Program Details

Explore your interest in biodiversity and the natural world and gain the flexibility to pursue a career in medicine, health, agriculture or environment. The Bachelor of Science in Biology is offered by a top-ranked program renowned for groundbreaking scientific discoveries and a long tradition of involving students in leading-edge research.

The curriculum provides a broad overview of the structure, function and evolution of biological systems from component parts, to organisms, communities and ecosystems. As a biology major, you will choose one of two degree emphases: Biomedical Sciences or Organismal Biology.

As a graduate, you may choose to pursue a career in a wide range of fields including medical and clinical research, healthcare, forensic science, conservation or wildlife biology. Biologists often seek to address grand challenges in medicine, agriculture and environment. This includes viral evolution and global pandemics, quantitative genetics and advanced plant and animal breeding, and biodiversity conservation and global change.

Our graduates are highly successful in gaining admission to graduate and professional programs that lead to careers in medicine, pharmacy, optometry, dentistry, veterinary medicine, law, public health and education.

The online BS in Biology can be completed fully online. However, some post-graduate professional programs do not accept prerequisite courses taken online. Be sure to check the policies for post-graduate programs you may want to attend.

Eligibility: Students must meet general university admission requirements: First Year, Transfer, International and Readmission.

*Residents of some U.S. Territories may not be eligible. Please see our Eligibility & State Authorization page for more information.
