What is a Biologist?
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.
Degree Specializations
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.
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).
Because of our size, we are able to offer individualized attention in our classes and labs. Professors take a personal interest in their students and assist them in securing internships with other universities or companies in various industries. These relationships are critical for students wanting to apply to graduate or medical schools.
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.

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
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
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)
- Water quality monitoring in a local stream (environmental biology)
- Seasonal changes in mayfly abundance at Lake McQueeney (environmental biology)
- Evolutionary changes in soil bacteria (microbiology)
- Creation of a porcine model for diabetes (physiology)
- Epidemiology and characterization of methicillin-resistant Staphylococcus aureus (microbiology)
Some majors do research in the TLU chemistry department during the summer and are often double-majoring in biology and chemistry.
Off-Campus Summer Research
- Programmed cell death in dinoflagellates (marine biology/cell biology)
- Effects of nanoparticles on bacteria of Galveston Bay (marine biology/molecular biology)
- Effects of hyperosmolarity on Vibrio bacteria (marine biology/cell biology)
- Effects of maternal nutrient restriction on mammalian development (physiology)
- Biochemical properties and hemostatic function of plasma-derived vs. recombinant fibrinogen (molecular biology/physiology)
- Maternal and fetal insulin-like growth factors (physiology/molecular biology)
- Role of sensory nerves in the vasoconstrictor response to local cooling in humans (physiology)
- Investigation of a genetic bottleneck in the California treefrog (genetics/environmental biology)
- Mercury in marine fish in the Gulf of Mexico (environmental biology/chemistry)
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.

Pre-Professional Health Programs
TLU and University of Incarnate Word (UIW) in San Antonio have memorandums of understanding (MOU) as part of UIW's Health Professions Pathway.
Students interested in pre-professional health programs often major in Biology, Biochemistry, or Chemistry, although pre-professional students can come from any major. TLU offers pre-professional programs in the following professions:
- Dentistry
- Medicine
- Nursing
- Occupational Therapy
- Optometry
- Pharmacy
- Physician Assistant
- Physical Therapy
- Veterinary Science
Students interested in pursuing careers in these programs work with members of TLU's Health Professions Committee for individualized advising.
