Welcome to IPHY

When CU-Boulder established the integrative physiology major in 2003, it was the first in the U.S. to bear that name. But the field -- in which cellular and molecular observations are linked to the health and function of whole organisms -- is growing fast. In just ten years it has become the university's second-largest major, with over 2,000 undergraduates as well as burgeoning masters and doctoral programs. The closest thing to a medical curriculum at CU-Boulder, Integrative Physiology provides an outstanding foundation for future doctors and nurses, and a firm basis for varied health professions and pursuits. It also provides a strong foundation for careers in basic physiological science.

The program's breadth and flexibility makes it popular among students, who can adjust their plans midstream to pursue their passions and explore new developments in fast-changing health disciplines. So does its faculty, whose research has attracted grants from the American Heart Association, the National Institutes of Health, and the National Science Foundation. The department ranks 14th nationally in faculty research grants and fourth out of 63 doctoral physiology programs, primarily competing with medical school physiology departments.

With the health care industry expected to grow by double the rate of other industries through 2014, we need to educate new health professionals now. Integrative Physiology at CU-Boulder is helping to fill the gap.

The video at the top of this page provides an engaging introduction to the IPHY Department, its strengths, and its role in launching students on their career paths. A brief history page describes the Department's origins.
