Biological Sciences

Begin your studies in biology

Biology plays a key role in scientific advancements that improve our way of life. Biologists assist with medical research by helping develop new medicines and treatments used to prevent, treat or cure diseases such as cancer or Alzheimer's. In agriculture, biological research contributes to the development of genetically engineered crops that provide greater yields and require less pesticide and fertilizer.

Biologists also lead efforts to discover new and improved ways to clean and preserve the environment as well as alternative sources of energy, such as biofuels and biomass.

Entry level jobs in biology include: biological technician, conservation biologist, environmental biologist, microbiologist, zoologist/wildlife biologist, pharmaceutical sales representative or secondary education teacher.

Graduate degrees can lead to careers such as biochemist, biophysicist, medical doctor/scientist, epidemiologist, physical therapist and pharmacist.
