Biological systems engineering (BSE) is the application of engineering principles to biological and agricultural systems which greatly impact our food, fiber, and renewable energy resources. Since biological systems engineering programs focus heavily on the protection and conservation of natural resources, it is not uncommon for them to be described as sustainable engineering programs.

Within the BSE program a student must enroll in either the General Program area or in one of the following three specialization areas: Machinery Systems Engineering, Natural Resources and Environmental Engineering, or Food and Bioprocess Engineering. The specialization in Food and Bioprocess Engineering is split into a Food Engineering track and a Bioprocess Engineering track.

Students who complete all degree requirements are awarded a Bachelor of Science–Biological Systems Engineering degree. A student who completes one of the three program specializations will have the area of specialization identified on the official transcript. The BSE program, like all undergraduate engineering programs on the UW–Madison campus, is accredited by ABET. Accreditation by ABET is an indication of program quality and has major benefits for individuals seeking registration as a licensed professional engineer. A UW–Madison BSE graduate may apply for licensure as a registered professional engineer once they have passed the Fundamentals of Engineering (FE) exam, obtained four years of qualifying engineering work experience, and have passed the Professional Engineering (PE) exam. To obtain a BSE degree from UW–Madison, a student must have taken (but is not required to have passed) the FE exam as part of their Senior Design sequence. Information about the FE exam can be found at Fundamentals of Engineering Exam.

Graduates work in career fields associated with the growth, harvest, transportation, processing and storage of food, feedstuffs, biomass for energy production and forestry products. This includes, but is not limited to, jobs involving the design, construction and management of: bio-energy production facilities, greenhouses, food processing plants, soil management systems and erosion control structures, irrigation and drainage systems, wastewater and solid waste treatment/recycling operations, animal housing facilities, aquaculture enterprises, systems for improved air quality, and equipment for agricultural production, material handling, processing, and packaging. Job opportunities for BSE graduates remain plentiful and show no signs of decreasing given (1) the increase in world population and corresponding increasing need for food, fiber and renewable energy, (2) the measurable shortage of highly trained technical personnel in the United States, and (3) the constantly expanding emphasis on protection and conservation of natural resources.

The UW–Madison BSE program is traditionally known for its emphasis on undergraduate education which is reflected in outstanding one-on-one advising and smaller class sizes.

The BSE program requires completion of a minimum of 125 credits to be eligible for graduation. Note that this is higher than the minimum for other CALS programs.

Entry to this professional program requires students to meet the five admission requirements detailed below. Students are admitted to the department as pre-Biological Systems Engineering until they meet the admission criteria. Admission eligibility must be confirmed by the department.

  1. Must complete a minimum of 24 degree credits.
  2. Must have completed a minimum of 17 graded credits of calculus, statistics, chemistry, computer science, statics, biology, and physics courses required for a BSE degree.
  3. Must have a math and science grade point average (M&SGPA) of at least 2.65 with a minimum grade of C in every course used to calculate the M&SGPA. The M&SGPA is based on: math courses numbered 217 and above (MATH 228 is excluded); statistics courses numbered 224 and above; all chemistry courses; all biology courses (courses with biological science breadth; maximum three courses, any required course must be included if taken); computer sciences courses numbered 302 and above (COMP SCI 402 is excluded); E M A 201 Statics; and physics courses numbered 201 and above. For any course that a student repeats, only the most recent grade will be used in the calculation. Any transfer course from another university that is included in the previous list must be included in the GPA calculation. 
  4. Must be in good academic standing—i.e., not on academic probation or dropped status.
  5. Must successfully complete introductory chemistry (CHEM 103 General Chemistry I & CHEM 104 General Chemistry II, or CHEM 109 Advanced General Chemistry, or equivalent) and math through MATH 222 Calculus and Analytic Geometry 2.

Revisions to #3 effective for students joining the department in 2019: Grades in courses Math 228 and Computer Science 402 are excluded from calculation.  A maximum of three courses with biological science breadth may be used. If BSE 349 has been completed, it must be included in the calculation.

University General Education Requirements

All undergraduate students at the University of Wisconsin–Madison are required to fulfill a minimum set of common university general education requirements to ensure that every graduate acquires the essential core of an undergraduate education. This core establishes a foundation for living a productive life, being a citizen of the world, appreciating aesthetic values, and engaging in lifelong learning in a continually changing world. Various schools and colleges will have requirements in addition to the requirements listed below. Consult your advisor for assistance, as needed. For additional information, see the university Undergraduate General Education Requirements section of the Guide.

