Professional career
Burk joined the Department of Agriculture in 1929 working in the Fixed Nitrogen Research Laboratory. In 1939, he joined the Cancer Institute as a senior chemist. He was head of the cytochemistry laboratory when he retired in 1974. He also taught biochemistry at the Cornell University Medical School

He later became head of the National Cancer Institute's Cytochemistry Sector in 1938, although he is often mistaken as leading the entire facility.

Retirement
After retiring from the NCI in 1974, Dean Burk remained active. He devoted himself to his opposition to water fluoridation
The water fluoridation controversy arises from political, ethical, economic, and health considerations regarding the fluoridation of public water supplies.
For deprived groups in both maturing and matured countries, international and national ...
. He and a coauthor published an analysis of cancer mortality in 10 cities that fluoridated the drinking water supply and 10 that didn't. The paper was criticized for using overly broad grouping and making assumptions about variations in racial composition of cities. Epidemiologists
