Bardeen taught at Johns Hopkins University from 1897 to 1904. He then left Johns Hopkins and accepted the post of professor of anatomy at the University of Wisconsin–Madison. Bardeen came to Wisconsin at a time when the university was expanding under President Charles R. Van Hise. Van Hise and Bardeen shared the view that the one element the university was missing was a medical school. Bardeen was asked to create a two-year program fully integrated into the university. In 1907, he became the first dean of the University of WisconsinMedical School. Bardeen wanted the new medical school to evolve into a four-year program. However, he had to battle local physicians, who believed that such an institution would rob them of their livelihood. Later, the First World War and the 1918 influenza epidemic convinced them, and the public, that more physicians were needed in Wisconsin. Finally, in 1924, Wisconsin General Hospital opened its doors, and a year later the Medical School invited students to participate in a four-year curriculum. However, the medical school had difficulty meeting the clinical needs of the extended curriculum. Bardeen had a solution. He wanted a co-opting of state physicians into the medical school's educational activities. Beginning in 1926, fourth-year medical students would spend eight weeks working in one of the many private practices scattered across the state of Wisconsin. The preceptorship rapidly grew into one of the most popular aspects of medical education at the university. Later, the preceptor concept introduced by Bardeen became an important national innovation. Bardeen contributed articles on embryology, morphology, anatomy, and other subjects to scientific journals.

Bardeen died in Madison, Wisconsin in 1935, from pancreatic cancer. He was succeeded as Dean of the University of Wisconsin Medical School by Dr. William Shainline Middleton.
