The Bachelor of Science in Biology is offered by our top-ranked program renowned for groundbreaking scientific discoveries and a long tradition of involving students in leading-edge research. This degree is for students interested in biodiversity and the natural world who want the flexibility to pursue careers in medicine, health, agriculture and environment. The curriculum provides a broad overview of the structure, function, and evolution of biological systems from component parts—molecules and cells—to organisms, communities and ecosystems. Biology majors choose from two degree emphases: Biomedical Sciences and Organismal Biology.

Biomedical Sciences

The Biomedical Sciences emphasis is for students who plan to pursue careers in biomedical research, pre-med students interested in medicine and other health professions. The program of study provides training in systems biology with a focus on anatomy, physiology and biochemistry, and includes all of the coursework covered on the MCAT and required for admission to medical school.

Featured Courses

ECOL 220 – Evolutionary Medicine

Like all biological systems, both disease-causing organisms and their victims evolve. Learn how the basic processes of evolution can help us understand the genetic roots of human diseases.

ECOL 326 – Genomics

This course introduces both historical and cutting-edge methods for investigating genomes, and integrates exercises that apply web-based computational tools for genome analysis.

ECOL 379 – Evidence-based Medicine

The history and applications of the randomized clinical trial are explored in-depth, as are associated statistical methods and concepts. Students design their own trials, and at least one of the trials is carried out by the entire class during the semester.

ECOL 437 – Vertebrate Physiology

A study of the physiological mechanisms of vertebrates. Topics include reproductive systems; digestion; terrestrial osmoregulation; endocrine and nervous systems; energetics; and the thermodynamics of dinosaurs.

Organismal Biology

The Organismal Biology emphasis is for students interested in careers as professional biologists and educators. The program of study provides training in systems biology with a focus on animal behavior, genetics, ecology and evolution.

Featured Courses

ECOL 206 – Environmental Biology

Learn about the natural forces that generate and maintain the diversity of life on Earth, as well as the myriad interactions among biotic and abiotic components of ecosystems. Assess the role that humans have played in changing the natural environment.

ECOL 360 – Marine Ecology & Conservation

Examine major conservation challenges faced by the marine environment, and use principles of ecology and evolution to propose solutions to those challenges.

ECOL 409 – Evolution of Infectious Disease

Pathogens yield key insights into the nature of the evolutionary processes that shape all of life on Earth. Learn how evolutionary insights and approaches advance our understanding of the nature of diseases, help us track their origins, and enable us to control their spread.

ECOL 487R – Animal Behavior

Examine the diversity of animal behavior among species. Gain the ability to find, evaluate, synthesize, and apply scientific information.