All students are assigned an advisor when they join the department. Freshmen and other pre-biological systems engineering students work with a professional staff advisor. Once full admission requirements are met, students transition to a faculty advisor in their specialization area. All students are encouraged to outline a degree plan soon after declaring the major. Curriculum checklists for each track have been developed to assist students in this process. Many BSE courses are offered only once each year, which must be considered as part of the planning process. Student plans may vary based on previous coursework, plans for study abroad or certificate interest, co-op semesters, and individual interests. Prospective students should contact the department at or 608-262-3310 for more information. 


Solve. Create. Invent. Sustain.

Biological Systems engineers combine their knowledge of life sciences, agriculture, and technology, with engineering problem-solving skills to address many of the most pressing problems facing the world today: providing safe and nutritious food, generating renewable energy, and preserving the natural environment.

If you like hands-on problem solving, you should consider Biological Systems Engineering (BSE) as your major.

Graduates can expect to find biological and agricultural engineering careers in a wide range of agencies and industries solving problems in many different areas. Graduates work in career fields associated with the growth, harvest, transportation, processing and storage of food, feedstuffs, biomass for energy production and forestry products. This includes, but is not limited to, jobs:

  • designing and managing bio-energy systems, greenhouses, and food processing plants
  • designing animal housing and environmental control systems
  • developing irrigation and drainage systems
  • protecting soils, and air and water quality
  • designing and running wastewater treatment and waste management operations
  • designing off-road equipment for agricultural production and material handling.

Job opportunities for BSE graduates remain plentiful and show no signs of decreasing given (1) the increase in world population and corresponding increasing need for food, fiber and renewable energy, (2) the measurable shortage of highly trained technical personnel in the United States, and (3) the constantly expanding emphasis on protection and conservation of natural resources.

Through our curriculum, BSE students have opportunities for many high-impact learning experiences including hands-on lab courses, involvement in student organizations, and BSE’s capstone design classes. Introductory engineering courses and career management courses are built into the curriculum to make sure you have a community to succeed both at UW–Madison and after you graduate.

Beyond traditional classes, our students work or perform independent study with professors not only in BSE but throughout the campus. Many campus labs and shops need students who know how to design and build systems, skills at which you will excel through your experiences in BSE. Outside the university, BSE students can take advantage of internships and co-ops, but are also in high demand for programs such as Peace Corps and Engineers without Borders. BSE has an active student organization ASABE, where students network with professionals and provide service projects to the community.

As a BSE student, you will be proud that you are contributing to the social and economic well-being of Wisconsin and beyond by designing solutions to feed and fuel the world in a sustainable manner. Many of our students go on to work in the following areas:

  • Machinery systems that support the agricultural production sector including precision agriculture, cultural and processing technology, and logistics for crop and animal production with a focus on dairy facilities and milking technology.
  • Natural resource systems that support both agricultural producers and environmental agencies in the areas of air and water quality, and waste mitigation and utilization.
  • Food production systems that support the food industry striving for improvements in food processing, safety, and security.
  • Bioprocessing systems that support bioenergy and bioproducts industries including biomass production and logistics systems, biomass conversion technologies, and forest products.

Or, you may take the skills you learn through your experiences at BSE and apply them to a brand new challenge. We are excited to see what you will do.


All BSE students are encouraged to apply annually for department and CALS scholarships through the Wisconsin Scholarship Hub (WiSH). Each year the BSE department selects more than two dozen outstanding students to receive financial support through scholarships. 


The Biological Systems Engineering Shop is dedicated to providing BSE students a hands-on experience with machining equipment found throughout the production sector of industry. The shop, located at 540 Elm Drive, is open to all BSE students who have completed the shop safety form (renewed annually) and have read and understood the Shop Rules and Regulations. In addition, a yearly refresher is required which consists of watching the shop safety presentation and completing a short, yearly safety quiz. Whether you have never worked in a shop before, or already feel at home working with this type of machinery, we welcome you to the BSE Shop and want to make you feel comfortable in this learning environment.

BSE students are welcome to learn various machining and metal fabrication techniques as well as woodworking skills. These skills are aimed at improving students’ understanding of the design, fabrication, and assembly processes through one-on-one training and hands-on operation of the machines—before they enter the workforce. To operate any of the shop machines, students must first be authorized by completing the online Canvas course and provide a one-on-one, hands-on operation with the shop supervisor to demonstrate understanding of the machine’s controls and capabilities. To maintain a safe work environment, the shop is under 24-hour video surveillance. For additional details, please see Shop Info for Students

CAE Computer Lab

A dedicated student computer lab in room 217 of the Agricultural Engineering Building offers 10 computer workstations and space for group work. These machines have the same software packages as those found in Computer Aided Engineering labs on the Engineering campus. A CAE printer is also provided.

The B1 Lounge

In the basement of the Agricultural Engineering Building is a large room with multiple tables and chairs that can be used for group study or individual work. Department-wide social events are also held here. A microwave oven and vending machines are available for student use.
