./M.S. programs are: agricultural engineering (BS) with agricultural and biosystems engineering (M.S.) and biological systems engineering (B.S.) with agricultural and biosystems engineering (M.S.).
The concurrent B.S./M.S. program allows seniors to:
- Become eligible for a research assistantship during their senior year.
- Complete an M.S. degree (with thesis) within 18 months of B.S. graduation.
For more information about our concurrent undergraduate and graduate programs in Agricultural & Biosystems Engineering, visit: https://www.abe.iastate.edu/graduate-students/abe-concurrent-degrees/.
Graduate Study
The department offers Master of Science, Master of Engineering, and Doctor of Philosophy degrees with a major in agricultural and biosystems engineering. Within the agricultural and biosystems engineering major the student may specialize in advanced machinery engineering, animal production systems engineering, biological and process engineering, occupational safety engineering, or water and environmental stewardship engineering. Details on current research programs available at http://www.abe.iastate.edu/.
For the Master of Science program, at least 30 credits of acceptable graduate work must be completed with a minimum of 22 credits of course work; corresponding numbers for the Master of Engineering program are 32 and 27. For the Doctor of Philosophy degree, at least 72 credits of acceptable graduate work must be completed with a minimum of 42 credits of course work. All Ph.D. students must complete a teaching/extension experience prior to graduation.
The department also offers both master of science and Doctor of Philosophy degrees in industrial and agricultural technology.
