Biology, B.A.

Biology is a dynamic science aimed at understanding living organisms and how they interact with the environment. Saint Louis University's biology program offers courses that emphasize concepts over facts and provide a foundation for careers in the life sciences, health professions, K-12 education and advanced post-graduate study in various disciplines. The Bachelor of Arts in Biology at SLU provides maximum flexibility in selecting upper-division courses and is favored by students seeking double majors. SLU also offers a Bachelor of Science in Biology. 

• SLU's biology program is enriched by interactions with the School of Medicine, Missouri Botanical Garden, Donald Danforth Plant Science Center, Saint Louis Zoo and a growing number of St. Louis-based life science companies. Research experiences and internships provide students with opportunities to study biology beyond the classroom.
• SLU's Department of Biology has a field station that provides unique opportunities for students to explore ecology, conservation and environmental science in an Ozark forest ecosystem. The field station offers students opportunities to take a summer class, conduct undergraduate research and participate in a semester-long program of field biology coursework.
• Biology students at SLU are encouraged to participate in co-curricular activities. Groups such as Beta Beta Beta, the biology honorary society, and Alpha Epsilon Delta, the preprofessional honor society, are social and academic organizations that further students’ interest in biology while exposing them to its relationship with other scientific disciplines.

Curriculum Overview

The undergraduate curriculum in the Department of Biology is diverse and meets a variety of interests in the rapidly expanding fields of the biological sciences. It is also designed to provide an intensive educational experience for students in other disciplines who are interested in biology. In addition to courses in Macelwane Hall, the department offers courses at the University’s Reis Biological Station, located by the Huzzah Creek in the Missouri Ozarks.

The Bachelor of Arts degree in biology provides flexibility in selecting upper-level courses and is favored by students interested in double majors.

Fieldwork and Research Opportunities

The benefits of SLU's biology program include several internship and career opportunities. Advanced undergraduate students with good academic records are encouraged to apply for teaching or learning assistant positions. In addition to a stipend, students gain teaching experience and the opportunity to help others become interested in biology.

Biology majors can enroll in courses that provide credit for structured internships through collaborations with various local organizations, including the Missouri Botanical Garden, Saint Louis Zoo, Sigma-Aldrich, Bayer and firms in the growing biotechnology field.

Careers

SLU's biology major develops strong critical thinking and problem-solving skills that provide excellent preparation for professional schools, such as:

• Medical school
• Veterinary science school
• Dental school
• Optometry school
• Graduate school in a broad range of disciplines

The skills biology majors gain also open the door to a wide variety of career options in health care, biotechnology, environmental management, conservation, education and the pharmaceutical industry.

Recent SLU biology majors have received grants from Sigma Xi and the National Science Foundation and prestigious fellowships from the National Science Foundation, Fulbright Scholar Program, Mayo Clinic, Smithsonian Institution, NeuroSURF and the American Society for Microbiology.

Scholarships and Financial Aid

There are two principal ways to help finance a Saint Louis University education:

• Scholarships: Scholarships are awarded based on academic achievement, service, leadership and financial need.
• Financial Aid: Financial aid is provided through grants and loans, some of which require repayment.

Saint Louis University makes every effort to keep our education affordable. In fiscal year 2025, 99.6% of first-time freshmen and 92% of all students received financial aid and students received more than $517 million in aid University-wide.

For priority consideration for merit-based scholarships, apply for admission by Dec. 1 and complete a Free Application for Federal Student Aid (FAFSA) by Feb. 1.

For more information on scholarships and financial aid, visit the Office of Student Financial Services.

1. Graduates will know core concepts of biology at all levels of biological organization. (Students will demonstrate their knowledge of the five core conceptual areas of biology identified by the Vision and Change report (AAAS, 2011): structure and function; information flow and storage; evolution; transformations of energy and matter; systems) at the cellular/molecular, organismal and ecosystem levels).
2. Graduates will apply knowledge of biology and scientific ways of thinking to reason about complex questions. (Students will apply their understanding of biology and scientific reasoning skills to work on questions that require applying fundamental paradigms and ways of thinking across diverse biological systems. Application problems may require, for example, that students construct models, provide explanations, analyze texts or figures, recognize patterns, make inferences and predictions. Application problems should range from course- and content-specific questions to broader social, environmental and ethical questions).
3. Graduates will use the tools of biology. (Students will acquire and practice biology laboratory and/or field techniques, manipulate and interpret data, and practice drawing conclusions from evidence).

Biology students must complete a minimum total of 48 credits for the major, 25 of which must be in BIOL subject code at the 3000 level or above.

Independent Research

A total of 3 credits of BIOL 3970 Independent Research in Biology (1-3 cr), BIOL 4970 Advanced Independent Research (1-4 cr), and/or BIOL 4980 Advanced Independent Study (1-3 cr) can be counted toward the B.A. degree. These courses do not count as structured lab courses.

Continuation Standards

Students must have a 2.00 grade point average (GPA) in all courses used to fulfill major requirements. Students who fall below the 2.0 GPA in major coursework will be placed on program probation. If a student's major GPA falls below a 2.00 for two consecutive semesters, the student will be eligible for dismissal from the major.

This roadmap is just one example of a semester-by-semester plan of study for this program. There are other plans students can and do take. The plan of study for each particular student is established in consultation with each student’s academic advisor; this roadmap does not replace academic advising appointments.

Roadmap notes:

• This Roadmap assumes full-time enrollment unless otherwise noted.
• Courses/Milestones marked with an “!” are critical and must be completed in the semester listed in the Roadmap to ensure a timely graduation.
• Course availability and sequencing are subject to change.

Note: SLU-Madrid and SLU-St. Louis program requirements vary slightly by campus.

Biology is a fast-growing field of science. Important social issues such as developing cures for widespread diseases like cancer, fuel alternatives, managing natural resources, genetically modified food sources, or climate change can only be addressed by professionals who are well-educated in biology. Biology is a dynamic science aimed at understanding living organisms and how they interact with the environment.

Saint Louis University-Madrid's biology program offers courses that emphasize concepts over facts and aim to provide a foundation for careers in the life sciences, health professions, education and advanced post-graduate study in various disciplines.
