Program Overview

The Bachelor of Science in Biology program at Texas A&M University-Central Texas provides quality education with a rigorous, in-depth introduction to the breadth of the biological sciences discipline. Our professional faculty guide students through a high-quality course of study that will prepare you for future success. Through core courses and a diverse selection of upper-level courses, our program will prepare you for an entry-level career in biology or admission into a graduate school or professional health program (medical, veterinary, pharmacy, physical therapy or dental). This flexible degree program provides a broad knowledge base of the biological sub-disciplines, allowing you to specialize in biotechnology, ecology and conservation biology, and organismal biology. Pre-health students can specialize in either biotechnology or organismal biology, depending on their specific interest.

Laboratory Experience

Our exceptional faculty and state-of-the-art and natural laboratories and offer students the essential knowledge, skills, and experience needed for a successful and rewarding career in science.

State-of-the-art laboratories:

Our students benefit from learning in our five teaching and two research laboratories equipped with high-quality instrumentation. We give our undergraduate students the essential workforce experience that many students only get in graduate programs. Our Instrumental and Analytical Chemistry laboratories allow students to learn to use High Performance Liquid Chromatography, Gas Chromatography, Gas Chromatograph/Mass Spectrometer, AKTA PrimePlus System, UV-Vis Spectrometry, Fluorescence Spectrometry, Atomic absorption spectrometry, Electrochemical analyzer, Rotavapor, and a Thermal Gravimetric analyzer.

Additionally, our Cell, Proteomics, Biochemistry and Molecular biology laboratories use quantitative real time PCR, SDS PAGE gel electrophoresis, western blot, gel filtration chromatography, protein purification, protein crystallography, immunosorbent assay, and Chemidoc imaging, among others.

Natural laboratories:

For students that want to experience an outdoor laboratory, our campus sits on more than 600 acres of undeveloped land. Students learn to assess environmental factors such as soil composition, water quality, arthropod diversity, and plant diversity in our Ecology, Botany, Entomology, Invertebrate Zoology laboratory courses.

Killeen teen sets her eyes on a Master's degree in organismal biology

Most of us don't start thinking about what we want to study in college until our junior year of high school. One Killeen teenager is already enrolled in a Master's program, with two associate's degrees and one Bachelor's, all concentrated in the STEM field.

Customize Your Degree

At A&M-Central Texas, students can tailor their degree plan to their personalized interest and career goals. Areas of study include:

Biotechnology Concentration

Biotechnology Concentration
The Biotechnology Concentration is for students who are interested in biology on a molecular or chemical level in such areas as biochemistry, cellular and molecular biology including students interested in pre-health (i.e. careers in medicine, dentistry, veterinary, physical therapy, etc).

Ecology and Conservation Biology Concentration

Ecology and Conservation Biology Concentration
The Ecology and Conservation Biology Concentration is for students who have an interest in studying the roles and interdependence that organisms have within an ecological system as well as conserving the ecosystem.

Organismal Biology Concentration

Organismal Biology Concentration
The Organismal Biology Concentration is for students who have an interest in biology on the organismal/individual level including students interested in pre-health (i.e. careers in medicine, dentistry, veterinary, physical therapy, etc.).

Golden Cheeked Warbler Refuge Habitat

The Golden Cheeked Warbler has been on the endangered list since 1990. It is only found nesting in the Oak-Juniper woodlands of Central Texas. Our campus has set aside several of its almost 600 acres of land as a refuge habitat for the conservation of this endangered bird. These areas will not be developed as the university grows to maintain essential nesting sites.

"Not only does the program allow you to gain critical thinking and excellent communication skills, but the professors further instilled confidence and strengthened a love of science in me... You can tell the faculty truly care about the students because they actually take the time to invest in your success and accomplishments...Although the program is very rigorous and made me learn in a way I have never been pushed before, I am eternally grateful to the department and professors for everything they have done for me and I feel confident in the skills I have developed as an undergraduate student in the Biology Department."

Martha's Monarchs Butterfly Refuge

The Conservation Biology students designed a refuge habitat for the Monarch butterfly whose population decline in past years is of great concern to ecologists. The construction of this area was put on hold due to the COVID-19 pandemic but, when finished, it will provide migrating Monarchs with needed egg laying and nectar plants in an effort to conserve this species and provide an area for essential research on the causes of population decline. It will also be designated as an official Monarch Waystation through Monarch Watch. In honor of Martha Gail Minor Sherrill, we have named it "Martha's Monarchs Butterfly Refuge".
