Biology, BA, BS


Through observation and experiments, biologists gain an understanding of the nature and functions of the living world, integrating this knowledge with the aid of chemistry, physics and mathematics. Students at the University of Dallas explore biology through an active learning process that incorporates hands-on experience in the laboratory and field.

Every organism on the planet is interconnected.

Biology is the exploration of the entire world of the living and the material universe as it relates to living processes. Through the study of biology, students gain an understanding of the nature and behavior of the living world and integrate this knowledge with the aid of chemistry, physics and mathematics. Scientific truths and concepts are presented in such a way as to challenge students to take an active part in the learning process through hands-on laboratory and field experiences.

The Biology curriculum is divided into three levels to ensure exploration of the full breadth of the biological sciences. In the Molecules to Cells level, students explore cellular and subcellular processes through examination of microbiology, molecular biology, genetics and cell physiology. The second level, Cells to Organisms, examines the arrangement of cells into higher-order organization in the organism through the study of anatomy, physiology, plant biology and developmental biology. At the Organisms to Populations level, the interaction between organisms and their environment is expanded to include ecological, behavioral and evolutionary processes. Students majoring in biology complete upper-division course work at each of these levels, while also having the opportunity to spend additional course work going into greater depth within a level.

The Biology Department curriculum is designed to prepare students for graduate work at the master’s or Ph.D. level, for teaching in junior high and high school and for pursuing laboratory or field-based research careers. The curriculum includes course work necessary for satisfying entrance requirements to schools in health related fields such as medicine, dentistry, veterinary science and physical therapy.

A program leading to the Bachelor of Science in Biochemistry is offered jointly between the Departments of Biology and Chemistry.
