Biology Degree Program
Bachelor of Science (BS) and Bachelor of Arts (BA) in Biology
The field of biology is vast. From ecology and genetics to anatomy and neuroscience, biology majors are interested in studying life to discover its variety and characteristics.
This curiosity and desire for learning by doing is embraced by professors who mentor their students and engage them in challenging research and professional development opportunities outside the classroom.
Why Biology at TLU?
Our faculty are committed to excellence in teaching, and at TLU, you’re likely to work with many of the same professors through your college years. This continuity fosters relationships and allows for one-on-one interactions, academic mentorship, and guided learning to help students reach their full potential.
Course Experiences
All TLU Biology degrees now include a semester of research, because we believe that to be trained in science means that you need to be exposed to the "doing" of science in the form of scientific research. Biology students are encouraged to take advantage of faculty-mentored undergraduate research opportunities. Every senior participates in a capstone project that may include an original research project, a poster presentation and an oral presentation that is presented at our Student Academic Symposium in the spring.
Courses students might take include: Biodiversity, Biological Systems, Anatomy & Physiology, Genetics, Microbiology, Neuroscience, Biochemistry, Molecular Biology, Immunology, Cell Biology, Evolutionary Biology, Plant Biology, and Aquatic Biology.
Majors also take courses in chemistry, math, and physics to better understand the full scope of biology and how these areas work together.
From ecology and genetics to physiology and neuroscience, biology majors are actively engaged in medical, environmental, and other sciences vital to our ever-changing world.
Research Experiences for Every Student
As a TLU biology student, research will play a key role in your success. Research opportunities are offered throughout the school year and during our unique eight-week paid summer research program. With full support from faculty, you’ll have the chance to follow your curiosity and conduct research in areas like DNA barcoding, plant and wildlife diversity, and stem cell research.
Degree Plans
Degree Specializations
General Biology: This specialization covers the widest scope of biology, with courses from across the discipline. All biology degrees prepare students for graduate and professional schools, work in laboratories and other scientific endeavors, and teaching (with appropriate certification).
Molecular Biology: This specialization is all about the study of molecules such as DNA, RNA and proteins. Students interested in the health professions often get degrees in this specialization and this includes, but is not limited to, pre-medicine, pre-veterinary, pre-dental, pre-physician assistant, genetic counseling, and other health specialties.
Environmental Biology: This specialization focuses on organisms and their relationships to each other and their environments. Students pursuing careers in ecology, environmental biology, botany, zoology, natural resource management, etc. would take this track.

Internship & Research Opportunities
The biology faculty believe that completing an internship or research experience helps students to learn more about biology, develop professional skills and an understanding of biology-related careers, while enhancing their applications for jobs and graduate and professional schools. The faculty maintain a network of contacts in various medical schools, graduate schools, and hospitals that enable us to find appropriate internships for our students.
Motivated students will have the opportunity to participate in a variety of internships or research fields to help establish their professional career. We work individually with the students to ensure their success.
TLU Biology Majors Have Had Internships At:
- Guadalupe Regional Medical Center
- UT School of Public Health
- Various medical and dental clinics
- Veterinary clinics
- San Antonio Zoo
- Texas Parks and Wildlife
- San Antonio Medical Center
- UT Health Science Center - San Antonio
- Texas A&M University - Graduate School - Department of Bioengineering
- Joint Admission Medical Program
- Public high schools (biology education)

Careers in Biology
Our graduates pursue careers in ecology, environmental biology, botany, zoology, and natural resource management. They pursue graduate studies in medicine, veterinary science, dentistry, and other health specialties. They work in laboratories and teach. There are so many potential paths to take—and we’re here to help you get where you want to go
All biology majors develop a broad knowledge of biology and take supporting courses in chemistry, physics, and statistics. All students develop skills in:
- using the scientific method,
- using laboratory techniques,
- reviewing scientific papers,
- presenting scientific information both orally and in writing,
- effectively analyzing and presenting numerical information in graphs
Students in the molecular biology track develop advanced skills in laboratory techniques, while students in the environmental biology track develop advanced skills in field techniques and identification of animals and plants.

Weston Ranch
The Weston Ranch is home to diverse plant and animal life, offering acres and acres of possibility—allowing our students a place to explore and study the creeks, prairie, and woods. TLU biology professors and students have been conducting summer research at the ranch, located in nearby Marion, since 2007
Students can be hired for the summer as paid biodiversity researchers through our grant-funded program at this large ranch only 15 minutes from Seguin. Students document the flora and fauna of the ranch and can develop independent projects to present at scientific meetings. Students can continue their research during the academic year as paid research assistants.
-
Research & Seminars
Students can participate in research projects with faculty members either during the semester or during the summer. Recent projects include:
- Stress-response pathways in bacteria (microbiology/molecular biology)
- Aquatic macroinvertebrates of a spring-fed spring (environmental biology/zoology)
- Isolation of ethanol-producing bacteria for producing biofuels (cell/molecular/microbiology)
- Vascular plants and lichen survey of a local ranch (environmental biology/botany)
- Effects of spinal decompression therapy (biomedical)
- Distribution and abundance of rare mayfly in a nearby lake (environmental biology/zoology)
- Analysis of data from a local school district on relationships between physical fitness and academic achievement (public health)

Seminars
Biology Seminars provide students and faculty an opportunity to learn about the latest research in biology, as well as an opportunity to present their own research and ideas. All biology seniors present a 15-minute seminar in their last year at TLU.
Seminars are usually held at 1 pm on Fridays in Moody Science 101.
