Biologists look at life from the molecular level, discover how organs and systems work together, and carry these ideas to the level of species, ecosystems, and evolution. Some biologists specialize in a subdiscipline like cell biology, zoology, animal physiology, or ecology. Others use their knowledge and skills more generally in medicine or biotechnology. All of them are concerned with how life functions and how to ensure that we can continue to function in the best way possible. The study of biology gives students the background and practical skills in math, chemistry, and physics that’s needed to understand contemporary biology. Students choose from a wide range of course options like cell biology, ecology, plant biology, invertebrate zoology, and genetics so that they can begin to specialize in fields like microbiology, molecular biology, or plant biology. The biology major prepares students for careers in a variety of life science fields, including medicine, dentistry, veterinary, and other health-related fields. Biologists also work in fisheries, forestry services, county and state agencies, museums, aquariums, research vessels, and marine stations.
