Biological Sciences Major | LSU

Biological Sciences

You are intrigued by the mechanics of life, how molecules are formed, and the structure of cellular organisms.

About Biological Sciences Careers 

With a field that’s as broad as life itself, the biological sciences major gives you ample exposure to help you figure out where you belong within this area of study. Upon graduation you will be well prepared for placement in graduate school; medical, dental, optometry, pharmacy, or veterinary school; and in careers that range from public health to environmental science.

Concentrations Available:

  • Marine Biology: In marine biology, you will study, protect, and manage the organisms, plants, and animals that live in oceans or saltwater environments. And since two-thirds of the Earth’s surface is covered with water, you’ll have plenty of research material.
  • Secondary Education: This concentration allows you to pursue an undergraduate degree in biological sciences and earn a secondary teaching certificate at the same time though the LSU GeauxTeach Math & Science program.
