He began performing experiments with bacteriophages with Italian-American Salvador Edward Luria and German Max Delbruck in 1940, and observed that when two different strains of bacteriophage have infected the same bacteria, the two viruses may exchange genetic information.

He moved to Cold Spring Harbor, New York in 1950 to join the Carnegie Institution of Washington's Department of Genetics, where he performed the famous blender experiment with Martha Chase in 1952. This experiment provided more evidence that DNA, not protein, was the genetic material.
