Biology

The B.S. in biology is a 120-credit program combining coursework and applied learning experiences. You’ll build technical expertise while gaining hands-on experience. Required coursework includes:

• Biology courses like Organisms and Environments, Structure and Function Across the Tree of Life, Genetics, Molecular and Cellular Biology and Advanced Evolution
• General and organic chemistry
• General or engineering physics
• Calculus and statistical methods or probability  
• A written communication course like Technical Writing or Grant Proposal Writing
• Additional biology electives that allow you to customize the degree to your interests and career goals
• Seminars and opportunities for undergraduate research that help you apply what you learn in the classroom to real-world scenarios

Class format

Many biology courses are taught with accompanying labs. This means you’ll have several sessions a week learning scientific concepts in a traditional classroom setting plus a weekly lab section to conduct experiments related to that week’s content. Lab sections are smaller, so you get personalized support from your instructor to help you succeed.

Research opportunities

Over 75% of undergraduate students at U of I do undergraduate research, often for academic credit or as paid lab assistants. You will gain lab experience in your regular classes, but you can also work with individual faculty in their research labs or field sites. For undergraduates in biology, that includes projects like:

• Exploring how zebrafish retinal cells regenerate after injuries in hopes of development new treatments for blindness in humans
• Studying how species adapt to new or changing environments
• Exploring the role of “killer yeast” strains in preventing fungal growth, with applications in everything from the microbrewing industry to human health care

Students working in research labs use scientific equipment like quantitative PCR instruments, fluorescence and confocal microscopes, kinetic plate readers, flow cytometers, and microbe plating robots. This gives you hands-on experience that can set you apart when applying for jobs.
