Description

Website: http://bsen.unl.edu/

Biological systems engineering (BSEN) is one of two engineering degree programs offered in the Department of Biological Systems Engineering. BSEN students emphasize engineering course work in one of three areas; biomedical engineering, bioenergy and food engineering, or environmental and water resources engineering. A biological systems engineer could work on systems to micropropagate tissue culture, develop biomaterials and biofibers, design equipment and processes for producing foods and biofuels, or design devices for performing minimally invasive surgery. Still another could be responsible for developing biological sensors and imaging devices for detecting diseases in humans, for measuring plant and animal stress, or for controlling the environment of greenhouses and animal facilities. Biological systems engineers could also be involved in resolving environmental issues associated with waste management, water quality and sustainable energy production. Job opportunities for graduates are available in industry, public agencies, consulting, and private practice. A significant number of graduates pursue graduate school or studies in medical or law school.

By two to six years after graduation, BSEN alumni will share the attribute of improving the organization for which they work, and the community and country in which they live. They will do this whether they are involved in biomedical engineering, environmental or water resources engineering, bioenergy and food engineering, or other professional endeavors such as business, law or medicine. In doing so, they will:
 

  • provide innovative and effective solutions to problems in a variety of work environments through the use of their unique background in biological systems engineering and the biological sciences;
  • look beyond components in isolation thereby providing holistic solutions to complex issues involving (for example) interactions at the ecosystem, organism, organ, cellular or subcellular level;
  • think logically using appropriate elements of mathematics, science, and engineering to develop, manage, and interpret data, to correctly interpret new research findings, and to design new systems for the benefit of society;
  • successfully integrate technical knowledge with organizational, listening, communication, and interpersonal skills to lead and work effectively in teams, and to respectfully articulate the role of engineering decisions in the workplace, community, and world;
  • responsibly address issues such as health and safety, personal and professional ethics, cultural diversity, as well as the social, environmental, and global impacts of their work; and
  • continue their personal growth, professional development, and professional and community service through various opportunities provided by institutions, professional organizations and other venues.

The Department of Biological Systems Engineering is located in Chase Hall on East Campus. BSEN students participate in classes and laboratories on both the East and City Campuses. BSEN courses are offered on the East Campus. Basic courses in math, chemistry, physics, engineering sciences, computers, and electives in mechanical, civil, electrical, and chemical engineering are taken on the City Campus. Convenient bus transportation is available between campuses.

Students benefit from small classes and personal acquaintances with faculty. In consultation with their advisor, students select electives that permit specialization in an emphasis area applicable to their career aspirations. Many students work part-time on departmental research projects, gaining valuable experience for employment in industry and for graduate or professional studies. Students also benefit from summer jobs, internships and co-op programs. These opportunities give students practical experience to learn about careers in engineering. Students also gain valuable experience through participation in professional organizations such as the American Society of Agricultural and Biological Engineers, the Water and Environmental Federation, the Soil and Water Resources Club, the Biomedical Engineering Society, the Nebraska Society of Professional Engineers and the Society for Women Engineers.

Major Department Admission

Pre-professionally admitted COE students majoring in biological systems engineering (BSEN) have their records examined for advancement to professionally admitted status during the fall, spring, and summer immediately following the term in which 43 or more credits applicable to the BSEN degree have been completed. Students must be professionally admitted in order to enroll in AGEN 470/BSEN 470 Design I in Agricultural and Biological Systems Engineering.

To be professionally admitted to BSEN, the student must first meet the general Professional Admission criteria of the College of Engineering (i.e., completion of at least one semester in the College, a cumulative GPA of 2.5 or greater, and not having been already declined admission by two other engineering majors). BSEN Professional Admission criteria require consistent grades of C or better in calculus, calculus-based physics, chemistry, communications, and engineering science courses. Specifically, the student must have completed MECH 223 Engineering Statics and AGEN 225/BSEN 225 Engineering Properties of Biological Materials or BSEN 244 Thermodynamics of Living Systems with grades of a C or better to gain Professional Admission to BSEN. In addition, the student must complete the AGEN/BSEN Writing Assessment Exam (i.e., Grammar Slammer) before Professional Admission is granted.

