What is Integrative Biology?

Integrative Biology (IB) is the study of living organisms through an integrative lens. It pulls concepts and skills from many disciplines to answer questions about how life works, from the level of the gene to the global ecosystem.

As an IB student, you’ll delve into the study of life and research the interactions of (and in) biological systems. This major emphasizes a strong foundation in experimental design, communication skills, and critical thinking. Your coursework will include a great deal of experiential training. Many classes have a lab component. You’ll study topics like genetics, anatomy, physiology, behavior, ecology, and evolution.

The IB curriculum provides the foundational knowledge and skills necessary for a wide variety of careers. This includes healthcare, research, conservation, and more. You can visit IB's "alumni mentoring program profiles" page to see what our graduates are doing with their degrees.

If you're interested in this major, apply to our Biology program. You may choose IB as your major before your sophomore year. There is also an option for an IB Honors concentration. IB offers a Secondary Education option for the teaching of Biology in high schools.

1 Post-graduate data was collected through the Illini Success initiative, which primarily relies on self-reported survey data sources. Statistics are aggregated from the past three years. Please note that total compensation may be greater than annual salary as other forms of compensation (e.g., signing bonus, commission, benefits) are not included. For more information on Illini Success data and methods, please visit the Illini Success website. For average wage or salary information five years after entry into an occupation, visit the Post-Secondary Employment Outcomes Explorer.

2 Graduation and retention data comes from several majors within a similar interest area. Data may not yet be available for newly created programs. Years-to-degree data is only available for programs from which you can earn a degree. Retention and graduation rates are only available for programs that you can apply directly into. Retention rates reflect retention to the university, not necessarily retention within the major.

3 "Expenses" are estimated and include books, supplies, housing, and other living expenses. The exact amount you’ll pay depends on where you decide to live, the meal plan you choose, and your overall lifestyle.
