Biology Major


Biology is the science of life in all its forms, from the simplicity of a one-celled organism to the complexity of the human body.

Like all living things, the field of biology is dynamic, constantly growing, rapidly changing and replete with new discoveries and advances.

At Illinois Wesleyan, the Biology Department provides students with a superior undergraduate education across a variety of biological fields. Students can then parlay that education into a variety of career opportunities, including medicine, research, education and law.