Students who meet the above criteria with a cumulative GPA of 3.0 or greater with all grades above a C in UNL mathematics, science, engineering, and communications courses, and scoring 70 percent or higher on the AGEN/BSEN Writing Assessment Exam may be professionally admitted without further review by Department faculty. Students scoring less than 70 percent on the AGEN/BSEN Writing Assessment Exam must agree to a writing improvement plan with their academic advisor in order to be granted Professional Admission. Students not meeting the 3.0 GPA standard, or having grades below a C in the listed areas, will have their record reviewed by Department faculty for evidence of ability to succeed in BSEN. Under special circumstances, the Department may elect to defer Professional Admission for an additional term.

The Department faculty may recommend provisional admission and specify deficiencies and performance criteria to transition out of provisional status. If a student has not met the admission criteria and has not, in the opinion of the Department faculty demonstrated a minimum standard of good professional judgment in the pursuit of their academic program as expected of degreed engineers, they may be denied Professional Admission to the degree program. The student may appeal this decision to the BSE Department Head and then, if necessary, to the College of Engineering Curriculum and Academic Standards Committee.
 

College Requirements

College Admission

College Entrance Requirements

Students must have high school credit for (one unit is equal to one high school year):

  1. 4 units of mathematics: 2 of algebra, 1 of geometry, 1 of precalculus and trigonometry.
  2. 4 units of English.
  3. 3 units of natural science that must include 1 unit of physics and 1 unit of chemistry (chemistry requirement waived for students in construction management).
  4. 2 units of a single foreign language.
  5. 3 units of social studies.
  6. Students having a composite ACT score of 28 or greater (or equivalent SAT score) will be admitted to the College of Engineering even if they lack any one of the following: trigonometry, chemistry, or physics.
  7. Students having an ACT score of 19 or less in English (or equivalent SAT score) must take ENGL 150 Writing and Inquiry or ENGL 151 Writing and Argument.

A total of 16 units is required for admission.

Students must have an ACT (enhanced) score of 24 or greater (or equivalent SAT). Students who lack entrance requirements may be admitted based on ACT scores, high school rank and credits, or may be admitted to pre-engineering status in the Exploratory and Pre-Professional Advising Center. Pre-engineering students are advised within the College of Engineering.

Students for whom English is not their language of nurture must meet the minimum English proficiency requirements of the University.

Students who lack entrance units may complete precollege training by Independent Study through the UNL Office of On-line and Distance Education, in summer courses, or as a part of their first or second semester course loads while in the Exploratory and Pre-Professional Advising Center or other Colleges at UNL.

Students should consult their advisor, their department chair, or Engineering Student Services if they have questions on current policies.

Other Admission Requirements

Students who transfer to the University of Nebraska–Lincoln from other accredited colleges or universities and wish to be admitted to the College of Engineering (COE) must meet COE freshman entrance requirements and have a minimum cumulative GPA of 2.5 for Nebraska residents or 3.0 for non-residents. Students not meeting either of these requirements must enroll in the Explore Center or another UNL college until they meet COE admission requirements.

The COE accepts courses for transfer for which a C or better grade was received. Although UNL accepts D grades from the University of Nebraska at Kearney and at Omaha, not all majors in the COE accept such low grades. Students must conform to the requirements of their intended major and, in any case, are strongly encouraged to repeat courses with a grade of C- or less.

All transfer students must adopt the curricular requirements of the undergraduate catalog current at the time of transfer to the COE—not that in use when they entered UNL. Upon admission to UNL, students wishing to pursue degree programs in the COE will be classified and subject to the policies defined in the subsequent section.
